In 1988 collecting and expeditionsto Southern Africa gathered valuable genetic diversity of wild species of Virgna. A remarkable amount of variability is present in the samples of V. Unguiculata (L.) Walp. Collected in Swaziland and the Republic of South Africa. The data collected, together with ...

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...

Phenolic compounds were analysed in leaf samples from 9 lines known to be resistant or susceptible to aphids (mainly Aphis craccivora but also, to a lesser extent, A. fabae). Resistant lines TVu3000, IT84E and IT83S742 had higher flavonoid glycoside contents than the susceptible lines VITA7, TVu3...

In Italy cowpeas are grown primarily for green pod production. During 1986-88, 3 collecting missions covering the regions of Campania, Basilicata, Apulia and Calabria were mounted by the Germplasm Institute, Bari. A total of 177 seed samples were collected (147 of cowpeas and 30 of asparagus bean...

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...

Isozyme markers are commonly used to study populations, taxonomy, and the genetics of crop species. In the genus Vigna. these markers have been investigated mainly to assess genetic diversity in the V. unguiculata complex. The aim of this study was to extend isozyme analysis to other sections of ...

Thirty-two wild species and varieties of Vigna of different origin were screened for their flavotioid content. The compounds detected were utilizcd to assess both interand intraspecific relationships. Flavonoid HPLC fingerprints support evidence for the existence of different flavonoid chemotypes...
