Correlation, direct and indirect effect on yield and yield contributing characters in moth bean [Vigna aconitifolia (Jacq.)]

Abstract

A field experiment entitled “Genetic diversity in moth bean [Vigna aconitifolia Jacq.)] was conducted at Agricultural Botany Research Farm, College of Agriculture, Pune during Kharif 2018. 30 genotypes were obtained from Dry and Agricultural Research Station, Solapur. The experiment carried out in randomized block design with three replications. The seed yield per plant showed significant and positive relationship with peduncle length followed by number of clusters per branch, number of seeds per pod, secondary branches per plant and primary branches per plant at the genotypic level. The seed yield per plant showed significant and negative correlation with days to 50 per cent maturity (-0.2843) and days to maturity (-0.4161). In present study, the character peduncle length showed highest direct positive effect on seed yield per plant followed by secondary branches per plant, clusters per branch, days to 50 per cent flowering, seeds per pod (0.1315). Thus, direct selection for these traits will be beneficial in yield improvement programme.
