Resumo: | Cowpea is a staple food in the Northeast of Brazil, thus, genetic improvement of this species is important. Samples of cowpea landraces were collected in the State of Rio Grande do Norte, Brazil, and the most promising ones were evaluated in the present study. The objective was to identify the most productive varieties and the characteristics that have greater direct effect on grain yield, for breeding purposes. Twelve landraces were evaluated using a randomized block design with five replications, in two experiments—one in the dry season, and other in the rainy season. However, water irrigation was used in both experiments, due to the almost total absence of rainfall in the rainy season. The Baraúna, and Carnaubais cowpea varieties were the most productive in both experiments. Campo Grande was the best variety found in the experiment carried out in the dry season. José da Penha, Lagoa de Pedra, Umarizal, and Upanema were the best varieties in the experiment carried out in the rainy season. The number of pods per plant was the characteristic that had greater direct effect on grain yield. |

Foram coletadas variedades tradicionais dessa cultura no Estado do Rio Grande do Norte e as mais promissoras foram avaliadas no presente trabalho. Objetivou-se identificar as mais produtivas e distinguir, entre as características avaliadas, a que possui o maior efeito direto sobre o rendimento de grãos, para fins de melhoramento. Doze variedades foram avaliadas em blocos ao acaso com cinco repetições em dois experimentos. Um dos experimentos foi irrigado. O outro experimento foi realizado na época das chuvas, mas requereu irrigação devido à ausência quase que total de chuvas. As variedades Baraúna e Carnaubais foram as mais produtivas nos dois experimentos. No experimento realizado com irrigação foi destaque a variedade Campo Grande. Sob condições de sequeiro (com chuvas) destacaram-se também as variedades José da Penha, Lagoa de Pedra, Umarizal e Upanema. O número de vagens por planta foi o principal caráter a influenciar o rendimento de grãos.Universidade Federal Rural do Semi-Árido2019-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/730410.1590/1983-21252019v32n202rcREVISTA CAATINGA; Vol. 32 No. 2 (2019); 302-311Revista Caatinga; v. 32 n. 2 (2019); 302-3111983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7304/9945Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessFreitas, Thaisy Gardênia Gurgel deSilva, Paulo Sérgio Lima eDoVale, Júlio CésarSilva, Ítalo NunesSilva, Edicleide Macedo da2023-07-20T17:07:36Zoai:ojs.periodicos.ufersa.edu.br:article/7304Revistahttps://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:2024-04-29T09:46:34.562927Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
