GENETIC DIVERGENCE IN MID EARLY GROUP GENOTYPES OF RICE ( Oryza sativa L.)

摘要

Sixty four mid early group genotypes of rice were studied for genetic diversity for yield and yield contributing characters. Cluster analysis revealed sixty four genotypes were grouped into 11 clusters. The pattern of distribution of genotypes into different clusters was at random. Plant height contributed maximum towards genetic divergence followed by days to 50% flowering. The maximum inter cluster distance observed for between 4 and 7 (182.08) followed by cluster 1 and 4 (169.94). The genotypes from these clusters can be utilized in hybridization programme for improvement of rice.
