Cassava brown streak (CBSD) and mosaic (CMD) diseases are the major cassava production constraints in the East African region. Efforts to control these diseases were initiated in northeastern Tanganyika in the 1930’s using conventional breeding methods. Despite these efforts, CBSD is spreading, t...

Mapping of QTL associated with resistance to Cassava Brown Streak and Mosaic Diseases in outcrossing cassava cultivars locally cultivated in Tanzania
Cassava production in Africa is compromised by cassava brown streak disease (CBSD) and cassava mosaic disease (CMD). To reduce costs and increase the precision of resistance breeding, a QTL study was conducted to identify molecular markers linked to resistance against these diseases. A bi-parenta...

An improved understanding of phenotypic variation within cassava germplasm in southern, eastern and central Africa will help to formulate knowledge-based breeding strategies. Thus, the overall objective of this study was to examine the phenotypic variation in cassava germplasm available within si...

Cassava (Manihot esculenta Crantz) provides the cheapest source of food calories in Africa and forms the major staple for roughly 40% of Africans. More than 200 million people in sub-Saharan Africa derive over 50% of their carbohydrate intake from cassava. It has been recognised as a powerful pov...

Cassava brown streak disease (CBSD), caused by cassava brown streak viruses, is recognized as one of the most important plant disease threats to African food security. This study describes the incidence and severity of the different symptom types caused by CBSD, derived from extensive surveys in ...
