Forty advanced breeding lines including released groundnut genotypes were used to carryout path coefficient analysis for yield and component traits under terminal drought conditions. Under both normal moisture and moisture stress conditions traits viz., plant height, primary branches per plant, shelling percentage, test weight, number of kernels per plant, kernel yield per plant and fresh weight of the seedling has direct positive effect towards pod yield. However, total length of the seedlings has direct negative effect on pod yield under both the conditions. Under normal moisture condition, the secondary branches per plant, number of immature pods per plant, harvest index and number of days to maturity have direct positive effect towards pod yield. However, percentage of sound mature kernels and number of mature pods per plant recorded a negative direct effect on pod yield. Percentage of sound mature kernels and number of pods per plant has positive direct effect whereas, number of immature pods per plant, harvest index and number of days to maturity has direct negative effect on pod yield under moisture stress condition. Nevertheless, the indirect effects were negligible. This indicates that, if other characters are kept constant, an increase in matured pods per plant and total number of pods per plant will increase the yield significantly under moisture stress condition.
