Summary: | The present investigation was carried out to explore the extent of divergence, correlation and path analysis in 77
rice genotypes for twelve characters during Rabi, 2021. Ten clusters were formed by Mahalanobis’ D2 analysis of
which cluster I was the largest with 28 genotypes. Cluster IV and IX were the smallest with one genotype each. The
maximum intra-cluster distance was observed between cluster X and the maximum inter-cluster distance was between
clusters VIII and X. The days to 50 % flowering contributed to the maximum divergence. Superior mean performance
for grain yield per plant was recorded in cluster IX. The grain yield per plant was found to be positively correlated with
the days to 50 % flowering, the total number of tillers, the total number of productive tillers, panicle length, leaf width,
the total grains per panicle, filled grains per panicle and spikelet fertility. Path analysis results revealed that the total
number of productive tillers, leaf width, filled grains per panicle, days to 50% flowering, the total grains per panicle
and spikelet fertility had a positive direct effect with grain yield. The selection should be done for these traits for yield
improvement.
