Description M. Sc. (Ag.)
The present investigation entitled “Studies on genetic variability among different genotypes of bitter gourd (Momordica charantia L.)” was carried out at the Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U.P.), during Kharif season of 2015. The experiment was conducted in Randomized Block Design (RBD) involving eighteen diverse genotypes of bitter gourd with three replications. The data on nineteen characters namely days to first male flower anthesis, days to first female flower anthesis, node number at which first male flower appears, node number at which first female flower appears, days to 50% female flowering, vine length (m), number of primary branches per plant, internodal length (cm), fruit length (cm), fruit girth (cm), fruit diameter (cm), average fruit weight (g), number of fruits per plant, marketable fruit yield per plant (kg), number of seeds per fruit, seed weight per fruit (g), seed yield per plant (g), leaf chlorophyll content (nmol/cm) and TSS of fruit (0brix), were recorded from five plants randomly selected for each genotypes. On the basis of result of this investigation, it is concluded that out of 18 genotypes, OBGCS-4 showed maximum value for number of fruits per plant. On the basis of days to first male flower anthesis, number of days to first female flower anthesis, node number at which first male flower appears and node number at which first female flower appears genotypes such as Local Germplasm-2, IC-085612 and Local Germplasm-4 were considered to be earliest among all the genotype. Based on the genotypic and phenotypic coefficient of variation, seed yield per plant, marketable fruit yield per plant, average fruit weight, seed weight per fruit, fruit length showed high magnitude of variability in these characters. High heritability along with high genetic advance was observed for fruit yield per plant, average fruit weight, fruit length, fruit girth, node numbers at which first male flower appears which indicated that these characters were more reliable for effective selection for improve the yield of bitter gourd. The magnitude of genotypic correlation coefficient and phenotypic correlation coefficient revealed that characters like vine length, fruit diameter, fruit length, seeds per fruit, days to 50% female flowering, internodal length and primary branches per plant could be considered as criteria for selecting high fruit yielding genotypes of bitter gourd. Path coefficient analysis, at genotypic and phenotypic levels revealed that the characters namely, average fruit weight, number of fruits per plant, fruit girth, fruit length, weight of seeds per fruit, days to 50% female flowering and internodal length had direct, strong and positive effect on marketable fruit yield per plant. Thus these traits could be used for selection of high marketable fruit yield.
