ABSTRACT
Twenty four accessions of muskmelon were evaluated for fourteen quantitative characters and four qualitative characters. High values of genotypic and phenotypic coefficient of variance along with high heritability and genetic advance were recorded for average fruit weight, yield per plant, total soluble solids, total sugar, reducing sugar and non-reducing sugar. On the basis of genetic divergence and relative magnitude of D2 values, all the twenty four accessions were grouped into four clusters. The maximum genetic divergence was observed between cluster III and IV followed by cluster I and III. The cluster I and II showed lowest degree of divergence. The maximum intra - cluster distance was recorded in cluster IV followed by cluster II. Cluster III recorded higher mean values for eight traits viz., node number at which first male flower appears, days to first female flower anthesis, days to first harvest, number of fruits per plant, total soluble solids, total sugar, reducing sugar and non-reducing sugar.
Key words :
Cucumis melo, Cluster pattern, D2 statistics, Genetic diversity, Muskmelon, Variability.
