Resumo: Vascular wilting in tomato plants is an important disease caused by soil-inhabiting pathogens, especially Verticillium dahliae, which results in significant production losses. Control measures against this disease are difficult to implement due to intrinsic pathogen characteristics, such as high adaptability to the subterranean environment, in association with the host, and development of resistance structures that remain viable in the soil for long periods. The introgression of genes that express resistance is the main control measure and requires a continuous characterization program of resistant accessions. This study aimed at identifying tomato (Solanum lycopersicum) accessions resistant to V. dahlia, by using the phenotypic and genotypic methods. The reaction of 33 tomato accessions to different V. dahliae isolates was reinforced by molecular analysis, through markers linked to Ve resistance genes. The combination of bioassays and specific molecular markers showed a high correlation (94.3 %), with the selection of 25 accessions resistant to V. dahliae.

A dificuldade de controle dessa doença advém de características intrínsecas do patógeno, como alta adaptabilidade ao ambiente subterrâneo, em associação com o hospedeiro, e produção de estruturas de resistência que permanecem viáveis no solo por longo tempo. A introgressão de genes que expressam resistência destaca-se como principal medida de controle, o que requer um programa contínuo de caracterização de acessos resistentes. Objetivou-se avaliar e identificar acessos de tomateiro (Solanum lycopersicum) resistentes a V. dahliae, pelos métodos fenotípico e genotípico. A reação de 33 acessos de tomateiro a diferentes isolados de V. dahliae foi corroborada com análises empregando-se marcadores moleculares ligados aos genes de resistência Ve. A combinação de bioensaios e marcadores moleculares específicos mostrou elevada correlação (94,3 %), com a seleção de 25 acessos resistentes a V. dahliae.Escola de Agronomia - Universidade Federal de Goiás2017-01-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/43106Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 4, Oct./Dec. 2016; 429-433Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 4, out./dez. 2016; 429-433Pesquisa Agropecuária Tropical; v. 46, n. 4, out./dez. 2016; 429-4331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/43106/22293Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessCarrer Filho, RenatoOliveira, Renata MariaDias, Vanessa DuarteRocha, Geisiane AlvesDianese, Érico de CamposCunha, Marcos Gomes da2020-07-13T18:20:04Zoai:ojs.revistas.ufg.br:article/43106Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:15.338467Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
