Abstract

Seventy-four rice genotypes were evaluated to assess their genetic variability, heritability and genetic advance as per cent of mean. The analysis of variance revealed significant differences for all the characters under the study except number of productive tillers per plant, indicating the presence of high genetic variability among the genotypes. The genotypes per se performance revealed BPT 3130, BPT 3164, BPT 3264, BPT 3092, BPT 3275, BPT 2824, BPT 2954, BPT 3276, BPT 3095 and BPT 3178 exhibiting significant superiority over the check Samba Mahsuri for the characters viz., grain yield per plant, test weight and panicle length. The high estimates of GCV and PCV were observed for grain yield per plant. High heritability coupled with high expected genetic advance as per cent of mean was observed for test weight and grain yield per plant suggesting that selection for the improvement of these traits may be rewarding.
