The F2 segregating generation of two crosses viz., CO 52 × CR Dhan 310 and RNR 15048 × CB 13543 were evaluated for variability parameters, character association and path coefficient analysis. The results revealed that both the crosses exhibited high GCV and PCV for the traits viz., number of productive tillers per plant, number of filled grains per panicle and single plant yield. The traits viz., number of productive tillers per plant, number of filled grains per panicle, hundred grain weight and single plant yield showed high heritability coupled with high genetic advance indicating the presence of additive gene effect and selection for these traits may be effective. Correlation studies revealed that plant height, number of productive tillers and panicle length had significant positive association with single plant yield in both crosses. Number of productive tillers per plant showed high positive direct effect on grain yield. Path analysis revealed that number of productive tillers per plant showed high positive direct effect on grain yield. |
