Abstract:
The present investigation entitled “Genetic studies in Bitter gourd (Momordica charantia L.)” was undertaken during summer and kharif 2020-2021 by following generation mean analysis to obtain information on gene effects, heritability and genetic advance for various quantitative characters. Three possible crosses involving four parents (RHRBG-26, RHRBG-24, RHRBG-10 and RHRBG-29) with six generations (P1, P2, F1, F2, BC1 and BC2) for each of these crosses were evaluated in randomized block design with two replications during summer 2021 at the All India Coordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). All three types of gene actions viz., additive, dominance and epistasis (i, j and l) were present in most of the combinations for almost all characters under study and these characters can be improved by reciprocal recurrent selection. Duplicate type of epistasis were observed in all crosses for number of branches per vine, length of vine, days to first picking, days to last picking, length of fruit, weight of fruit, fruit fly and some crosses also showed duplicate type interaction in some remaining characters.

Complementary type epistasis was observed in the cross 2 (RHRBG-26 x RHRBG-10) days to appearance first male flower, node number at which first female flower appeared, days to 50% flowering, number of fruits per vine, fruit yield per vine, fruit yield per plot, fruit yield and downey mildew; cross 3 (RHRBG-26 x RHRBG-29) for days to appearance first male flower, days to 50% flowering, number of male flowers per vine, number of female flowers per vine, sex ratio and downey mildew in summer seasons and cross 1 (RHRBG-26 x RHRBG-26) for number of female flowers per vine, node number at which first male flower appeared, diameter of fruit, number of fruits per vine. The additive and additive x dominance effects were equally important in some combination for most of the characters. The heritability (broad sense) and genetic advance estimates were high for most of the characters.
