6. INTRODUCTION
Chillie is both a vegetable crop & a spice crop.
It is rich source ofVitamin 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.

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.
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.

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.
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 1000-
2000 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
