4. BRINJAL
• Common Name: Brinjal, Eggplant
Aubergine.
• Botanical Name: - Solanum melongena L.
• Family:- Solanaceae
• Chromosome no. :- 2n = 24
• Mode of pollination:- Self-pollinated
• Out-crossing % :- < 5%

5. • Brinjal is one of the most common principle
vegetable in most parts of the world.
• In it’s natural habit, it is a perennial plant but
cultivated as annual.
• An erect bushy plant with compact and well
branched stem and deep root system.
• The brinjal is of much importance in the warm
areas of For East, being grown extensively in
India, Bangladesh, Pakistan, China and the
Philippines.
• It is also popular in Egypt, France, Italy and
United States.

6. Origin:
• Brinjal is native of India. According to A.
Decandolle.
• According to N.I. Vavilov, the eggplant
originated in the Indo-Burma region.
• More than 16 species of brinjal are found to
grow wild in various parts of the country.

7. Distribution:
• Brinjal is cultivated in most parts of the world.
• Leading countries are USA, China, India,
France, Bangladesh and Philippines.

8. TAXONOMY

10. Floral Biology
• INFLORESCENCE
• Inflorescence is
solitary or cluster of 2-
5 flowers.

11. Flower
• Flowers are
actinomorphic,
Hypogynous,
Hermaphrodite with
pistil sorrounded by the
stamens.
• White or pinkish in
colour, depending on
the cultivars.

12. • There are four types of flowers depending on
the length of the style and size of the ovary
viz:-
1.Long styled with big sized ovary.
2.Medium styled with medium sized ovary.
3.Pseudo styled with rudimentary ovary.
4.True short styled with very rudimentary ovary.

14. CALYX
• 5 gamosepalous,
Light green in colour

colour.
• Lobes are short.

15. ANDROECIUM

found either above or
on the same level or
below the stamens.

18. Anthesis and Pollination
• Flower generally emerge 40-45 days after transplanting.
• Anthesis occurs at about 6-8 am in august-September.
• Peak flower opening at 08:30 am to 10:30 am.
• Essentially a Self-Pollinated crop as stamens
surrounding the pistil &stamens dehisce at the same the
stigma is receptive.
• Self pollination varies between 80-92 %.
• Pollen viabiity is retained for 8-10 days at 20-30 degree
Celsius and R.H. of 50-55%.

19. Selfing techniques
• Bagging of young bud.
• Manual transfer of freshly collected pollen on
stigma of flowers of the same plant.

20. Crossing techniques
• Crossing techniques includes:
• Hand emasculation,
• Pollen collection,
• Artificial pollination or Pollen dusting.
• For emasculation, a healthy long or medium styled,
well developed bud from the central portion of the
plant is selected.
• The bud is opened gently with the help of fine pointed
forceps one or two days before the opening of the bud
and all the five anthers are carefully removed.

21. • For pollination,
freshly dehiscing
anthers are picked
up and are silt
vertically with fine
needle to get
sufficient pollen
flower bud.
• It is labeled and
covered with small
pollination bag.

22. Genetics of important qualitative
and quantitative characters
In India, the National Bureau of Plant Genetic
Research is the nodal institute for management
of germplasm resources of crop plants and
holds more than 2500 accessions of brinjal in its
gene bank.
The wide regional variations for plant, flower
and fruit descriptions revealed enough scope
for improvement of yield characters by selection.

23. Breeding objectives
The main objectives are to evolve hybrids that have
following traits.
High yield.
Earliness.
Fruit shape, size and colour as per the consumers
preference.
Low proportion of seed and more pulp.
Soft flesh.
Low olanine content.
Upright sturdy plant free from lodging.

24.  Give flowering and fruiting at very and high
Temperatures.
 Having straight growth habit
 Good attractive colour
 Less fruit thickness
 Resistance to:
1. Bacterial wilt (Pseudomonas solanacearum)
2. Phomopsis blight (Phomopsis vexans)
3. Little leaf (Mycoplasma like bodies)
4. Root knot nematodes
5. Shoot and fruit borer
6. To frost.

25. Breeding methods
• Pure Line Selection
• Pedigree Method
• Bulk Method
• Back Crossing Method
• Heterosis Breeding
• Mutation Breeding
• Resistant Breeding

26. Pure line selection
• Pureline is the progeny of a single self fertilized
homozygous individual.
• Pure line improvement is adopted to improve
heterogeneous foundation stocks and as a result, varietal
improvement is possible.
• Pusa Purple Long : -
• Selection from the Batia cultivar in Punjab.
• Long fruit, shine skin, early maturity.
• C.O.1:-
• Duration 160 days, fruits are oblong and medium sized
with pale green shade.

27. • Pant Samrat : -
• From GBPUAT, Pantnagar.
• Selection in local germplasm.
• Resistance to bacterial wilt.
• Tolerant to fruit and shoot borer.
• Pusa Purple Cluster : -
• IARI, Selection from local material.
• Medium early, erect, tall sturdy plant, fruit in
clusters of 4-9, 10-12 cm long, deep purple.
• Resistance to bacterial wilt.

28. Pedigree Method
• This method was adopted to develop material as
well a variety for high yield, earliness, quality and
resistance to pests, diseases and stress conditions.
• In this method, single plant selection is followed
up to F5 or F6generations and in advance.
generations, families are selected on the basis of
their phenotypic performance.
• Pusa Kranti : - PPL × Hyderpur × Wynad giant
• Plant medium tall, upright erect, less seeded.

29. Bulk method
• This method consists of growing large populations in
each generation and harvesting the seeds in bulk and
planting a sample of seeds in the following years.
• No selection is made in F2 and bulk populations
grown up to F5 or F6.
• No selection is made in F2 and bulk populations
grown up to F5 or F6.
• At the end of the bulking period, individual plants are
selected and evaluated in a similar manner as in the
pedigree method of breeding.

30. Back Crossing Method
• In the back cross method, the hybrid and the
progenies in the subsequent generations are
repeatedly back crossed to one of the parents.
• This method involves the selection of two parents
where one is the recurrent (agronomic) and the other
is the non-recurrent (donor) parent.
• The F1 population is grown in rows and tested for
resistance.
• This method is best executed in self-fertilized crops
than in cross fertilized crops and is usually applied to
transfer-resistance characteristics controlled by major
genes in cultivars.

31. Heterosis Breeding
• It is the superiority of F1 hybrid over both the parents in terms
of an increased vigour, size,growth rate, yield and a number of
other characteristics.
• Emasculation is done on buds, which are about to open on the
next day morning. Normally, single, long styled flowers are
selected for crossing.
• After emasculation, the flowers are covered with butter paper
cover and pollination is done on the next day morning.

32. • Arka Navneet : -
• Developed from IIHR, Bengaluru.
• Cross between IIHR 22-1 × Supreme.
• Fruit oval and free from bitterness, skin attractive,
deep purple, flesh soft, white with few seeds,
yield 650-700 q/ha (highest yielding variety in
India).
• COBHI : -
• It is a cross between EP45 x CO2.
• The fruits are medium sized, oblong and purple
deep in colour.
• Yield potential is 55-60 tones per hectare.

33. Mutation Breeding
• PKM-1 : -
• Developed at TNAU, Periakulam.
• It is an induced 1 mutant (gamma rays) of a local
type called Puzhuthi Kathiri.
• It is a drought tolerant and can with stand long
transportation.
• Yielding on an average 34.75 tones per hectare in
a duration of 150-155 days.
• The fruit weighs 45-to 65 g.

34. Resistance Breeding
• Brinjal like any other vegetable crop is susceptible to
number of diseases, pests and root knot nematode.
• Chakraborty and Choudhury (1975) –
reported selection of three brinjal lines viz. Sel.212-1,
Sel. 252-1 and Sel.252-1-2 as free from little leaf
disease out of 164 germplasms tested.
• According to Swaminathan and Srinivasan, 1971)
S.melongena var. insanum carries a single dominant
gene for resistance wilt and cultivar Black Beauty and
Vijaya are tolerant to root-knot nematodes (M. ncognito)
as reported by Yadav et al. (1975).
