Resumo: | Fusarium wilt, caused by soil-borne Fusarium oxysporum f. sp. tracheiphilum (Fot), can reduce cowpea bean yield. Considering that genetic control through resistant genotypes is pivotal for Fusarium wilt control, the aim of the present study was to identify cowpea genotypes that are resistant to Fot from the Germplasm Bank of the Pernambuco Agronomic Institute, Embrapa Middle North, and other producing areas in the North and Northeast regions of Brazil. The cultivar BR-17 Gurguéia was used as a susceptible control and MNCO1-649F-2-1 was used as a resistant control. Two experiments were carried out in a completely randomized design in the greenhouse of the Department of Agronomy of the University Federal Rural of Pernambuco. Plants with the first pair of expanded leaves were inoculated with a conidial suspension (106 conidia/mL) using the conidia root-immersion methodology. Fusarium wilt severity in plants was assessed 21 d after inoculation, with the aid of a descriptive scale. In the first experiment, we evaluated the resistance of 38 cowpea genotypes, of which 19 (5 moderately resistant and 14 resistant) were selected for the second experiment. In the first experiment, four genotypes (Canapu PE, Miranda IPA 207, Esperança, and BRS Pujante) did not show any symptoms of Fusarium wilt. In the second, 15 genotypes showed high resistance to Fot, including Canapu PE and Miranda IPA 207, which again had no symptoms of Fusarium wilt. In conclusion, this study identified that the genotypes, Canapu PE, Miranda IPA 207, Esperança, and BRS Pujante have greater resistance to Fusarium wilt. |

Este estudo teve como objetivo identificar genótipos com resistência à Fot oriundos do banco germoplasma do Instituto agronômico de Pernambuco, Embrapa Meio Norte e outras regiões produtoras da região Nordeste e Norte do Brasil. A cultivar BR-17 Gurguéia foi utilizada como controle suscetivel e a MNCO1-649F-2-1 como controle resistente. Dois experimentos foram conduzidos em um delineamento inteiramente casualizado em casa de vegetação pertencente ao Departamento de Agronomia da Universidade Federal Rural de Pernambuco. Plantas apresentando o primeiro par de folhas desenvolvidas foram inoculadas com uma suspensão de conídios (106 conídios/mL) utilizando a metodologia de imersão de raízes. A severidade da murcha de Fusarium foi determinada aos 21 dias após a inoculação através de uma escala descritiva. No primeiro experimento foi avaliado a resistência de 38 genótipos de feijão-caupi, sendo que 19 genótipos (5 moderadamente resistentes e 14 resistentes) foram selecionados para o segundo experimento. No primeiro experimento 4 genótipos (Canapu PE, Miranda IPA 207, Esperança e BRS Pujante) apresentaram ausência de sintomas. Para o segundo experimento, 15 genótipos apresentaram alto nível de resistência à infecção por Fot, com destaque para Canapu PE e Miranda IPA 207, aos quais novamente apresentaram ausência de sintomas de murcha. Em conclusão, este estudo identificou que os genótipos Canapu PE, Miranda IPA 207, Esperança e BRS Pujante apresentam maior resistência à murcha de Fusarium.
