Genetics of capsaicin content in chilli (Capsicum annuum L.)

1984

REP.PP-0098

Two varieties of chillies, viz. Perennial (pungent) and Kaloscai E-15 (non-pungent) were used to study the inheritance of capsaicin in chilli by utilizing a basic set of six generation. The cross between Kaloscai E-15 and Perennial was made during 1979, the F2 and backcross generations were produced during 1980. The six basic generations, viz. P1, P2, F1, F2, B1 and B2 were sown in nursery. The number of plants allocated to different generations were: P1=P2=F1=20, B1=B2=50 and F2=100. The mean value of F1 was slightly more than the mid-parent value which indicated partial dominance of pungency over non-pungency. The simple additive dominance model failed for capsaicin content with X2 3df value of 20 59 (P < 0.01) indicating the presence of epistatic factors. [PLH]
