Resumo: The objective of this work was to evaluate the agronomic performance of kale genotypes and to estimate the genetic parameters and the correlation between traits of interest for breeding. The experiment was carried out in a randomized block design, with 30 kale genotypes, with three commercial cultivars, from three different companies. It was used four replicates, with five individuals per plot. Variability was significant among genotypes, with predominance of genetic effects over environmental ones, indicating the possibility of obtaining expressive genetic gains in breeding. The most important traits for breeding purposes were: leaf length and width, stem diameter, leaf area, plant height, number of shoots, and leaf dry weight. Commercial genotypes showed smaller leaf area, dry leaf mass, plant height, leaf length and width, petiole length, and number of sprouts and commercial leaves.

O experimento foi realizado em delineamento de blocos ao acaso, com 30 genótipos de couve, entre os quais, três cultivares comerciais, de diferentes empresas. Foram utilizadas quatro repetições, com cinco indivíduos por parcela. Verificou-se variabilidade genética entre os genótipos, com predominância dos efeitos genéticos sobre os ambientais, o que indica a possibilidade de se obterem ganhos genéticos representativos com o melhoramento. As características importantes para o melhoramento da espécie foram: comprimento e largura de folha, diâmetro de pecíolo, área foliar, altura de planta, número de brotações e massa de folhas secas. Os genótipos comerciais apresentaram menor área foliar, massa de matéria seca de folhas, altura de planta, comprimento e largura de folha, comprimento de pecíolo, e número de brotações e de folhas comerciais.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPEMIG, CNPq e CAPESFAPEMIGCNPqCAPESAzevedo, Alcinei MisticoAndrade Júnior, Valter Carvalho dePedrosa, Carlos EnrrikFernandes, José Sebastião CunhaValadares, Nermy RibeiroFerreira, Marcos Aurélio MirandaMartins, Rafael Augusto do Valle2013-01-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/12652Pesquisa Agropecuaria Brasileira; v.47, n.12, dez. 2012; 1751-1758Pesquisa Agropecuária Brasileira; v.47, n.12, dez. 2012; 1751-17581678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/12652/8313https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/12652/8333info:eu-repo/semantics/openAccess2013-01-22T16:52:56Zoai:ojs.seer.sct.embrapa.br:article/12652Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-01-22T16:52:56Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
