Abstract


A character association study involving 225 genotypes was conducted in two seasons. Seed yield was found to be positively associated with pod length, branches per plant, seeds per pod, 100-seed weight, biological yield per plant and harvest index in both the seasons, and was negatively associated with days to 50 per cent flowering, first podding and maturity in kharif season. A clear difference was observed in respect of intensity and direction of association for some traits with yield. Path analysis indicated that days to 50 per cent flowering and plant height had maximum positive direct effect on yield in summer and kharif seasons, respectively. Days to first podding and number of pod clusters per plant had a high negative direct effect in kharif season.
