| Abstract | Cowpea (Vigna unguiculata (L.) Walp.) remains an important crop in the tropics. One of its challenges remains theselection and improvement of genotypes to meet locationspecific needs. We studied ten cowpea accessions in Akamkpa andIkom, Cross River State, Nigeria. Principal component and biplot analyses associated high yield with growth, flowering, pod andseed traits. Seed weight per plot and number of seeds per plot were phenotypically correlated (rp = 0.99, p ? 0.01). Number ofseeds per plot and number of seeds per pod were genotypically correlated (rg = 1.00, p ? 0.01). TVu980 did not flower atAkamkpa and TVu1019 did not grow at Ikom. TVu992, TVu53, TVu11, TVu3629 and TVu980 (only at Ikom) cowpeaaccessions showed promising agromorphological attributes for possible crop improvement programmes in Ikom and Akamkpa. |
