Cassava brown streak disease (CBSD) is the most important virus disease of cassava and a major food security threat in Africa. Yearly economic losses of up to $100 million USD have been attributed to CBSD. The lack of information on plant-virus interactions has restricted progress in breeding for...

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...

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 is an important staple food in subtropical regions; however, its production is adversely affected by cassava brown streak disease and poor soil fertility. Five improved and two local cassava varieties were evaluated for three seasons across two sites in Kizimbani, Zanzibar. Highly signifi...

Cassava (Manihot esculenta Crantz) and the viruses that infect it, notably cassava mosaic virus and cassava brown streak viruses, have a unique history of co-evolution and co-existence. While cassava originated in South America, both viruses and the diseases they cause have largely been limited t...

Cassava brown streak disease (CBSD) remains a major threat to the livelihoods of millions of smallholders in sub-Saharan Africa. This viral disease was initially confined to the coastal lowland areas of eastern and southern Africa. More recently there has been a major new outbreak in the Great La...

Cassava is a key food security crop in sub-Saharan Africa, and is increasingly offering opportunities for income generation from the sale of fresh roots, cuttings and diverse processed products. The total fresh root production is increasingly constrained, by the two principal biotic constraints; ...
