Description The chilli (also chili orchile) is a member of the nightshade
fam ily, Solanaceae. It is an important spice, condiment,
vegetable crop, being cultivated since prehistoric times
in Peru and Mexico. The pungency of chilli is due to
capsaicin, which has medicinal value also. When chilli
is eaten it makes the brain to release endorphi ns, a
natural pain killer present in the body. The endorphin
lowers blood pressure and helps to fight against cancer.
Being an often cross-poll inated crop, it exhibits wide
variability for different quantitative and quali tative traits.
Thus, there is a wide scope of improvement through
heterosis breeding among genetically diverse genotypes.
Information on combining abi lity facil itates the choice of
suitable parents for hybridization programme to develop
promising F 1 hybrids. The di allele mating design helps in
determining both general and specific combining abil ity
of parents and hybrids combination, respectively. Fu1ther
it helps in formulating the suitable breeding strategy for
improvement. Therefore, the present study was undertaken
to identify suitable potential combination in order to have
superior F 1 hybrids.
Genetic analys is was carried out through diallele method for estimation of combining abi lity using nine parents. The analysis revealed that parents and crosses differed significantly for general and specific combining ability effects. The relative magnitude of gca variances was higher than the sea variance, indicates the role of additive component in the expression of all the traits except green fruit yield which was found to be under the control of non-additive gene action. The parents HC-7 for green fruit yield. fru it weight, fru it length, and earliness, HC-5 1 for green fruit yield, number of fruit per plant and earliness were found to be the best general combiner. The crosses HC-7 x HC- 51 , HC-8 x HC-37 and HC-5 1 x HC-34 were the best specific crosses for green fruit yield and its contri buting traits. These combinations may be fu rther tested for promotion ofF1 hybrids in Chilli
