The research work was undertaken in Kharif, 2019 at Department of Seed Science and Technology, College of Agriculture, PJTS Agriculture University, to identify lines with good vigour and high yield. Analysis of variance revealed existence of significant differences among the genotypes. Dry weight of seedling followed by seedling vigour index-II had showed high PCV and GCV. Germination (%) -first count, length of shoot, length of root, dry weight of seedling, seedling vigour index-I, seedling vigour index-II and field emergence exhibited high heritability along with high genetic advance as per cent of mean. Length of seedling, seedling vigour index-II and germination (%) -first count exhibited the high positive direct effect on per plant grain yield. Among all the traits Seedling vigour index-II and dry weight of seedling has shown high variability, correlation and cause effect analysis. Therefore, these traits have to be given importance during selection process for identification of high vigour rice lines.
