Abstract:

The genetic diversity estimation was carried out in sixty seven germplasm of rice using Mahalanobis D2 by considering 32 yield and quality characters. ANOVA revealed the presence of considerable amount of variability among the genotypes studied. Thousand (1000) grain weight contributed 47.76% of total genetic divergence followed by grain length (15.88%) and Number of spikelet per panicle (8.01%).It also manifested that genotypes were grouped into twelve clusters. Cluster I, III, V and VIII containing maximum genotypes with highest intra-cluster distances. While, clusters IX and X (D2= 13160.30) followed by VIII and IX (D2=9440.02) as well as VII and X (D2 =5965.22) were highly diverse from each other as these clusters showed maximum inter-cluster distance. Hence, genotypes belonging to these clusters could be chosen as parents in hybridization programme Genotypes Madhuri, DhaniyaDhan, NPT 14-6, LalJeera, Kalimuch, Mohan Bhog, Tarori Basmati and Padma reported as most divergence and chances of finding the desirable recombinants after hybridization could be more.
