Association analysis in black gram (Vigna mungo (L.) Hepper)

Correlation coefficient and path analysis studies conducted with ten parents and their twenty five hybrids revealed that primary branch number, cluster number, pod number, pod length and seed number per pod had strong positive association with yield. Besides, their inter correlations were positive and significant, indicating the possibility of improving these characters simultaneously. The path analysis indicated that the contribution of pod number followed by seed number per pod and primary branch number was much through direct effects and their indirect effects by way other traits were also much pronouncing. Seed protein had no association with any of the other characters and its direct effect on yield was also less.
