Resumo: Cowpea [Vigna unguiculata (L.) Walp.] is an important socioeconomic crop in Brazil, mainly in the Northeast and more recently in the Midwest of Brazil. Charcoal rot caused by Macrophomina phaseolina (Tassi) Goid, is an important disease in semiarid regions, where edaphoclimatic conditions are favorable to the development of disease. The aim of this study was to evaluate the response of 100 cowpea lines to two isolates of M. phaseolina. The experiments were conducted in a completely randomized design, with five replications (two plants per pot). The main variables evaluated were lesion length and relative growth compared to control (RGCC). Among the evaluated accessions, 15% of the lines were resistant to isolate 59 and 11% of the lines were resistant to isolate CMM 2106 of M. phaseolina. Therefore, these accessions can be used as a source of resistance to M. phaseolina by farmers directly as new cultivars or in future hybridizations of cowpea genetic breeding programs.

Walp.] é uma importante cultura socioeconomicamente, principalmente na região nordeste e, mais recentemente no centro-oeste do Brasil. Podridão cinzenta do caule causada pelo fungo Macrophomina phaseolina (Tassi) Goid, é importante em regiões semiáridas, onde as condições edafoclimáticas são favoráveis para o desenvolvimento da doença.  O objetivo deste estudo foi avaliar a reação de 100 linhagens de feijão-caupi à dois isolados de M. phaseolina. Os experimentos foram conduzidos em delineamento inteiramente casualizado com cinco repetições (duas plantas por parcela). As principais variáveis analisadas foram comprimento da lesão e crescimento relativo a testemunha.  Entre os acessos avaliados, 15% das linhagens foram resistentes ao isolado 59 e 11% foram resistentes ao isolado CMM 2106 de M. phaseolina. Portanto, os acessos podem ser utilizados como fontes de resistência a M. phaseolina pelos agricultores diretamente como cultivares ou em futuros cruzamentos de programas de melhoramento genético do feijão-caupi.Universidade Federal Rural do Semi-Árido2022-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1031210.1590/1983-21252022v35n305rcREVISTA CAATINGA; Vol. 35 No. 3 (2022); 548-556Revista Caatinga; v. 35 n. 3 (2022); 548-5561983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10312/10984Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessAraújo, Kecia Mayara Galvão deNascimento, Luan Felipe Santos do Siqueira e Silva, Pedro Ivo Silvestre Borel, Jerônimo ConstantinoSilva, Kaesel Jackson Damasceno eIshikawa, Francine Hiromi2023-07-03T13:58:16Zoai:ojs.periodicos.ufersa.edu.br:article/10312Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:56.105757Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
