Abstract
The current research was aimed for estimation of variability parameters, heritability, genetic advance, skewness, kurtosis, association and path coefficient analysis for twelve traits using F2 population attained from the cross ADT (R) 48 x Kavuni. High GCV and PCV, higher range of heritability adjoined with eminent genetic advance as per cent of mean besides significant positive skewness for the characters namely; the number of tillers per plant, the number of productive tillers per plant, the number of grains per panicle, the number of filled grains per panicle and single plant yield was observed indicating the predominance of cumulative gene effect and an effective selection. High positive direct impact with strong positive correlation on single plant yield was observed in the traits, the number of tillers per plant and the number of filled grains per panicle perhaps to be considered as useful traits in yield improvement. The information obtained from the current study may be advantageous in the selection and for the advancement of yield in future rice breeding programs. Key words: Rice, genetic variability, path analysis, skewness and kurtosis
