The path coefficient analysis showed that, the number of pod clusters per plant had the highest direct effect on seed yield. Hence, this character seems to be important contributor of seed yield and must be considered in selection for high seed yield. Whereas, the characters namely number of pod clusters per plant and days to maturity had the highest indirect effect on seed yield. Hence, the indirect selection of these traits may lead to be the development of high yielding genotypes.
