Journal Article 1990

Autor: Piergiovanni, A.R. Della Gatta, C.D. Ng, N.Q. Singh, B.B. Singh, S.R. Perrino, P.

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...

Autor: Bata, H.D. Singh, B.B. Singh, S.R. Ladeinde, T.A.O.

Aphid (Aphis craccivora Koch) is a major pest of cowpea [Vigna unguiculata (L.) Walp.] particularly in the drier regions of the tropics. It causes direct damage by feeding on the plants and also transmits viruses. Several sources of resistance to cowpea aphid have been identified and efforts are ...
