This document presents information on a presentation about chilli breeding. It discusses the classification of chillies, introducing four main species - Capsicum annum, C. baccatum, C. frutescens, and C. chinense. It then covers the introduction, climate needs, soil requirements, irrigation practices, and self-pollination of chillies. Common and rare breeding methods for self-pollinating crops are also summarized, including plant introduction, mass selection, pure-line selection, hybridization techniques like pedigree, bulk, and single seed descent breeding.

6. INTRODUCTION
 Chillie is both a vegetable crop & a spice crop.
 It is rich source of Vitamin A & C.
 There are more than 400 varieties of chillies found all
over the world.
 It is also called as hot pepper, sweet pepper, bell
pepper etc.
 Its fruit is called as peprika.
 Both Chillie & Capsicum belong to the same
genus,i.e; Capsicum.
 Pungency in chillies is due to alkaloid capsaicin.
 Red color of chillies is due to the pigment capsanthin.
 Capsicum/Shimla mirch/bell pepper, is less pungent.

 C. frutescence known as
hot pepper.
 Perennial in nature.
 White colored flower.
 C. annum known as sweet

 Frits born in clusters and
thin peel.

 More pungent.
 Vit. - c content high.
 Self pollinated.
 Used as spices.
or bell pepper.
Annual in nature.
White, purple & radish
colored flower.
Fruits born singly and
thick peel.
Growth indeterminate.
Less pungent.
Vit.- c content low.
Cross pollinated.
Used as vegetable.

8. HISTORY
 Its species are native to
America ,where they
have been cultivated for
thousands of years.
 The three species C.
annuum, C. frutescens
and C. chinense evolved
from a common ancestor
located in the North of
the Amazon basin.

9. CLIMATE
 Growing chillies require warm growin




environment.
It is raised from sea level to 2000 meter
above sea level.
Optimum temperature for fruit set is 24 C.
Night temperature below 10 C fruit set
restricted.
Fruit weight, length, girth and pericarp
thickness were high at 25 C day and 18 C
night temperature.

10. SOIL & FIELD PREPARATION
 Chilli can be grown all
types of soils from light
sandy to heavy clay.
 Optimum soil pH for
chilli is 5.8 to 6.5.
 Very sensitive to water
logging.
 Thoroughly plough the
land 3-4 times followed
by planking to level the
field

11. IRRIGATION
 Chilli plant cannot withstand water
stagnation & excess moisture.
 Hence light irrigation &proper drainage is
recommended.
 Generally crop is irrigated at an interval of
5-6days in summer and 9-10 days in winter.
 Sandy soil require frequent irrigation than
clay soil.

12. 
INTRUSTING
BHUT JOLOKIA IS
THE WORLDS
HOTTEST
PEPPER.

14.  Chilli is self-pollinating crop.
 In which pollen grains transfer to stigma of
same flower or different flower in same plant.
 Such crops are highly homozygous.

15. Breeding methods for self
pollinating crops;
COMMONLY USED
METHODS/ GENERAL
BREEDING METHODS
RARELY USED
METHODS
Plant introduction
Mutation breeding
Selection(pureline, mass
selection, )
polyploidy
Hybridization(pedigree,
bulk, single seed descent,
backcross)
Transgenic breeding

16. PLANT INTRODUCTION: It is introducing a plant into new regions
from its growing locality.
 Proper management is very important.
 Material which is to be introduced should
not carry any pest and disease.

17. MASS SELECTION: It is oldest method.
 M.S refers to the selection of superior plants
on the basis of phenotype from a mixed
population. Their seeds are bulked &used to
raise the next generation.
 MERIT: Good for improvement of old cultivars&
landraces.
 For purification of improved cultivars.
 Mass selected varieties provide good
protection against diseases.

18.  Mass selected varieties are more stable in
performance than pure line varieties.
 DEMERITS: Progeny test is not carried out.
 The product is less uniform than pure line.


20. PURE-LINE
SELECTION:
 Merits:-
Isolate best
genotypes.
 Demerits: Do not
develop new
genotype.
 Have poor
adaptability
due to narrow
genetic base.

21. HYBRIDIZATION: Crossing of two dissimilar plants is known as
Hybridization.
 A cross is made b/w male parent of one
genotype & female parent of other genotype.
 We get F1 hybrid.
 BULK METHOD: F2 &subsequent generations are harvested in
bulk, &at the end individual plant selection
&evaluation is made in F8.
 Superior progenies are released as new
cultivar.

24. SINGLE SEED DESCENT METHOD: A breeding procedure used with segreggating
populations of self pollinated species in which
plants are advanced by single seed from one
generation to the next is referred to as SSD
method.
 In this method, a single seed from each of 10002000 plants are bulked to raise nnext generation.
 In F3 & subsequent generations one random
seed is selected from every plant in population &
harvested in bulk to raise the next generation
