With a purpose to increase the effect of selection in bitter gourd (Momordica charantia L.), four inbred lines were crossed for a diallel cross set, and grown in the green house. The characters investigated were fruit length, fruit width, fruit weight, number of fruit, thickness of fruit flesh, days to maturity (from flowering), seed length, seed width, seed weight, number of seed per fruit, ovary length, ovary width, ovary weight, peduncle length, and yield. Correlation coefficient analysis revealed that six characters i.e. fruit weight, fruit length, ovary length, peduncle length, seed width, and yield showed highly positive correlations. Among 15 characters, eight characters, such as ovary length, ovary width, ovary weight, seed length, seed width, seed weight, number of seed, and peduncle length, showed partial dominance in vr-wr graph analysis, but they showed different degree of dominance. Ovary length, seed length, seed width, and seed weight were controlled by additive rather than dominant effect of genes, and they had very high heritabilities in both broad and narrow sense, while in ovary weight, ovary width, and peduncle length, additive effect of genes was similar to dominant effect. Number of seed per fruit was governed by dominant rather than additive effect of genes. Heritabilities (h** (2)N) in the narrow sense were low or moderate for number of seed, ovary width, and ovary weight, and that of peduncle length was high
