Correlation and path coefficient studies in Blackgram ( Vigna mungo (L.) Hepper)

Abstract

In the present investigation, twelve characters including quantitative and qualitative were evaluated in 29 genotypes of blackgram during Kharif 2016 to assess the correlation and path analysis. The genotypes differed significantly for all the characters studied. Seed yield per plant was positively and significantly correlated with number of branches per plant, number of pods per plant, biological yield per plant and harvest index at both phenotypic as well as genotypic levels. The characters number of branches per plant, number of pods per plant, biological yield per plant and plant height exerted high positive direct association with seed yield. Number of branches per plant and biological yield per plant showed highly positive indirect effect through on seed yield. Hence, selection based on number of pods per plant, number of seeds per pod and hundred seed weight would result in improving the seed yield of blackgram.
