Greenhouse screening of South African sweet potato cultivars and breeding lines for tolerance to Alternaria blight caused by Alternaria bataticola
African Plant Protection 16 (1), 10-13
Abstract: Alternaria blight (AB), caused by Alternaria bataticola, is a new disease report on sweet potato in South Africa. Although at present limited in distribution locally, the disease can be destructive under hot, humid conditions. Fourteen sweet potato cultivars and breeding lines were screened in the greenhouse for tolerance to AB. Monate, Khano, Impilo and Ndou showed the highest tolerance, whereas Ribbok, Serolane, Excel, Resisto, W-119 and Beauregard were the least tolerant. The level of AB infection was not related to the skin or flesh colour of storage roots.
