In Sub-Saharan Africa cassava (Manihot esculenta Crantz) is one of the most important food crops where more than 40% of the population relies on it as their staple carbohydrate source. Biotic constraints such as viral diseases, mainly Cassava Mosaic Disease (CMD) and Cassava Brown Streak Disease (CBSD), and arthropod pests, particularly Cassava Green Mite (CGM), are major constraints to the realization of cassava's full production potential in Africa. To address these problems, we aimed to map the quantitative trait loci (QTL) associated with resistance to CBSD foliar and root necrosis symptoms, foliar CMD and CGM symptoms in a full-sib mapping population derived from the genotypes AR40-6 and Albert.

- Cassava brown steak disease (CBSD) is a major threat to cassava production in East and Central Africa, caused by two viruses, CBSV and UCBSV.
- A multi-country study aimed to identify and promote cassava cultivars resistant to CBSD across various conditions in Tanzania, where 17 different cultivars were tested.
- Results showed significant differences in CBSD infection rates based on location, with certain resistant cultivars demonstrating less than 20% incidence, while the CBSD was found to be more virulent than UCBSV.
