Abstract:
Present investigation was carried out with 29 horsegram genotypes at Seed Unit, UAS, Dharwad, to assess genetic variability, correlation and path analysis of for seven quantitative characters. The Analysis of variance exhibited highly significant differences among the genotypes for most of the traits. Higher PCV coupled with high GCV was observed for seed yield per hectare (25.04% and 23.10%), revealing a wide range of variation for yield improvement. High heritability coupled with high genetic advance as percent of mean was observed for seed yield per hectare (85.10% and 43.91) indicating additive gene action and the ample scope for improvement in these characters through simple selection. Significant and positive correlation coefficients were recorded between number of branches per plant, plant height and number of seeds per pod; Significant and positive correlation was exhibited between pod length and number of seeds per pod whereas, significant and negative association between number of pod per plant and pod length. Seed yield per witnessed positive correlation was with all the traits except number of seeds per pod. Except number of seeds per pod (-0.7007) all other traits had recorded direct positive effect on seed yield. Residual effect (0.5785) revealed influence of other factors on yield were not considered in the model and requires further study.
