Abstract

The experiment was comprised of 55 crosses of wide hybrids of grasspea intergeneric with pea genotypes and interspecific crosses with three species viz., sativus, cicera and odoratus of grasspea. The analysis of variance revealed highly significant for eleven characters out of fourteen characters at 1% level of significance The remaining three characters viz., Number of primary branch per plant, pod length and pod breadth showed significant only at 5 % level of significance. The highest PCV and GCV was recorded for ODAP content (84.29, 84.19), Days to maturity (54.18, 53.40), seed yield per plant (53.24 , 52.73), seeds per plant (52.44 , 52.27), Pods per plant (45.91, 45.64), seed index (44.09, 43.94), Secondary branch per plant (36.27, 35.37), seeds per pod (32.14, 31.69), Pod length (26.43, 26.39) and Primary branch per plant (23.72, 21.53), high heritability coupled with high genetic advance as percent of mean was recorded for the characters ODAP estimation (99.75 %, 97.64)

Conclusion

The analysis of variance showed a wide range of variation and significant difference for all the traits under research work with the sufficient amount of variability. The highest PCV and GCV was recorded for ODAP content, Days to maturity, seed yield per plant, seeds per plant, Pods per plant, seed index, Secondary branch per plant, seeds per pod, Pod length and Primary branch per plant. The genetic variability showed less influence of environment on the expression on traits. The heritability was recorded higher for all the fourteen characters. High heritability coupled with high genetic advance as percent of mean was recorded highest for the characters ODAP estimation followed by Seeds per plan, Seed Index, Days to 50 percent flowering, Seed yield, Seeds per pod, Days to maturit, Pod length, Days to first flowering, Pods per plant, Pod breadth, Secondary branch per plant and Primary branch per plant, it indicates that these traits are under the influence of additive gene ac
