Fifteen characters were investigated to study the heterosis, heterobeltiosis and inbreeding depression in parents, F1 and F2 generation of a diallel cross ( not include the reciprocal cross) involving four Capsicum annuum L. varieties. It showed that a great variation in degree of heterosis for all 15 characters. Significant heterosis occurred in fruit weight, flesh weight, total weight of fruit and total number of flower. All characteristics showed a positive direction in heterosis except days to first flower and fruit maturity. F1 hybrid exhibited heterobeltiosis over the high parent for fruit weight, flesh weight and calyx size. A considerable inbreeding depression was found in F2 generation of all characters studied and the character of total fruit weight showed the highest value.
