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...

The distribution and frequency of single nucleotide polymorphisms (SNPs) is an excellent tool for discerning evolutionary relatedness between cultivated and wild plant genomes. This type of information is scanty for the genus Manihot, and thus limiting systematic approaches in the genetic improve...

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...

Some genetic studies using molecular methods such as diversity assessment or marker-assisted selection require collection of a large number of samples from fields located in the vicinity or in remote areas, followed by isolation of good quality DNA in a short time span. In the present study, diff...

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(Manihot esculenta), a root crop originating in Tropical America, has been called Africa’s food insurance but vital as that is, it has the potential to be much more. Already, cassava provides more than half of the dietary calories for over 200 million people in sub-Saharan Africa (about ha...

Cassava (Manihot esculenta L.) is one of the most important food crops in the tropics, but yields are far below their potential. The gene pool of cassava contains natural genetic diversity relevant to many important breeding goals, but breeding progress has been slow, partly because of insuf-fici...

Cassava is a globally important food security and industrial crop produced for food, feed, starch and biofuel. Cassava is drought-tolerant and can grow in poor soils. Roots can be stored in the ground for long periods as part of intact growing plants, allowing flexible harvest times for poor farm...

Tanzania is the fifth largest producer of cassava in Africa, the eighth largest producer in the world with an estimated average yields of about 10.4 t/ha, which is far below the potential yield of the crop. The low yield is caused by a number of factors including susceptibility of commonly grown ...
