Ten varieties of forage cowpea were evaluated for stability parameters with respect to seed yield and its components in eight environments. The varieties included were FOS 1, HFC 42-1, GFG 2, GFC3 GFC 4, UPC, 9020, EC 4216, C 152, C 1 and 82-1-B. Presence of genotype environment interaction was observed. The linear component appeared to account for most of the interactions present. Three parameters of stability were positively associated in the case of pods per plant and 100 seed weight. Based on these results GFG 3 was found to be the most stable variety for seed yield. Its stability was mainly due to higher number of pods. Breeding for higher number of pods and 100 seed weight with greater stability is advocated.
