Abstract:

Blackgram (Vigna mungo L. Hepper) is one of the important pulse crops in India. The present study was aimed to study the inter-relationship between yield and among related traits in inter sub-specific derived lines of blackgram. Correlation analysis revealed that significant positive association was observed in pods per plant (0.89), clusters per plant (0.74), plant height (0.62), primary branches per plant (0.52), hundred seed weight (0.52), seeds per pod (0.51) and pod length (0.49) with single plant yield at the genotypic level. At the phenotypic level, pods per plant (0.88), clusters per plant (0.69) and plant height (0.54) with a single plant yield. Clusters per plant (0.630), seeds per pod (0.625) and hundred seed weight (0.366) had a positive direct effect on single plant yield. Plant height (0.253) and pods per plant (0.202) had a moderate positive direct effect on single plant yield. Pod length (0.137) and 50 percent flowering (0.106) had a low positive direct effect on single plant yield. Plant height, clusters per plant, pods per plant, seeds per pod and hundred seed weight had a high influence on single plant yield. Hence, emphasis could be given to the above traits during selection for the improvement of yield in blackgram.
