Factors responsible for successful rescue of immature embryos of cowpea [Vigna unguiculata (L.) Walp.] and V. vexillata (L.) and for in vitro embryo development were studied. A new basal medium for embryo development in vitro was formulated on the basis of the mineral composition of embryos. Sucr...

A knowledge of the extent of genetic variation in a crop is a prerequisite for its improvement. In cassava (Manihot esculenta Crantz) such knowledge is lacking especially at the DNA level. The genetic variation among 28 cassava varieties collected from different locations in the Republic of Benin...

La connaissance de l'importance de variation genetique chez une culture est necessaire pour son amelioration. Chez le manioc (Manihot esculenta Crantz), une telle connaissance manque surtout au niveau du DNA. La variation genetique parmi les 28 varietes du manioc recueillies de differentes locali...

Between 1991 to 1996, more than 50 Musa hybrids and 10 landraces were evaluated under field and screenhouse conditions for virus symptoms resembling those caused by banana streak badnavirus (BSV). The symptoms included chlorotic streaks, leaf deformation, stunting, cigar leaf death, distortion of...

Insecticidal lectins were isolated from 20 resistant Vigna and non‐Vigna legumes and tested againstn 3 pests of cowpea namely: Maruca vitrata, Callosobruchus maculatus and Clavigralla tomentosicollis. Crude lectins were separated from seeds using sodium chloride extraction, ammonium sulfate fract...
