Abstract

Present investigation is carried out with eight diverse genotypes of mild pungent chilli (Capsicum annuum L.) and generated twenty eight F1 crosses through 8 × 8 half diallel mating design, it was found that a lot of diversity present with respect to all the traits as depicted by scattered positions of parental arrays in the Wr-Vr graphs. The present study indicated that existence of both additive and non-additive genetic variances for inheritance of most of the traits. The graphical analysis revealed that plant height, primary branches per plant, secondary branches per plant, fruit length, fruit girth, fruit shape index, fruit weight, green fruit yield and moisture content in fruits were controlled by partial dominance. Whereas, complete dominance was observed for days to flowering and weight loss in fruits. The over-dominance played a role for the inheritance of fruits per plant, pedicel length, seeds per fruit and 100 seed weight. Moreover, the complementary type of gene interaction for the control of traits like fruit weight, 100 seed weight and weight loss in fruits in some of the parents was also observed.
