Abstract:
The experiment was conducted during the spring-summer season, 2017 in Eastern Uttar Pradesh, to evaluate the nature and magnitude of genetic divergence among the thirty genotypes of bitter gourd were carried out by using Mahalanobis D2 statistics. Thirty genotypes were grouped into 7 different non-overlapping clusters. The highest number of genotypes was presented in cluster III which contained 9 entries followed by cluster V which contains 8 entries, cluster VI which contained 5 entries, cluster I which contained 4 entries, cluster IV which contained 3 entries and cluster II possess 1 entries respectively. Highest estimates of genetic advance in per cent of mean was recorded for vine length (80.31%), node number to anthesis of first staminate flower (66.23%), number of fruits per plant (45.65%), total fruit yield/plant (38.42%). Moderate genetic advance in per cent of mean was estimated in number of primary branches per plant (37.86%), node number to anthesis of first staminate flower (37.65%), fruit length (37.40%), number of nodes per vine (35.35%), average fruit weight (31.68%), fruit diameter (29.79%) whereas days to anthesis of first pistillate flower (26.12%), days to anthesis of first pistillate flower (23.80%), days to first fruit harvest (21.58%) showed low genetic advance in per cent of mean. Vine length contributed maximum towards genetic diversity (26.67%), followed by fruits per plant (25.75 %), days to anthesis of first pistillate flower (13.69%), average fruit weight (9.43%), number of primary branches per plant (8.51%), node number to anthesis of first staminate flower (7.36%), fruit length (4.37%) and total marketable fruit yield per plant in sponge gourd.
