Abstract:
The investigation entitled “Genetic Studies in Bitter Gourd (Momordica charantia L.)” was undertaken during summer 2020 and kharif 2020 by following genetic studies to obtain information on gene effects, heterosis, general and specific combining ability and heritability for various quantitative characters. The additive and additive x dominance effects were equally important in some combination for most of the characters. Dominance x dominance gene effects were greater magnitude followed by additive x additive and additive x dominance for node at which first female flower appeared, days required for first harvest of fruit, fruit length, fruit weight, respectively in both summer and kharif season. High percentage of heritability was observed in the most of the characters like vine length, days required for initiation of male and female flowering, number of female flowers per vine, node at which first female flower appeared, days required for first harvest of fruits, yield per vine, weight of fruit, length of fruit, diameter of fruit, weight of seed per fruit, downey mildew, powdery mildew, fruit fly and leaf miner. It indicated that, most likely the heritability is due to additive gene effects and selection may be effective.
