Comparison of flowering time and embryo-genesis in four varieties of Cowpea [Vigina unguiculata (L) Walp) in a Southern guinea savannah environment

Abstract

Investigations were carried out on floweing time and embryo morphogenesis in four improved cultivars of cowpea, bred in nigeria. Observations showed significant digferences in days to cotyledon drop, days to branchingdays to flowering as well as plant height at flowering. However, flowering time and eventual maturity time suggest early, medium and late maturing genotypes amongst the experimental material.
