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...

This paper is based on information collected from about 600 villages in the ten largest cassava-producing countries within the framework of the Collaborative Study of Cassava in Africa (COSCA). The objective of the paper is to show that growth in cassava production in the region will depend more ...

Participatory varietal selection work in the form of coordinated farmers' field trials involving farmers, extension agents, and researchers has been a regular component of the wheat-improvement program of Nepal since the 1970s. In this system, varietal testing is carried out in farmers' fields, b...
