Reports the findings of a mission carried out by the International Institute of Tropical Agriculture in Zimbabwe to gather genetic resources of cowpea, rice, bambarra groundnut and their wild relatives. 461 samples of 365 species were collected. Sampling was made over 140 sites of both natural ve...

Screening germplasm of Vigna vexillata for resistance to cowpea mottle virus
Fatty acid composition of extracted oils from 58 lines of cowpea (Vigna unguicuiata (L) Walp) was investigated by gas‐liquid chromatography (GLC). Considerable variability was observed in the fatty acid profile, though palmitic (16:0), linoleic (18:2) and linolenic (18:3) acids were the dominant ...
Trypsin inhibitor content was determined in the seeds of 21 cowpea (Vigna unguiculata) lines (10 known to be resistant to Callosobruchus maculatus and 11 susceptible) whilst fatty acid composition was determined in 58 lines (11 resistant and 47 susceptible). A wide range in trypsin inhibitor cont...
Data are given on seed characteristics and nutritive value for 6 accessions of 4 wild Vigna taxa (V. vexillata, V. oblongifolia, V. gracilis and V. unguiculata subsp. dekindtiana) and 27 cultivated V. unguiculata varieties. The 100-seed weight ranged from 2 to 6 g among wild and from 6 to 24 g in...

Trypsin inhibitor levels in raw and cooked cowpea (Vigna unguiculata) seeds
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...

Origin, taxonomy and morphology of Vigna unguiculata (L.) Walp
The genus Vigna comprises seven subgenera and sixteen sections. Cowpea, Vigna tingnicnlatti (L.) Walp.. is an important grain legume crop in sub-Saharan Africa and belongs to the subgenus Vigna. section Ctitiang. Morphologically, cowpea genotypes appear very variable. However, a high level of gen...
Flavonoid chemical markers together with other biochemical markers and/or morphological data can provide useful characters for defining species in Vigna genus. In this paper flavonoid HPLC fingerprints have been utilized to assess taxonomic relationships amongst species and accessions of Vigna.Wi...
