The segregating populations of six crosses were studied in F3 and F4 generations. By using intraclass correlation and regression (F4-F3) methods, heritability and genetic correlations involving five quantitative characters were worked out. The intraclass correlation method revealed consistent estimates of heritability in F3 and F4 generations. Grain weight showed the highest heritability as against yield per plant which was the least heritable trait. The estimates obtained from regression method deviated from those obtained from intraclass correlation method. The genetic correlations in F4 revealed much stronger association among characters as compared to those seen in F3 generation. Seed yield per plant showed positive association with pods per plant and seeds per pod, and negative association with grain weight.
