Resumo: The downy mildew, caused by the fungus Pseudoperonospora cubensis is a major foliar disease that attacks the melon crop in the rainy season in northeastern Brazil. The objective of this study was to identify and characterize morphologically resistant melon accessions to P. cubensis. Thirty-six accessions and four commercial cultivars were evaluated in a randomized block design with three replications. The plot was composed of seven plants. The evaluation was conducted in the under field conditions with a diagrammatic scale and calculating the disease percentage index (DPI). Resistance sources and references genotypes were characterized morphologically. The accessions C-RN-2, C-SE-2, C-CE-2, C-PE-2, C-PI-1, and C-BA-2 show resistance to P. cubensis and are promising for use in programs breeding for resistance to downy mildew although its fruits have reduced commercial quality.

O objetivo do presente trabalho foi identificar e caracterizar morfologicamente fontes de resistência de meloeiro a P. cubensis. Trinta e seis acessos e quatro cultivares comerciais foram avaliados em delineamento em blocos casualizados com três repetições. A unidade experimental foi composta por sete plantas. E a avaliação realizada em condições de campo com uma escala diagramática, a qual fora calculado o índice de porcentagem da doença (IPD). As fontes de resistência e genótipos referências foram caracterizadas morfologicamente. Os acessos C-RN-2, C-SE-2, C-CE-2, C-PE-2, C-PI-1 e C-BA-2 apresentam resistência a P. cubensis e são promissores para uso em programas de melhoramento visando resistência ao míldio do meloeiro, embora os seus frutos tenham reduzida qualidade comercial.Universidade Federal Rural do Semi-Árido2015-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/430310.1590/1983-21252015v28n312rcREVISTA CAATINGA; Vol. 28 No. 3 (2015); 100-107Revista Caatinga; v. 28 n. 3 (2015); 100-1071983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/4303/pdf_281Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessAlbuquerque, Leidiane BezerraAntonio, Rafaela PriscilaNunes, Glauber Henrique de SousaMedeiros, Ravier Valcácer deSilva Filho, Antonio José Rodrigues da2023-07-27T12:57:35Zoai:ojs.periodicos.ufersa.edu.br:article/4303Revistahttps://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:2024-04-29T09:46:14.623374Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
