A study was conducted to determine the extent of genetic diversity among African cassava (Manihot esculenta Crantz) accessions resistant to the cassava mosaic virus disease (CMD), using simple sequence repeat (SSR) markers. The accessions included a breeding stock (clone 58308), five improved lin...

Assessment of genetic diversity among African cassava Manihot esculenta Grantz accessions resistant to the cassava mosaic virus disease using SSR markers
Cassava mosaic disease (CMD) is the most-important disease of cassava (Manihot esculenta) in Africa, and is a potential threat to Latin American (LA) cassava production. Although this viral disease is still unknown in LA, its vector – the whitefly – has recently been found. The disease is best co...

Genetic mapping of a dominant gene conferring resistance to cassava mosaic disease
The gene pools for breeding cassava (Manihot esculenta Crantz) in Africa currently contain only a fraction of the existing genetic variation found in Latin America where the crop originates. Our research aimed to broaden the genetic base in Africa by introducing Latin American (LA) germplasm. The...

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 ...

Cassava is a major staple and food security
crop in Africa which can produce a crop under
uncertain rainfall and low fertility conditions. How-
ever, it suffers from several pests and diseases, with
Cassava Mosaic Disease (CMD) being the main biotic
constraint in production in s...

Cassava (Manihot esculenta) is a tropical crop that is grown in Africa, Latin America and Southeast Asia. Cassava was introduced from Latin America into West and East Africa at two independent events. In Uganda a serious threat to cassava's survival is the cassava mosaic disease (CMD). Uganda has...
