Abstract: Among 10 rice grain quality traits studied, phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits. High heritability (71 - 98) was found for all the traits. High heritability with high genetic advance was found for kernel L/B ratio (92 & 25.26), cooked kernel length (93 & 21.77) and alkali digestion value (98 & 43.48). Different rice grain quality traits were interrelated. Among various traits that were interrelated, strong association was found between kernel length and kernel length/breadth ratio (r=0.96) and hulling and milling recovery (r=0.91). Cooked kernel length was associated with most of the grain quality traits that could be given preference in selection criteria for improvement of multiple grain quality traits simultaneously.
