Genotype by environment interactions in identifying cassava (Manihot esculenta Crantz) resistant to cassava brown streak disease
Emily A. Masinde,Emily A. Masinde,Geoffrey Mkamillo,Joshua O. Ogendo,Rory Hillocks,Richard Mulwa,Bernadetta Kimata,Midatharahally N. Maruthi +7 more
TL;DR: Correlation analysis showed that the presence of CBSD symptoms reduces the amount of usable roots, total root weight, and root dry matter content, and they can be used by farmers to reduce CBSD losses.

Disparity between Leaf and Root Symptoms and Crop Losses Associated with Cassava Brown Streak Disease in Four Countries in Eastern Africa
Rory Hillocks,Midatharahally N. Maruthi,Heneriko Kulembeka,Simon C. Jeremiah,Francis Alacho,Emily A. Masinde,Joshua O. Ogendo,P.F. Arama,Richard Mulwa,Geoffrey Mkamilo,Bernadetta Kimata,Davis Mwakanyamale,Albert Mhone,Ibrahim Benesi +13 more
TL;DR: CBSD leaf symptoms were recorded at high incidences in all fields visited throughout East Africa, butRoot necrosis incidence was lower than would be expected from the high incidence of leaf symptoms, and it appears that varieties that are prone to root necrosis are being abandoned in favour of those with a lower propensity to developroot necrosis after infection by the virus.

TL;DR: In this paper, the authors investigated the effect of interaction between time of harvesting and levels of disease resistance to identify ideal harvesting times for reducing yield losses in Eastern and Southern Africa cassava production.

TL;DR: A multiplex TaqMan‐based real‐time PCR assay for the simultaneous detection and quantification of both RNA and DNA viruses affecting cassava in eastern Africa is developed.
Developing dual resistant cassava to the two major viral diseases
Emily A. Masinde,Bernadetta Kimata,Joshua O. Ogendo,Richard Mulwa,Geoffrey Mkamilo,Midatharahally N. Maruthi +5 more
TL;DR: In this paper, the authors carried out cross-crossing between the Tanzanian local cassava variety Namikonga (CBSD resistant/CMD susceptible) with an introduced cassava germplasm AR37-80 from South America to develop dually resistant F1 progenies and they were evaluated for 2 seasons at Naliendele in Southern Tanzania which is a CMD and CBSD hotspot area.
