dc.description.abstractIn this study, a cowpea breeding programme was set up to develop varieties with long pods that may combine early maturing and pest resistance. The strategies were to combine the early maturing characters of cultivated cowpea (Vigna unguiculata ssp. unguiculata cv-gr unguiculata) with long pod characters of yard long bean (V.unguiculata ssp. unguiculata cv-gr sesquipedalis) genotypes. Efforts were also made to cross pest resistance of wild cowpea V.unguiculata ssp. dekindtiana var. pubescensor V.unguiculata ssp. dekindtiana var.protracta with the yard long genotypes. Out of sixty one crosses attempted, only 1 success was recorded. This revealed a very low success rate of the crosses (2.94%), which is probably due to specific cross combinations, genetic divergence and environment. The only successful cross was between V. unguiculata ssp. unguiculata cv-gr unguiculata and V. unguiculata ssp. unguiculata cv-gr sesquipedalis and this was achieved when the former was used as a female parent. Morphological evaluation of the parents from the successful cross revealed that the cultivated cowpea lines had larger leaves while the long pod cowpea had conspicuously longer pods. However, the F1 seeds from the successful hybrid failed to germinate when planted for hybrid testing.en_US
