Genetic diversity studies in selected elite genotypes and released varieties of Rice

An experiment was undertaken by utilizing fifty selected elite genotypes and released varieties of rice for ten yields yield contributing characters to assess genetic divergence at Zonal Agriculture Research Station, Igatpuri, Dist. Nashik during kharif-2020. Path coefficient analysis revealed that test weight exhibited highest positive direct effect on grain plant-1 subsequently spikelet fertility, number panicles plant-1, plant height, panicle-1, panicle length days physiological maturity. Whereas, fertile panicle-1 recorded the negative plant-1. The viz; had exerted significant correlation these with positively significant. Fifty were grouped into eight clusters. Cluster II biggest consisted 19 followed cluster I 11 genotypes. III V both consist 8 All remaining clusters viz. IV, VI, VII VIII solitary. Intra distance ranged from zero (cluster VIII) 13.15 V). intra observed in III, I. From inter D2 values clusters, it can be seen occurred between VI suggesting crosses involving would give wider desirable recombination. Keywords:-Cluster, correlation, diversity, Rice
