4. FLORAL BIOLOGY
1. Inflorescence of wheat is called Ear or Head. In botanical it is
called as spike.
2. The unit is called spikelet. The sessile spikelets are arranged
acropetally in zig-zag manner on mother axis i.e. rachis.
3. Each spikelet consists of pair of outer glumes which encloses 3
to 5 florets. Central one or two are sterile and remaining florets
are fertile.
4. Each floret consists of outer glumes represented as scales,
awned lemma (flowering glume) and a palea.
5. The lemma and palea enclose three stamens (having thread like
filaments and versatile anthers),single carpel (with bifid stigma)
and two lodicules. The lodicules help for opening of flowers.
6.After fertilization, ovary develops into caryopsis, which is a
single seeded fruit with pericarp.
7. Flowers are bisexual and zygomorphic.
8. Wheat stamens are small and produce about 1000-4000 pollen
grains per anther.
Dr. V. Y. Pawar, A.C., Dhule
6. Flowering: Wheat is self-pollinated crop due to
chasmogamous or cleistogamous nature of
flower. Cross pollination may take place up to 1-
2%. Blooming starts after emergence of spike
from flag leaf. It starts in the main stem (mother
tiller) followed by the other tiller in the order of
development. Flowering in a spike begins in the
upper part of the spike and proceeds in both
directions. Blooming is continued throughout the
day and 3-5 days are required to complete it in a
spike. Immature green coloured anthers turn
yellow when matured. The stigmatic lobes are
closed together in young bud but separate out at
maturity. The lodicules absorb moisture and
swells due to which glumes are separated apart
in 20 minutes. The filaments elongate and
anthers dehisce within 2-3 minutes and at same
time stigma becomes receptive. The glumes are
again closed at the end of 15-20 min. Pollens
are viable for only 15 to 30 minutes and stigmas
remain receptive for 4 to 5 days and may
prolong to 13 days depending upon the
environment.
Dr. V. Y. Pawar, A.C., Dhule
7. Anthesis
• Blooming starts several days after the wheat spike emerges.The flowers on
the main stem (culm) bloom first and those on the tillers later, in order of the
tiller formation.
• Flower maturity starts from the middle part of the spike and proceeds in both
directions.
• Flowering continues throughout the day and takes 2-3 days for a spike to
finish blooming
• The glumes normally open during the flowering process. The anthers protrude
(emerge) from the glumes and part of the pollens shed outside the flowers.
• If the conditions are unfavourable for the opening of the glumes the anthers
may shed their pollen without being extruded (emerged).
Stigmas are receptive for 4 to 5 days under different condition but pollen is
viable for 15 to 30 min.
• Pollen remains viable for a very short period, usually not more than 15-30
minutes. Therefore, fresh pollen is essential for obtaining good seed set when
making crosses.
Dr. V. Y. Pawar, A.C., Dhule
8. Selfing technique:
•The spike is to be covered with butter paper bag prior to flowering to avoid the
crossing and then labelled it.
•Emasculation technique:
•Select spike in which anthesis will occur one or two days later.
•Remove awns with the help of scissors in such a way that small portion of glume,
lemma and palea is also cut. This will ease the removal of anthers.
•One fourth (1/4) lower and upper florets are removed. Keep 16-20 spikelets only with
the help of fine forceps, remove all three anthers in the evening or early morning.
•Take care that stigma should not be injured.
Crossing technique:
•Check the emasculated spike with a magnifying lance to ensure no anther left in the
floret.
•Bagging and labelling is done.
•Pollination is done on the next morning or on the 2nd day depending upon the
weather condition and stigma receptivity.
•Select the spike for pollination from pollen parent and remove it from plant. Keep the
spike in the sunlight for 10-15 minutes. Anthers will burst and pollen grains will be
released.
•The pollen grains are dusted on all the sides of emasculated spike.
•Bag the pollinated spike and label it properly.

9. Breeding objectives:
i) High grain yield potential with wider adaptability.
ii) Early maturity with short duration.
iii) Photo and thermo-insensitive varieties.
iv) Resistant to diseases like rust, loose smut, leaf blight etc.
and pests like aphids, armyworms and gujia weevil etc.
v) Responsive to high doses of fertilizers.
vi) Semi-dwarf varieties having synchronies productive
tillers.
vii) Resistant to water logging and shattering.
viii) Good milling and baking quality i.e. suitable for
chapatti and bread making.
ix) Amber grain colour and grain with high protein and
lysine content.
x) Heat, Salt and drought tolerant varieties.
Dr. V. Y. Pawar, A.C., Dhule
10. Breeding objectives: (In detail)
(1) Higher yield: High yield depends on
a) The number of heads / unit area
b) The number of grains / head.
c) The average weight of grain
While breeding for high yielding varieties all the above three
components must be
looked into. Omitting any one of them may not yield results.
(2) Lodging Resistance
This is achieved after the identification of dwarfing gene in
Japanese variety Norin10. Most of our dwarf wheats are two gene
dwarfs. E.g. Sonara 63, sonara 64, kalyan sona. Emphasis is now
on triple gene dwarfs.
Dr. V. Y. Pawar, A.C., Dhule
11. (3) Breeding for Quality:
a) Breeding for physical quality: The objective is to develop a variety
with well accepted physical characteristics like colour vitreousness,
texture/hardness, appearance, grain weight, test weight etc.
b) Breeding for chemical composition:
i. Starch composition: Modification of functionality of starch and
amylase and amylopectin content as per desirable end product such as
noodles, pasta, thickness, binding agents, bread etc. If the objective is to
produce starch with no amylase, then breeding for waxy type wheat would be
necessary
ii. Protein content: Wheat grain has a special significance of breeding
for high protein and low protein for bread and biscuit purposes respectively
and also for different end products.
iii. Nutritional quality: Wheat grains are deficient in lysine content.
Efforts are needed to improve lysine as well as high protein content to
improve nutritional quality of wheat.
iv. Breeding for market quality market quality: Includesphysical
characteristics, flour recovery milling quality, dough quality as well as gluten
content useful for specific product.
Dr. V. Y. Pawar, A.C., Dhule
12. (4) Disease resistance: Rust is the major disease.
The black or stem rust, brown leaf rust and yellow
or stripe rust are important ones. There are different
races of rust. So while breeding for rust resistance
horizontal resistance is to be looked into. Back cross
method of breeding and development of multi lines
are the methods.
(5) Insect resistant: The termites, aphids,
armyworm, American pod borer and brown mite
are the major pest of wheat which are mostly
controlled by chemically.
(6) Early maturity
(7) Drought resistance
(8) Winter hardiness

1. Introduction :
Semi dwarf wheat from Mexico,Sonara63, Sonara 64, Mayo 64,Lerma Roja 64
2. Pure line selection:
Earlier varieties like P4, P6, P12 evolvedat Pusa institute are resultof pure line
selectionfrom local population.
3. Hybridizationand selection
a) Inter varietal:
A number of successful derivativeswere developedat IARI New Delhi and
Punjab. NP-809 - New pusa multiple cross derivative.
However all these varietieswere lodging and poor yielder when compared to
other countries.Hence the wheat hybridizationprogramme was changed .
b) Inter specificcrosses
To get Hessian fly resistance.So also for rust resistance.
c) Back cross method of breeding
Rust resistance in Chinese spring fromThatcher.
Dr. V. Y. Pawar, A.C., Dhule
14. BREEDING PROCEDURES:
4. Hybrid wheat :
At Kansas Agri. Expt. Station USA male sterile lines were identified by
crossing T. timophevi x T. aestivum .
Dr. M. S. Swaminathan did extensive work on this with gamma rays.
Sharbati Sonara with increased protein content was evolved.
6. Development of multilines
Borlaug developed multilines against rust. MLKS 15 was developed at
IARI.
Multiline is a mixture of pure lines which are phenotypically similar
but genotypically dissimilar.
Each line is produced by separate back cross method of breeding. Each
line having resistance against a particular race of a disease.
Dr. V. Y. Pawar, A.C., Dhule
15. BREEDING CENTERS:
- International Maize and Wheat improvement Centre (CIMMYT)
Mexico.
-ICAR- - Indian Institute of Wheat and Barley Research
(IIWBR), Karnal.
-All India Coordinated Wheat Improvement Project (AICWIP) – Karnal
(earlier New. Delhi)
-MPKV- Agricultural Research Station, Niphad.
PRACTICAL ACHIEVEMENT:
The semi dwarf varieties of wheat have been developed through the
use of Japanese line Norin 10 as a source of dwarfing gene Rht1 & Rht2
which led to “green revolution” in wheat production.
The productivity of Semi dwarf varieties is about two and half times
more than old tall growing varieties. More over these varieties are
highly resistant to lodging and are highly responsive to fertilizer doses.

resistanceand leaf rust resistance.
4. Avena sterilis Dr. V. Y. Pawar, A.C., Dhule
18. Floral biology: oat
Inflorescences:
•Inflorescences of the oat plant is a panicle
composed of a central loose, open rachis
with five to seven nodes, from which
branches arise bearing spikelets.
•Each lateral branch terminates in a single
apical spikelet. Other spikelets are born on
second or third order of branches.
•Each panicle may have 20 to 50 spikelets.
•Spikelets consist of 3 to 4 florets enclosed
in two empty glumes, with the tip of one
glumes extending slightly above the other.
Florets within each spikelet are arranged
alternatively upon a central axis (rachilla)
and usually the two basal florets are fertile
but the third or fourth floret is sterile.
Dr. V. Y. Pawar, A.C., Dhule
19. Florets:
•The florets are perfect zygomorphic, bracteate and
hypogynous.
•It consists of a lemma and a palea, two lodicules, three
stamensand one pistil.
•Glumes are the two outer bracts of the spikelet. They are
broadly lanceolate, pointed, boat shaped, usually glabrous
and arched. The glumes may be pale, yellow or red.
•Lemma is a rigid structure which encloses the rachilla at the
base of the flower. Its primary function is to protect the
caryopsis. Lemma varies in colour from white, yellow, grey or
red to black. It may be awned or awnless.
•One membranous palea is present opposite to lemma.
Primary function of palea is to protect the caryopsis.
•Two small, smooth, pointed and shinning lodicules are
present at the base inside the floret.
•Androecium consists of three stamens.
•Gynoecium consists of single carpel with small hairy ovary,
short style and bifid stigma.
•A single sessile ovule is located inside the ovary.
Anthesis: Self-pollination is the rule but cross-pollination may range from 0.5-1.0
per cent.
The stigma becomes receptive one day before anthesis and remains receptive for five
days. Anthers dehisce the pollens just before or during opening of the floret.

20. MAJOR BREEDING OBJECTIVES
1) Breeding for high yield.
2) Breeding for adaptability, salinity, water stress and temperature
3) Winter hardiness & forage production.
4)Good quality varieties with high protien content and large grain in order to meet to
needs for oat-flake processing.
5)Lodging and shattering resistance :
Oats must stand in the field until harvested, without loss either from lodging or
shattering, if high yields are to be obtained.
6.Breeding for disease resistance
- Rusts , Crown rust, Stem rust, Smuts, Powdery mildew
7. Improved value of the oats for human consumption.
8.Improved value of oats for ruminants:
9.Improvements in naked oats for non-ruminants and industrial fractionation
Dr. V. Y. Pawar, A.C., Dhule
21. 1. Greater economic competitiveness of oats: Obtained through breeding for higher yields
(components of higher yield are spikes per unit, kernels per spike, 1000-grain weights); stiff straw
(resistance to lodging); high resistance to diseases such as mildew, crown rust and oat mosaic
virus; growing in cool and high altitude mountain regions with a mixed system cropping and animal
husbandry, etc.
2. Improved value of the oats for human consumption: By selecting for important components
of milling quality such as high kernel content, hullability, low proportion of screenings and minimum
grain blackening and breakage. Increased beta glucan content is another desirable target which
contributes to the health claims attributed to oats.
3. Improved value of oats for ruminants: High metabolisable energy is targeted by breeding oats
with thinner husks or with lower lignin content, above average oil content and tall height (>120 cm).
4. Improvements in naked oats for non-ruminants and industrial fractionation: Targets are for
higher yield, oil and protein content (>17%). An additional target is lower trichome density to reduce
irritation at harvesting and subsequent grain handling.
5. Reduced environmental input: An understanding of nitrogen and water use by oats to enable
selection of and breeding for more efficient varieties which will contribute to sustainable agriculture.
Characteristics of oats for rain fed areas:
good tillering ability, both high grain and vegetative harvest indices, longer growing period, growing slowly at
the seedling stage, fast grain-filling rates, taller plant heights, large spikes, well-developed root systems.
Characteristics of oats for irrigated conditions:
Shorter growing times (90 days) and short statures (95-100 cm), lodging resistance, uniform tillering with
more florets and kernels, tolerance to high water and fertility conditions, a good combination of yield
components (4.8- 6.7 million spikes per hectare, 35-50 seeds per spike, and a 1000-grain weight of more
than 20 g), Resistance or tolerance to Smut, rust, and BYDV diseases and aphids.

Botanical name: Hordeum vulgare,
Chromosome Number: (2n=2x=14).
Family: Poaceae (Gramineae), Sub-family: Pooideae
Centres of origin: Near East or Middle East or Ethiopia.
Distribution of species: Barley is cultivated in Russia, France, Germany,
Ukraine, Canada, Spain, U.K, and Turkey. In India, major barley producing states
are Rajasthan, Uttar Pradesh, Haryana, Punjab and Madhya Pradesh.
Wild relatives: Hordeum spontaneum - contains genes for
drought tolerance.
Dr. V. Y. Pawar, A.C., Dhule
25. FLORAL BIOLOGY
1. Inflorescence of barley is called Ear or Head. In botanical it is
called as spike.
2. The unit is called spikelet.
3. Each floret consist of lemma, palea, androecium and gynoecium.
4. Flowers are bisexual and zygomorphic.
5. Each floret has three stamens with large anthers and a pistil
bearing bifid feathery stigma.
6. Barley stamens are small and produce about 1000-4000 pollen
grains per anther.
Dr. V. Y. Pawar, A.C., Dhule
26. •Each spikelet is single flowered and
consists of two glumes and a floret.
•In six-rowed barley, three spikelets are
attached at each node of the rachis, and
these triplets alternate from side to side of
the rachis.
•In two rowed barely, only the central
spikelet of a triplet is fertile.
•The flower is enclosed in lemma and
palea.
•The pistil has a two branched feathery
stigmas.
•Three anthers are attached to the long
slender filaments.
•The spike of barely besides being
characterized as six-row and two-row, is
also described as hooded vs. awned.
•The hood is a three-lobed appendage at
the tip of the lemma.
•The hood may be either slightly elevated
on a short awn segment or sessile.
Dr. V. Y. Pawar, A.C., Dhule
27. Fertility of the lateral spikelets forms the
basis of barley classification and the
cultivated barley may be classified into
three main groups viz.,
i) Six rowed barley (H. vulgare L. emend,
Lam) In six-row barley, all of the spikelets in
a triplet are fertile and able to develop
grains. The central seeds are round and flat
but lateral seeds are slightly asymmetric and
smaller. In two-row barley, only central
spikelet is both male and female fertile. Each
spike may carry 25-60 kernels in six-rowed
varieties or 15-30 kernels in two-rowed
varieties.
ii) Two rowed barley (H. distichum, L.
emend, Lam) The two lateral spikelets are
smaller and sterile as they have reduced
stamens and a rudimentary ovary and
stigma. Thus only a single flat seed is
produced at each node of the spike. . Each
spike may carry 15-30 kernels in two-rowed
varieties.
iii) Irregular barley (H. irregular, E. Aberg
and Wiebe) Dr. V. Y. Pawar, A.C., Dhule
28. Breeding Objectives :
i) Breeding for high yield
ii) Breeding for adaptability, salinity, water stress and
temperature.

CHICKPEA
NAME - Cicer arietnum,L.
FAMILY – Leguminoceae
CHROMOSOMENO. – 2n=16
ORIGIN -
The chickpea is most probably originatedin an area of present day south-
easternTurkey and adjoining Syria.
RELATED SPECIES - C. reticulatum,C. pinnatifidum,C. songaricum
Two main categoriesof Chickpea are recognizedwhich are distinguished mainly
by their seed characteristics.They are
1) Desi types, which are relativelysmaller,angular seeds with rough yellowto
brown colouredtestas.
2) Kabuli types, with large,more rounded and cream colouredseeds.
Dr. V. Y. Pawar, A.C., Dhule
33. There are two main kinds of chickpea.
I. Desi (microsperma): It has small, darker seeds and a rough coat, cultivated
mostly found in Mediterranean to central Asia. Desi types are generally
smaller in stature with small leaflets and pods and posses predominantly pink
colour flower.
II. Kabuli (macrosperma): It has cream or beige colored, larger seeds and a
smoother coat, mainly found in the western Mediterranean region. Kabuli type
are generally taller with has white flowers.
Dr. V. Y. Pawar, A.C., Dhule
34. WILD SPECIES
The wild species of Cicer (Proginator)closelyrelated to chickpea are :
i) C. bijugum
ii) C. echinospermum
iii) C. ecticulatum
FLORAL BIOLOGY
1. The flowers are papilionaceous.
2. They are solitary in axillary racemes.
3. Double flowers are rare,but are very much sought after by the breeders as
possible sources of yield increase.
4. The calyx has five deep lancelolate teeth. Peduncle and calyx are hairy.
5. Generally,corollais white.
6. The vexillum is obovate,8-11 mm long and 7-10 mm wide.(The posteror large
bilobed petal of the papilinaceous corollais called standard or vexillium)
7. Wings are obovate,8-9 mm long. The keel is 6-8 mm long.
8. Number of pods/plant is highly variable,generally between30 and 150
depending on the year, location,sowing time and other factors.
Dr. V. Y. Pawar, A.C., Dhule
37. Floral biology:
•The flower is typically papilionaceous, zygomorphic, solitary, axillary, polypetalous
and bisexual with vaxillary aestivation.
•However, cultivars with two or three flowers are known. The peduncle is short jointed
and arises from the leaf axils opposite to the leaf. Peduncle and calyx are hairy. The
flowers are small, white and violet.
•Each flower has 5 sepals, 5 petals, 10 stamens and the carpel with its style is born
laterally on the ovary.
•Calyx: The calyx (8 to 10 mm) is composed of five partly joined sepals which makes
it gamosepalous. The two sepals are large and three are small. The calyx tube is
oblique, lanceolate and densely covered with hairs.
•Corolla: The vexillum is obovate, 8-11 mm long and 7-10 mm wide. Wings are obovate,
8-9 mm long and keel is 6-8 mm long. The corolla may be greenish white, purplish pink,
red or blue in colour. The standard petal is broad and clawed, the wings are free and the
keel incurved. Thus corolla consists of 5 petals (2+2+1).
•Androecium: The androecium is composed of 10 stamens i.e. nine fused and one is
free (9+1, diadelphous condition). The length of stamens varies from 6 to 8 mm. The
anthers are bi-celled, orange and basifixed.
•Gynoecium: The gynoecium consists of a superior ovary with a terminal slightly curved
or upturned style and blunt knot-like stigma. The ovary is ovate, pubescent, 2-3 mm
long, 1-1.5 mm wide and has 1-3 ovules or rarely 4. Generally style is glabrous and 3-4
mm long. The stigma is globose type
Dr. V. Y. Pawar, A.C., Dhule
38. Selfing Technique: Covering the flowers with paper bag.
Emasculation:
Emasculation is generally performed in the afternoon. The flowers
in hooded bud stage are
selected for emasculation.
Crossing technique:
•Pollination is carried out next day morning. The white bud stage
is most suitable for crossing because at this stage, stigma is most
receptive and pollen viability is high.
•However, crossing attempts involving either emasculation or no
emasculation have given erratic results (23 to 98% hybrid seed)
and this compounded by the low rate of natural seed set (18 to
52%) due to flower drops.
Dr. V. Y. Pawar, A.C., Dhule

48. FLORAL BIOLOGY
•The inflorescence is a capitulum or head, characteristic of composite family.
•The number of flowers in oilseedcultivars may vary from700 to 3000.
•The flower of the outer whorl of the head are called as ray florets.
•They have five elongatedpetals which are united to form straplike
structures.
•They have vestigeal styles and stigmas and no anthers.
•The other flowers arrangedin concentric rings over the remainder of the
head are called as disc flowers.
•Five anthers are united to forma tube with separate filamentattached to
the base of the corollatube.
•Inside the anther tube, there is the style,terminating in a stigma which is
divided.
•The receptive surfaces of stigma remainin close contact in bud stage.
•The achene or the fruit of the sunflower consists of a seed oftencalled the
kernel.
•The adhering pericarp is usually called the hull.
•The seed consists of seed coat, endospermand embryo.
•Major part of embryo is in the formof cotyledons.
Dr. V. Y. Pawar, A.C., Dhule
49. Inflorescence: The inflorescence is heterogamous
capitulum or head The shape of head may be concave,
convex or flat attached to main stem at varying angles.
Head is surrounded by involucre of bracts (phyllaries)
which vary in size and shape. Sunflower head consists of
two types of flowers, viz., disc florets and ray florets
which are arranged in concentric circles on receptacle.
Ray florets: Present in peripheral region, braceate,
sessile,incomplete Zygomorphic, unisexual, unisexual,
pstillate, pentamorphous, epigynous,cyclic.
Calyx-sepals-2,reduced to papus
Corolla-petals-5,gamopetalous, valvate,ugulate
Androecium-absent
Gynoecium-Bicarpellary, syncarpous, ovary inferior,
basal placentation
Disc florets: Situated in the centre of inflorescence,
bracteate. Disc florate are sessile, tubular, bisexual,
actinomorphicepigynous,cyclic.
Calyx-Sepals-2,reducedto papus
Corolla-Petals-5,gamopetalous, tubular
Androecium: Stamens-5, syngenesious i.e. anthers fused
to form tube around the style, epipetalous basified,
introse.
Gyonoecium: Bicarpellary, syncarpous, ovary inferiorone
chambered, basalplacentaton, style short,stigma bified.
Fruit-Cypsela type
Dr. V. Y. Pawar, A.C., Dhule
50. Selfing technique:
Self pollination is achieved by placing a muslin cloth bag over the head before anthesis.
Seed set can be increased by rubbing pollen from the newly opened inner florets on the
stigma of outer florets with a cotton pad or with a soft brush. Seed setting under bags
without rubbing with brush indicates the extent of self fertility.
Crossing techniques:
•Sunflower is protoandrous, in which the androecium matures earlier than the
gynoecium. There is a time lag of 18-24 hours in the maturity of male and female parts.
Because of this, cross-pollination is favoured by insects, particularly bees which play an
important role in pollination and fertilization.
• A single head produces 350 to 2000 seeds. The seed is called achene and consists of
outer pericarp, thin and papery inner seed coat and embryo.
• For attempting crossing in sunflower, the heads must be covered with bags prior to
flowing to prevent natural cross-pollination.
•For emasculation, the anthers of the disc florets of the female parent are removed with
the help of forceps early in the morning before they have dehisced and before the
stigmas have extended far enough into the anther tubes.
•Pollination is carried out the day after emasculation when the stigmatic lobes have
separated and the receptive surfaces are exposed. For this purpose, the pollen is
collected from the heads covered with bags before flowering and applied with a brush or
a piece of cotton to the female parent.

ix) Resistance to insect pest: Head damaging pest, grasshopper, jassids, leaf eating
Dr. V. Y. Pawar, A.C., Dhule
52. Breeding objectives:
1. Higher yield: Higher diameter of capitulum, higher number
of disc floret and high test weight contribute towards higher
yield.
2. Early maturity: Suitable for dry land and in spring situation.
3. Lodging resistance and dwarf type
4. Breeding varieties with high oil content: Complex character
yield and oil content are negatively correlated, to increase oil
content the shell must be thin. Breeding for high oleic acid and
linoleic acid and low chlorogenic acid
5. Breeding for self fertile lines: Protoandry and self-
incompatability mechanism
operates in sunflower. Hence hand pollination is necessary. To
avoid this self fertile lines should be evolved.
6. Resistance to biotic and abiotic stress:
• Disease: Alterneria blight, rust and downy mildew.
• Abiotic stress: Drought and salinity tolerance.
7. Resistance to bird damage

Dr. V. Y. Pawar, A.C., Dhule
54. 5. Head to row and remnant seed method
Developed by Pustovoit in Russia. By this method oil content is
increased. In this method the following are the steps:
a) From open pollinated type a large no (10,000 to 12,000) plants
are selected based on Head size.
b) The selected lines are analysed for oil content and high oil
content lines are isolated (1000 plants).
c) Part of the seed reserved and the part is sown in progeny rows
along with check to estimate yield.
d) Second season testing is also done. The best lines are
identified.
a. The remnant seed of elite plants which give high yield were
raised in isolation and multiplied for crossing interse next season.
b. The multiplied lines also tested for oil content and high yielding
high oil content lines were raised in isolation and crossed interse.

selection method also popularly known as varietal renovation method. This
method has been successfully used for developing open-pollinated varieties.
4. Development of synthetic and composite varieties
5. Backcross method
6. Mutation Breeding:A wide range of variability for oil content, fatty acid
composition, morphological characteristics, test weight, hull content and
flowering has been reported in mutants.
7. Molecular breeding: this includes:
• Genetic transformation of disease resistance
• Gene tagging for high oleic production
• Molecular characterization of sunflower species and domestic cultivars
HeterosisBreeding:
• Hybrid cultivars have distinct advantages over open pollinated varieties in
form of production stability, response to high-input, high self fertility, uniformity
in growth and maturity.
• CGMS system is used for commercial hybrid seed production in sunflower.

5. The inflorescence is racemose and flowering is indeterminate beginning at
the lowestbud on the main raceme.
6. The syncarpous ovary develops into a pod (silique) with two carpels
separated by a false septum.
Dr. V. Y. Pawar, A.C., Dhule
85. Anthesis:
•The flowers begin to open from 8.00 a.m. to 12.00 noon.
•The flowers continue to open till 3-4 days and on the 4th to 5th
day, the petals and sepals are shed.
•As the flowers open, the anthers begin to dehisce from the
apex downwards.
•At the time of dehiscence, the pollen liberating sides of the
anthers, remain towards the stigma and slightly shaking of the
flowers by wind etc. is sufficient to accomplish the transfer of
pollen.
•Large numbers of bees visit the flowers soon after they open
and certain amount of cross-pollination takes place.
Selfing technique: Selfing is carried out using muslin cloth
bags effectively. Either the whole plant or a branch is bagged
to ensure self pollination.
Dr. V. Y. Pawar, A.C., Dhule
86. Emasculation:
•When the plant just commences its peak-bloom period, a lateral
shoot without any fruit of the first or second order is chosen.
•About six to eight buds, likely to open on the following day or a
after that, are left for emasculation and other are removed.
•The stamens are removed with help of fine forceps or with a pair
of scissors.
•After removal of stamens, the opened buds are closed gently by
rubbing the forceps along the sepals in an upward direction and
cover the emasculated bud by muslin cloth or paper bag.
Crossing technique:
•Ripen anthers from fresh flower are collected in the morning
(around 7 am) of the next day and placed under sun rays for
dehiscence.
•Pollination is made by dusting pollens to stigma.
•After pollination the flowers are again bagged.

87. Breeding objectives
1. High yield
2. Early maturity
3. High oil
4. Low erucic acid and glucosinolates
5. Resistance to diseases
6. Resistance to insects pest
Dr. V. Y. Pawar, A.C., Dhule
88. Breeding objectives:
1. Higher seed yield per unit area: By increased number of
branch, pods per plant, seeds per pod and seed size. Further
yield can be increased by increase in biomass, harvest index and
maximum light penetration of crop canopy
2. Early maturity: Need to develop early maturing varieties for
multiple cropping sequence with higher per day productivity.
3. Resistance to biotic and abiotic stress:
• Important Diseases: Alternaria blight, white rust, powdery
mildew, downy mildew collar Rot, white stem rot and wilt.
• Important Pest: Aphids, saw fly, painted bug, leaf miner and
Bihar hairy caterpiller- so far no resistance source identified.
• Abiotic stress: Drought, salinity and frost resistance is needed
to prevent yield losses. Winter hardiness is very important.
4. Shattering resistance: It is necessary to breed the varieties
in which siliquae hold the seed for sufficient time after maturity.
Dr. V. Y. Pawar, A.C., Dhule
89. 5. Higher oil content (45 per cent) and oil quality:
•Erucic acid and glucosinolate and fibre are the antinutritional factors in
seed oil and seed meal (deoiled cake), respectively.
•Glucosinolate is a group of compounds that give the characteristics flavor to
vegetable and condiment. In meal, it is relatively high, therefore, restricted to
use in cattle feed.
• Low Erucic acid (<2 %) in seed oil and low glucosinolate (<30 μ moles
glucosinolate/g) of deoiled cake and low fiber is designated as “Canola”
(commonly known as triple low ‘000”) are considered as ideal for consumption
as food and feed.
•It necessary to develop varieties are having high oil content, high protein with
higher quality,high crude fibre, low Erucic acid (<2 %) low glucosinolate (<10
μ moles glucosinolate/g) and low fiber.
•High content of long chain fatty acid, erucic acid up to 50 per cent is
desirable in oil, which is used as lubricant. But for the edible purpose it
should be low.
• Linolenic acid should be reduced (<3%) as it very unstable and is easily
oxidized to give unpleasant smelling substance in oil.

91. Breeding methods:
1. Hybridization: It is used to combine the desirable characteristics of two or more
genotypes through inter-varietal or inter-specific crosses.
2. Mass selection: Mass selection is used to increase the frequency of desirable
genotypes in population in both self-pollinated and cross-pollinated Brassicas, but
there is no recombination among selected genotypes in case of self-pollinated
Brassicas.
3. Pure line selection: Several successful varieties have been developed by using
pure line selection in land races of yellow sarson, Indian-mustard, karan, rai and gobhi
sarson.
4. Bulk method: This method can effectively use for improvement of those
characters whose expression is depend on occurrence of favourable environment such
as frost, drought, disease and pest.
5. Pedigree selection: It is the most commonly used selection method for cultivar
development in self-pollinated Brassicas.
6. Backcrossing: This method is used to transfer a range of traits, such as low
erucic acid, low glucosinolets, seed colour, disease resistance, male sterility and fertility
restorer genes.
7. Recurrent Selection: This method is used in cross-pollinated Brassicas such as
toria, brown sarson, black mustard and taramira for increasing seed yield and oil
content by increasing frequency of desirable alleles through selection of superior
recombinants.
Dr. V. Y. Pawar, A.C., Dhule
92. 8. Developmentof synthetic and Composite varieties: Synthetic and
composite varieties are developed in self-incompatible and cross-pollinated
Brassicas to exploit part of available heterosis.
9. Hybrid breeding: This method is used to exploithigh heterosis for seed
yield in hand bred F1 obtained by employing CGMS system.
10. Polyploidy breeding: This method can be used widen the genetic base
of digenomic species.
11. Mutation breeding: Thismethod is generally used for rectification of a
single deficiency or creation of a single desired characteristics in otherwise
agronomically superior variety. The traits such as yellow seededness coupled
with high oil content has been improved through induced mutation.
12. Anther and microspore culture techniques
13. Re-synthesis of amphidiploids: This technique could be used to widen
the genetic base of natural amphidiploids
14. Molecular breeding: This technique has following uses:
• Molecular markers can be used to identify somatic hybrids, cybrids,
somaclones and cytoplasmic lines in oilseed Brassicas.
• Identification of genes responsible for specific traits such as high erucic acid.
• Genetic modification through genetic engineering technique e.g.
Barnase-Barstar reproductive system which induced male sterility and
fertilityrestoration.

94. Genetically Modified (GM) Mustard hybrid in India:
•The Genetic Engineering Appraisal Committee (GEAC) of
Government of India has approved the environmental release of
Genetically Modified (GM) Mustard hybrid DMH-11 and its parental
lines on 18th October, 2022 for its seed production and testing as per
existing ICAR guidelines and conditions imposed by the GEAC.
•Dhara Mustard Hybrid-11, otherwise known as DMH-11, is
a genetically modified hybrid variety of the mustard species Brassica
juncea.
•It was developed by Professor Deepak Pental from the University of
Delhi, with the aim of reducing India's demand for edible oil imports.
•DMH-11 was created through transgenic technology, primarily
involving the Bar, Barnase and Barstar gene system. It is a genetically
modified variant of Herbicide Tolerant (HT) mustard.
•DMH-11 is a result of a cross between Indian mustard variety
‘Varuna’ and East European ‘Early Heera-2’ mustard.
Dr. V. Y. Pawar, A.C., Dhule
95. •It contains two alien genes (‘barnase’ and ‘barstar’) isolated
from a soil bacterium called Bacillus amyloliquefaciens that
enable breeding of high-yielding commercial mustard hybrids.
•Barnase in Varuna induces a temporary sterility because of
which it can’t naturally self-pollinate. Barstar in
Heera blocks the effect of barnase allowing seeds to be
produced.
•DMH-11 has shown approximately 28% more yield than
the national check and 37 % more than the zonal checks and
its use has been claimed and approved by the GEAC.
•“Bar gene” maintains the genetic purity of hybrid seed. The
insertion of the third gene Bar, enables DMH - 11 to
produce phosphinothricin-N- acetyl-transferase, the enzyme
responsible for glyphosate resistance.

P. Benthamii
DISTRIBUSTION :- China,India,USA,Srilanka,Bangladesh
Dr. V. Y. Pawar, A.C., Dhule
101. FLOWER BIOLOGY
1. The inflorescence is a stiff terminal bristly spike, up to 15-20 cm
in length, yellow-brown to purplish in colour.
2. Spikelets are arranged around a hairy axis, and fall at maturity.
3. Spikelets are 4-6 mm long and surrounded by 2 cm long plumose
bristles.
4. There is little or no seed formation.
5. When seeds are present they are very small (3 million seeds/kg)
P. purpureum relies on wind to achieve cross-pollination,
due to asynchrony of male and female flower parts.
6. However, this is also an apomictic species which can produce
seed by this asexual method of reproduction (Brown and
Emery, 1958; Stevens, 2012).
7. The species is an inconsistent seed producer and in some habitats
it rarely develops seeds, possibly due to low pollen viability
(Tropical Forages, 2013).
8. When seeds are produced they are dispersed by wind (Francis,
1992), but are often off.

103. CONVENTIONAL BREEDING
➢Napier grass is a cross-pollinating allotetraploid species with
a chromosome number of 2n = 4x = 28 (genome A’A’BB).
➢Although there is no clear information on the genetic origin
of allotetraploidy in Napier grass, the A’A’ genome has been
reported to be homologous to the AA genome of pearl millet
(Pennisetum glaucum (L.)) and the A’ chromosomes are larger
than the B chromosomes, which contribute genes controlling
the perennial growth habit .
➢To date, Napier grass ‘improvement’ has mainly been based
on the evaluation and selection of existing accessions for
traits of interest.
Dr. V. Y. Pawar, A.C., Dhule
104. ➢For example,accessions were screenedfor resistance to diseases,and
Napier grass head smut- and stunt-resistantlines were identifiedfromthe
existing collections.
➢Plant breeding and selectionin Napier grass has primarily been aimed at
improving differentagronomictraits such as disease resistance,yield,
nutritional quality, growthhabit (dwarfing), palatability and abiotic stress
tolerance.
➢ Napier grass is cross-compatiblewith the closely relatedspecies pearl
millet(Pennisetum glaucum) (2n = 2x = 14, genome AA) the resultant
hybrids are triploidand sterileand can only be propagated by vegetative
means which, although labour intensive,ensure a trueto- type variety.
➢A number of agronomically importanttraits, nutritional quality and
palatability for example,have been introgressedinto the genome of Napier
grass frompearl milletthrough conventional plant breeding and hybrids
have become a crucial part of the forage cropvalue chain in Africa, Asia and
South America.

122. BREEDING PROCEDURE
Sorghum is often cross pollinated crop. So to maintain varietal
purity isolation distance of 400 meters is necessary. Compared to
other often pollinated crop like red gram, maintenance of inbreds
is easy in sorghum. By putting brown paper and selfing the genetic
purity can be maintained.
1. Introduction : Varieties of milo and kafir sorghum introduced
from USA are used in conversion programme to convert the local
long duration photo sensitive varieties to short duration, non-
photo sensitive lines.
2. Selection : Old varieties like Co1, Co2, Co4 are all selection made
from local land races.

7. Population improvement:
With the use of cytoplasmic genetic male sterility as well as genic male sterility we
can go for population improvement.The local land races can be used as pollinators
and by half sib familyselection, we can isolate lines. We can follow recurrent
selection idea to develop superior inbreds.
8. Use of Apomictic lines :
Some apomictic lines have been identified which can be utilised in breeding
programme and by vegetative propagationwe can fix up heterosis.E.g. R473 from
Hydrabad.

Initially the varieties were all introduced one.
Sikkim primitive 1
Sikkim primitive 2.
Mexican line were first introduced during 16th century by
Portugeese
2. Mass Selection : Prior to 1945 mass selection was the only
method used for maize
improvement.
KT 1 - U. P.
RAS 1 - Rajasthan.
By adopting mass selection technique it is possible to get yield
increase by 19% per cycle.
Dr. V. Y. Pawar, A.C., Dhule
132. 3. Ear to Row Selection :
First proposed by Hopkins for improving oil and protein content
of maize.
This method involves selection of a number of phenotypically
desirable ears out of a population grown in
isolation. The selected cobs are harvested on single plant basis
and keeping part of the seeds and remaining sown in rows.
Based on the best performing rows during next season the
reserve seeds are sown.
This method is suitable for characters having high heritability
like oil content and protein content. But it was not helpful to get
increased yield.
Dr. V. Y. Pawar, A.C., Dhule
133. 4.Modified Ear to Row method :
Proposedby Lonnquist: Mostsuccessful method of progeny selection
I. The progeny test consist of a replicated yield trial in place of single
row so that environmental effects can be separated and the actual
value of each progeny can be more accurately estimated.
II. In this case progenies from the selected plants are planted in a
replicated yield trial as well as in crossing block (recombination or
seed production plot). The progenies in a crossing blocks are
detasseled, they are pollinated by pollen from the rows of a
random bulk from all the progenies of selected plants planted after
every 2-3 progeny rows. Superior progenies are selected and their
seeds are harvested separately. Progenies from the selected plants
are handled in the same way as outlined above.
In this Scheme:
1.The evaluationof progeniesis based on replicatedtrials
2.The source of pollenis controlled.
3.Each selectioncycle is completedin one year.
•Seeds of progeny test are obtained by mating the selected plants in
pairs so that the plants within a progeny are full-sibs i.e. have both the
parents in common.This is commonly known as full-sibfamily selection.
Dr. V. Y. Pawar, A.C., Dhule
134. 5. Hybridization and Selection
Not popular since isolationof superior recombinants was not made.
6. Heterosis breeding :
•Instead of using CGMS lines,detasseling the female inbredline is followedin India.
•Since use of CGMS line is costlier comparedto detasseling it is not followed.
•Crossing the inbreds of indigenous x exotic originresultedin release of best hybrids.
•Indian x Indian - 24 to 43% yieldincrease.
•Indian x U.S. dent – 58 % yield increase.
•Indian dent x Caribbean Flint – 47 to 54 % yieldincrease.
