Abstract:

Fifty-six diverse genotypes of cucumber collected from different indigenous sources were planted in randomized block design, during kharif season at Kittur Rani Chennamma College of Horticulture, Arabhavi, Belagavi district (Karnataka), India. Genetic diversity study using Mahalanobis’s D2 statistics with Tocher’s method, 56 cucumber genotypes were grouped into ten clusters, cluster I was the largest having 26 genotypes followed by cluster III (10 genotypes) followed by cluster II (six genotypes). Among ten clusters, cluster VIII with two numbers of genotypes had maximum intra cluster distance followed by cluster V and Cluster VII. Based on the distance between the clusters i.e., inter-cluster distance, maximum divergence was observed between cluster IV and VIII, followed by Cluster IV and IX, this indicated wide range of variability among clusters. Among 18 characters studies in D2 analysis fruit yield per hectare (22.34 %) contributed maximum towards expression of genetic divergence followed by average fruit weight (17.21 %), number of fruits per vine (14.09 %), number of branches per vine (9.42 %) and days to first harvest (9.22 %). On the basis of intercluster distance and per se performance observed in the present study a hybridization programme involving genotypes for a specific character be chosen using cluster mean.
