Analysis of variance revealed significant differences for the traits studied except, weight of panicle and length breadth ratio of grain, indicating the existence of high genetic variability among individuals of F2 population. Less difference was observed between phenotypic coefficients of variation (PCV) and genotypic coefficients of variation (GCV) for all the characters studied, indicating absence of considerable effect of the environment. Higher value for both GCV and PCV were observed for number of effective tillers per plant, weight of panicle, number of filled grains per panicle, grain yield per plant, disease severity per cent and area under disease progress curve. High heritability with high genetic advance observed for number of filled grains per panicle, number of unfilled grains per panicle, spikelet fertility percent and area under disease progress curve hence selection will be highly effective for these traits. Number of effective tillers per plant, number of filled grains per panicle, plant height and spikelet fertility % showed significant positive correlation with grain yield per plant, thus performing selection for these traits will be resulted into improvement of grain yield per plant. Leaf blast infection cause significant decrease in grain yield per plant because both blast disease related traits (disease severity % and area under disease progress curve) in this study showed significant negative correlation with the grain yield per plant.
