Training Population Optimization for Prediction of Cassava Brown Streak Disease Resistance in West African Clones

G3: Genes, Genomes, Genetics, 2018
Cassava production in the central, southern and eastern parts of Africa is under threat by cassava brown streak virus (CBSV). Yield losses of up to 100% occur in cases of severe infections of edible roots.

Resistance Against Cassava Brown Streak Viruses From Africa in Cassava Germplasm From South America

Frontiers in Plant Science, 2019
Cassava brown streak disease (CBSD) is a severe virus disease of cassava and prevalent in the eastern regions of Africa. The disease is characterized by distinct vein chlorosis and streak symptoms on leaves and stems and necrosis of storage roots.

Risk factors associated with cassava brown streak disease dissemination through seed pathways in Eastern D.R. Congo

Frontiers in Plant Science, 2022
Vegetatively propagated crops are particularly prone to disease dissemination through their seed systems. Strict phytosanitary measures are important to limit the impact of diseases as illustrated by the potato seed system in Europe. Cassava brown streak

Occurrence and estimated losses caused by cassava brown streak disease in Migori county, Kenya [PDF]

, 2016
Cassava is the second most important staple crop after maize in Migori County. A farm survey was conducted in Kuria East and Suna West sub-counties to determine the incidence, severity and estimated losses of cassava brown streak disease (CBSD) on ...

Unlocking Cassava Brown Streak Disease Resistance in Cassava: Insights from Genetic Variability and Combining Ability

Agronomy
Cassava brown streak disease (CBSD) threatens cassava production in sub-Saharan Africa despite the availability of resistant varieties. Extreme environmental factors weaken plant defenses, reducing CBSD resistance. This study examined CBSD inheritance in

Impact of host plant species and whitefly species on feeding behavior of Bemisia tabaci [PDF]

, 2019
Whiteflies of the Bemisia tabaci species complex are economically important pests of cassava. In Africa, they cause greatest damage through vectoring viruses responsible for cassava mosaic disease and cassava brown streak disease. Several cryptic species

Production of virus-free cassava through hot water therapy and two rounds of meristem tip culture

Cogent Food & Agriculture, 2020
Cassava genetic resources are highly threatened by devastating viral diseases. It is therefore important to conserve the specifically farmer-preferred landraces/cultivars that are highly susceptible. The study assessed the efficiency of hot water therapy

QTL associated with resistance to cassava brown streak and cassava mosaic diseases in a bi-parental cross of two Tanzanian farmer varieties, Namikonga and Albert [PDF]

, 2017
Article purchasedCassava 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 ...
