Abstract

Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) have been two major threats to cassava production in eastern and southern Africa. This study was designed to identify CMD- and CBSD-resistant cassava landraces and farmer-preferred varieties in Malawi for effective disease control. Thirty
cassava landraces were collected from 17 districts across Malawi and evaluated for disease resistance a field experiment at the Chitala Research Station in a randomized complete block design (RCBD). Cultivars Mbundumali and Pwani were used as susceptible and resistant controls, respectively. Data collected on
foliar and root disease symptoms indicated that CMD was more prominent than CBSD during the study. Cultivars Pwani, Mkumba, R23-Sangwala, Sagonja, R31-Kamphunobi, R33-Chimphuno, R76-Kamphuno, MZ126, and R63-2020 showed relative dual resistance to both CMD and CBSD with the highest incidence of 25 and 18%, respectively. Some cultivars showed resistance to one disease and not the other. The lowest cumula
