Abstract:
Ten lines of bitter gourd (Momordica charantia L.) were crossed each with four testers in line x tester mating design. The resultant 40 hybrids along with the parents were evaluated in randomized block design with two replications at Vegetable Science unit, College of Horticulture, Bagalkot. Combining ability analysis revealed importance of both additive and non-additive gene action. On the basis of overall performance the line L10 was found good combiner for majority of the characters (number of nodes up to first female flowering, days to first harvest, number of fruits per vine, average fruit weight, fruit length, fruit girth and fruit yield per vine). L10 x T1 exhibited high sca effects for nodes up to first female flowering, fruit maturity to fruit set and fruit yield per vine. The cross L3 x T2 exhibited high sca effects for fruit length, fruit yield per vine and days to last harvest. These crosses were also found to show significant heterosis in the desired direction for most of the yield characters. Hence they can be exploited as desirable hybrids.
