Genetic association among 11 F2 population derived from 8 parental lines of pigeonpea was carried out for 11 characters. The correlation study revealed highest positive correlation for pods per plant and branches per plant in parents and also in addition to these 100-seed weight in F2  progenies revealed that these characters may be considered for improvement of yield. Pods per plant recorded the highest direct effect on seed yield followed by pod length, seeds per pod, plant height and branches per plant while SCMR at 50 per cent flowering showed negative direct effect on seed yield.
