Journal Article 1994

Autor: Lane, J.A. Moore, T.H. Cardwell, K. Singh, B. Bailey, M.

An in vitro growth system was used to determine the virulence of two samples of Striga gesnerioides from Zakpota in southern Benin. Cowpea variety B301, previously considered resistant to all races of S. gesnerioides, was susceptible to both samples of the parasite. Two other cowpea varieties, 58...

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 ...

Autor: Jackai, L.E.N.

A laboratory screening method was developed for evaluating resistance of cowpea, Vigna unguiculata (L.) Walp, to Clavigralla tomentosicollis Stål. The technique uses dry cowpea seeds, which were judged better than fresh seeds or fresh pods, to identify protracted nymphal development and high coho...

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...

Deux virus du niébé (Vigna unguiculata), le virus de la marbrure du niébé et le virus de la mosaïque jaune du niébé, ont été étudiés. Les deux virus ont été identifiés et caractérisés à l'aide de la gamme de plantes indicatrices et de méthodes sérologiques. Les deux virus sont très répandus dans ...

Autor: Lawson, T.L. Kang, B.T.

Measurements of incident solar radiation were made in sequentially cropped maize (Zea mays L.) and cowpea (Vigna unguiculata L. Walp.) planted between hedgerows of shrubs in an alley cropping pattern. The incident solar-radiation profile was examined and its effect on crop yield determined. The s...

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...

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...
