This study sought to identify new sources of resistance to cowpea aphids (CPA) using molecular and phenotypic approaches and the inheritance pattern. Sixty cowpea genotypes were phenotyped for resistance to CPA using insect proof cages and further confirmed using markers linked to aphid resistanc...

This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...

The CIAT/CIRAD collaborative project aims to use recurrent selection to create and improve populations and gene pools containing the male-sterile gene and, from this, to develop improved lines and progenitors with traits needed by national programs. This study was to improve germplasm resistant t...
