Genetic Diversity Characterized

We extended our study of the genetic diversity of cassava landraces, using microsatellites, to assess the genetic diversity and differentiation of cassava landraces from five countries in South America, three in Central America, and four in Africa; and also to African cassava genotypes resistant to cassava mosaic disease (CMD). Analysis showed substantial genetic diversity in CMD resistance, with appropriate germplasm available for the genetic improvement of CMD resistance, as well as other traits, particularly yield. The study of genetic diversity in Tanzania, Nigeria, Uganda and Ghana revealed a broad and unique diversity of local land races that can serve as the basis for a breeding program.

The above results have been placed on the The Cassava Molecular Diversity Network (MOLCAS) Web Site and are available to the Cassava Community.
