Interspecific hybridization between Vigna unguiculata and V. vexillata always failed: no seed was obtained in both crossing directions. Two different barriers to crossability were found: a pre-zygotic barrier and a post-zygotic one. Many abnormalities were observed in pollen-tube development, whi...

Cowpea (V. unguiculata) represents the main food legume in tropical Africa. Germplasm collecting missions launched over the past 10 years have provided genebanks with a wide array of variability within the cultivated and wild taxa of the species. Based on detailed studies on morphological diversi...

The responses of 24 white yam (Dioscorea rotundata) cultivars to mechanical and vector transmission with each of three viruses infecting yams were assessed through enzyme-linked immunosorbent assay (ELISA) and symptom development. The viruses were Dioscorea alata virus (DAV), genus Potyvirus; Dio...
