Cowpea is the most important grain legume and fodder crop in the dry savannas of Africa. Grown on more than 12.5 million hectares, grain yields from improved varieties are higher than local varieties, but require 2 to 3 insecticide sprays to control major pests compared to local varieties. Losses...

Yams (Dioscorea species of family Dioscoreaceae) are important for food, income, and sociocultural activities especially in West and Central Africa and account for about 93% of the world’s annual production of 38 million tonnes. Breeding of yams is focused primarily on the two dominant species, D...

Reliable characterization of the variation among wild and cultivated yams in Nigeria is essential for improved management and efficient utilization of yam genetic resources. RAPD and double stringency PCR (DS-PCR) analyses were used to investigate genetic relationships and the extent of redundanc...

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...

This paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western Kenya. The results showed that women are as technically and allocatively efficient as men. However, neither men nor women have absolute allocative efficiency. Women farmer...

The ploidy levels of the twenty-two yam (Dioscorea cayenensis-D. rotundata complex) cultivars within germplasm Cameroon Guinea yam were determined by flow cytometry. Three different ploidy levels (4x,6x, 8x) were detected within the samples analysed. Fifteen cultivars were tetraploids, five were ...

DNA from twenty-three late maturing cultivars of Guinea yams (D. cayenensis/D. rotundata complex) from the Benin Republic that could not be separated using isozyme markers, were examined using randomly amplified polymorphic DNA (RAPD) markers with decamer primers of arbitrary sequence. All the tw...
