Abstract:

The genetic diversity among thirty six genotypes of pointed gourd was assessed from an experiment conducted at Vegetable Research Centre of G.B.P.U.A & T., Pantnagar during summer-rainy season, 2015. Thirty six genotypes of pointed gourd were grown in Augmented Block Design II with three checks (Kashi Alankar, Swarna Rekha and Rajendra Parwal-1). All the thirty nine genotypes of pointed gourd were classified into seven non-overlapping clusters on the basis of D2 analysis and maximum inter-cluster distance were found between cluster VII and IV (72.42). This indicates that inter genotypic crosses between the members of cluster VII and IV would exhibit high heterosis and is also likely to produce new recombinants with desired traits. High cluster mean value for total soluble solid (4.13), number of primary branches (8.46), vine length (7.74) and nodes per vine (77.45) were presented in cluster III, however cluster I perceived genotypes with highest mean value for fruit length (9.35), fruit dry matter (7.24). Among the various traits studied, number of fruits per plant contributed the maximum (84.48%) towards divergence. A total of eight principal components were identified with principal component analysis which accounts 83.63 per cent of total variation.
