The present investigation was carried out with the forty five genotypes of rice including one check, to study the nature and magnitude of genetic divergence using D2 statistics. Nineteen yield and quality traits were recorded on the genotypes in Randomized Block Design with three replications. The forty five genotypes were grouped into five clusters based on Tocher method of cluster analysis with cluster I containing the maximum of 34 genotypes. Maximum intra-cluster distance was observed in cluster I indicating greater genetic divergence between the genotypes belonging to this cluster. Gel consistency and amylose content contributed 78.79 per cent of total divergence. Maximum inter-cluster distance was recorded between clusters IV and V followed by clusters I and V indicating wide genetic diversity and it may be used in rice hybridization programme for improving the yield.Keywords

Research was carried out to determine the study of gene action and combining ability in rice. The material consisted of F2 population of 33 crosses developed by crossing genotypes with three testers. The crosses were made at RWRC, Malan during kharif 2018 and during kharif 2019 the (33) F2 materials along with parental lines (11) + testers (3) were evaluated in RBD with three replications at RWRC, Malan. Magnitude of dominance genetic variance σ2D was found to be higher than that of additive genetic variance σ2A for plant height, total tillers/plant, effective tillers/plant, panicle length, spikelets/panicle, grains/panicle, spikelet fertility, grain yield/plant, 1000-grain weight. Average degree of dominance was observed more than one for all the traits studied except days to 50% flowering, days to maturity, grain length, grain breadth and L:B ratio.Keywords
