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...

Shoot cultures of 401 banana clones were conserved under slow growth conditions (16±1°C, 25μmol m−2 s−1). Storage duration-defined as 60% survival time of 20 shoot cultures of a clone-averaged 334 days. However, large differences occurred among the different genomic (sub)groups and even within th...

An agroecologically-based germplasm enhancement strategy to further broaden the genetic base of cassava in selected ecologies of Africa was initiated by CIAT and IITA in 1990. Crosses are being made at CIAT, in Colombia, using parents adapted to four different agroecologies of South America with ...

Water logging is a potential abiotic stress problem in the warm tropical potato growing areas, particularly in the lowland rice-based cropping systems. A field experiment was conducted in San Ramon, Peru during the rainy season to evaluate the effects of water logging on 12 clones (8 lowland trop...

An Agrobacterium-mediated transformation protocol was tested using eight clones of Musa with different ploidy and genomic background. These were selected to represent several major groups of Musa including dessert and highland bananas (AAA), cooking bananas (ABB), improved plantain hybrids (AAB X...

La marchitez bacteriana (MB) o pudricion parda causada por Ralstonia solanacearum es una de las enfermedades bacterianas mas destructivas en el cultivo de la papa. La resistencia de las plantas es el medio mas efectivo para controlar esta enfermedad. Sin embargo, la resistencia a la MB es a menud...
