Substantial genetic variability among the all genotypes was observed for the characteristics under study. All the genotypes were showed highly significant differences for all the studied grain quality traits. Coefficient of variation ranges from 8.61% for hulling percentage to 45.01% for alkali spreading value. Negligible difference between genotypic coefficient of variation and phenotypic coefficient of variation was observed for all the traits. High heritability with high genetic advance as percent mean was observed for all the grain quality traits except for hulling percent and milling percent. These results indicated that direct selection based on phenotypic performance could be rewarding for all quality traits because they are less influenced by environment and mostly governed by additive gene action. It has been observed that sixty nine genotypes had short slender type grain characteristics whereas; forty seven genotypes have short bold type grains. Thirty genotypes showed more than 80% hulling percent, fifty six genotypes showed more than 70% milling percent and fourteen genotypes showed more than 65% * Corresponding author KEYWORDS Rice Landraces Grain quality Genetic variability Amylose content E-mail: deepakhybridrice@gmail.com (Deepak Sharma) Peer review under responsibility of Journal of Experimental Biology and Agricultural Sciences.
