Correlation and path coefficient analysis in blackgram [Vigna mungo (L.) Hepper]

Abstract

Fourty five blackgram genotypes were studied including two check varieties (Pratap Urd-1 and PU-31) in randomized block design with three replications to study correlation and path coefficient analysis for 14 traits. Seed yield per plant was positively and significantly correlated with number of branches per plant, number of clusters per plant, number of pods per plant, number of pods per cluster, biological yield and harvest index at both phenotypic as well as genotypic level. The positive direct effect on seed yield per plant was exhibited by number of pods per plant, biological yield, harvest index, days to 50 per cent flowering, plant height and number of seeds per pod. Thus, seed yield per plant can be improved by practicing selection for number of pods per plant, biological yield, harvest index, days to 50 per cent flowering, plant height and number of seeds per pod.
