Abstract
A murcha-de-fusarium, causada por Fusarium oxysporum f. sp. phaseoli, b doença séria em muitas areas produtoras de feijão do Brasil, especialmente nas irrigadas. A patogenicidade do isolado FOP 46 em 12 cultivares/linhagens de feijão foi avaliada em casa de vegetação. Turmalina e Rosinha mostraram-se suscetiveis, enquanto Paola, Vi. 13-8-3, EEP 558, CF 880065, Vi. 12-1-2, Vi. 343-1, Vi. 10-2-1, Vi. I6-3-3, Carnaval e Novirex foram resistentes.
Fusarium wilt, caused by Fusarium oxysporum f. sp. phaseoli, is a serious disease of common beans in many production areas in Brazil, mainly in the irrigated ones. The pathogenicity of the isolate FOP 46, obtained at CNPAF/Embrapa, to 12 cultivars and lines, which have been tested by Epamig and Federal University of Viçosa, was evaluated under greenhouse conditions. Cultivars Pérola and Rosinha were used as resistant and susceptible controls, respectively. Turmalina was susceptible to the pathogen while the lines Vi. 13-8-3, EEP 558, CF 880065, Vi. 12-1-2, Vi. 3-13-1, Vi. 10-2-1, Vi. 16-3-3 and the cultivarsCarnaval and Novirex were resistants.
