Cassava is an ideal vehicle for delivering provitamin A carotenoids to human populations affected by deficiency of this important micronutrient. Rapid cycling recurrent selection has proven to be very effective increasing carotenoids levels in cassava. The maximum level of total carotenoids incre...

Multilocational trials were conducted in several agroecological zones in West Africa to assess the magnitude of genotype x environment (G x E) interaction and to identify stable varieties which could be used in breeding programs in the region. The reaction of the varieties to major cassava diseas...

Yam production is constrained by the limited availability and high cost of quality seed due to its slow vegetative propagation ratio. Micropropagation using nodal and meristem explants have been used to produce clean plantlets, with a 1:4 multiplication ratio for nodal explants and 1:1 ratio for ...
