ESTIMATION OF GENE ACTION FOR YIELD AND ITS CONTRIBUTING TRAITS IN BITTER GOURD (MOMORDICA CHARANTIA L.)

The present experiment was carried out to assess gene action in fifty-four genotypes comprising 15 parents and their fifty crosses through line tester method.Analysis of variance exhibited significant differences among the genotypes for all the traits under studied.The data was collected for various morphological characters associated with yield and its contributing traits.In reference to estimates of additive variances ( 2 A) was lower than dominant variance ( 2 D) for different attributes all characters such as number of male flowers per pant, fruit weight, first fruit harvest, number of female flowers per plant, days to first fruit set, vine length, number of days to open first female flower, number of seeds per fruit, fruit length, number of days to open first male flower, number of fruits per plants, 100 seed weight, number of primary branches, fruit diameter, total soluble solids, sex ratio and fruit yield per plant .indication the presence of additive gene action.
