Abstract:
The present investigation was carried out to study genetic parameters for eleven seed yield and its physiological quality contributing characters in thirty rice genotypes with three check varieties during Kharif 2016. Analysis of variance showed significant differences among all the characters under study. The phenotypic coefficient of variance was slightly higher in magnitude than that of genotypic coefficient of variance for seed yield and its physiological contributing characters indicating very less environmental influence on the expression of these traits. Higher genotypic coefficient of variation was recorded for seeds per panicle (24.22) followed by seed yield per plant (22.14) and vigour index (18.31). Heritability in broad sense estimates were higher for days to 50% flowering followed by seedling dry weight, days to maturity, plant height, vigour index and seed yield per plant. High expected genetic advances were observed for characters viz., seed yield per plant, seeds per panicle, vigour index, plant height, days to 50% flowering and seedling dry weight. High heritability along with high genetic advance as percent of mean was registered for days to 50% flowering, seedling dry weight, plant height, vigour index and seed yield per plant, this suggest that these traits can be taken as selection parameters to select elite genotypes.
