Genetic variability, correlation studies, path coefficient analysis and genetic divergence in horsegram (Macrotyloma uniflorum (Lam.) Verdc.)

A field experiment was undertaken to evaluate the variability and performance of thirty horsegram genotypes collected from various regions Kerala outside for yield attributing characters. Analysis variance carried out based on recorded observations, it showed significant differences among 30 all fifteen characters studied. Most traits exhibited narrow between PCV GCV except seeds per pod, number primary branches plant plant. Yield found be positively correlated secondary plant, nodes pod 100 seed weight both at phenotypic genotypic levels. Path analysis revealed that days maturity were major contributing owing their favorable direct effect Genetic diversity studies using Mahalanobis’ D2 statistics assembled into eight clusters.
