• Important vegetable cum spice crop grown through out the world.

• Cultivated for green or dry fruit.

• ‘Capsicum’ = Greek word ‘kapto’, meaning "to bite" or "to swallow."

• Common names : hot pepper, sweet pepper, bell pepper, shimlamirch, paprika.

• Almost 400 types of chillis are grown through out the world.

• It comprises numerous chemicals including steam volatile oils, fattyoils, capsaicinoids, carotenoids, vitamins, proteins, fibres and mineralelements (Bosland and Votava, 2000).

• An important part of daily diet.

• Key Element in many regional cuisines, pickles, soups, sauce,Salads, curries etc. due to its unique flavor, aroma and colour.

• Increase the taste and palatability.

• Fresh green capsicum contain more vitamin C than citrus fruitsand fresh red chilli has more vitamin A than carrot. (Than et al.2008).

• Chillies are low in sodium and cholesterol free.

• Many other medicinal Properties are found…

• stimulate blood circulation

• improves the digestion process

• speed up the metabolic rate

• rich source of antioxidants

• boosts to the immune system

• blood thinning properties

• source of natural bactericidal agents

• Apart from medicinal uses chilli also used incosmetic , liquor industries and as a weaponfor self defense (chilli spray).

Scientific Classification

Page 11: Genetic improvement in chilli

Botany

• Herbaceous or semi-woody, annualsor perennials.

• Straight, woody stems and the leavesare ovate, tapering to a sharppoint, measuring up to 15 cm, darkgreen on the upper surface and palegreen on the lower surface.

• Flowers : small, star-shaped, whiteand borne singly or in clusters of 2 or3 in the axils of the leaves.

• The flowers are followed by juicelessberries which are green at first andchange to red, yellow or purple.

11

Page 12: Genetic improvement in chilli

• Fruits vary in shape, size, colour and degree of pungency as per the cultivar.• Fruit contain numerous flat, kidney-shaped, white seeds, which have very

pungent taste.• Pungency of Capsicum is due to an alkaloid “Capsaicin”• Red colour of fruit is due to the pigment “Capsanthin”• Domesticated species : larger but fewer fruits

wild species : more but smaller fruits but seed per plant is about the same.

12

Pedicel

Page 13: Genetic improvement in chilli

Flower: actinomorphic, bisexual, pedicellate, hypogynous Gynoecium: Bicarpellary, syncarpous, bilocular or tetralocular

due to pseudoseptum. Many ovules on axile placentation, ovarysuperior.

Androecium: Stamens 5, epipetalous Self pollinated crop. Flowers open at 5 a.m. Receptivity of stigma : from a day earlier to anthesis and up to 2

days after anthesis. Fertility of pollen : a day before anthesis with maximum fertility

on the day of anthesis. Emasculation and Pollination on the same day. Percent fruit set : 20% of the flowers produced. Isolation distance : 500 m. Hand emasculation and pollination is most common method

used for hybrid seed production in chilli.

Floral morphology

13

Page 14: Genetic improvement in chilli

Crossing technique

14

A bud one day prior to anthesis should be selected for emasculation

Emasculation should be carried out without damaging female reproductive parts and bagged it

At a same time pollen should be collected from the fully opened male flower

Gently transfer the pollen to the stigma , bagging and tagging should be done simultaneously

Page 15: Genetic improvement in chilli

• Capsicum genus includes 30 species, mostly classified aswild and semi-domesticated.

• Out of that five species are domesticated and cultivatedworld wide.

• C. annuum L. var annuum (bell pepper, chilli)

• C. frutescens L. (tabasco)

• C. chinense L. Jacq. (habanero)

• C. baccatum L.

• C. pubescens L.

• Three spices viz., C. annum, C. frutescens, and C. chinenseevolved from a common ancestor in a North Amazon basin

• Most of the chillies grown in India belong to C. annuum andC. frutescens species.

1. More number of fruits per plant

2. Higher fruit weight and larger size

3. Uniform fruit shape, size and color in sweet pepper

4. Earliness

5. Wider adaptability

6. Improved nutritional quality

7. Longer shelf life

Breeding objectives in Capsicum spp.

1. Higher yield

2. More pungency (capsaicin) and oleoresin in hot chilli

3. Zero pungency (capsaicin) and more antioxidant in sweet pepper

4. Resistance to anthracnose, virus complex, fruit rot and bacterial

wilt etc.

5. More dry powder from green fruit

Fully expanded lesions are sunken and range incolor from dark red to black in concentric rings

Causal Organism : Tobacco Mosaic Virus Transmitted by : whitefly Mosaic patterns consisting of bands of light

green or yellow alternating with dark green. Sometimes the leaves are crinkled or distortion. Plant growth is stunted.

High variability present in nature for quality and yieldcontributing characters.

Characters like fruits per plant, pricarp thickness, fruit size, fruitweight and oleoresin content can be used for selection.

Heterosis can be manifested using diverse germplasm. Easy and more hybrid seed production can be possible through

proper exploitation of male sterility system.Mutation can be employed to create new useful mutant for

crop improvement. In vitro cloning is more successful when cotyledon leaf was

used as an explants. Abiotic stress tolerant germplasm present in nature. Disease resistant cultivar can be developed through crossing

and backcrossing with resistance germplasm.68

Page 69: Genetic improvement in chilli

Development of varieties with inbuilt resistance against CMV andanthracnose.

Genesis of varieties with less pungency and consumer preference. Exploitation of male sterility and chemical hybridizing agents in

developing new hybrids. Introduction of heat and drought tolerance germplasm as a strategy for

climate change. Development of location specific varieties. Development of varieties with high dry matter (chilli powder) output. To develop a varieties which can maintain as such capsaicin content

even after a longer storage period. Developments of varieties with higher antioxident and oleoresin

content. Use of wild relatives in breeding programme based on embryo rescue

and somatic hybridization techniques. Breeding for ornamental plant type.

Future thrust
