Resumo: Eight corn varieties, with great genetic diversity among them, were studied in a diallel cross system in order to evaluate their breeding potential. The means of the varieties, their hybrids and advanced generations were analyzed using the Gardner & Eberhart (1966) model. With the genetic constants estimated it was possible to estimate the mean grain yield for several types of populations (double hybrids, triple hybrids, synthetic varieties, etc). The best varieties were: Tuxpeño La Posta, Eto Blanco, Centralmex and Pérola Piracicaba.

Foi utilizado o modelo proposto por Gardner & Eberhart (1966) para estimar as constantes genéticas a partir das quais foram estimadas as médias de rendimentos (peso de grãos) das populações de interesse. As variedades que mais se sobressaíram foram, em ordem decrescente de importância: Tuxpeño La Posta, Eto Blanco, Centralmex e Pérola Piracicaba.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPinto, Luiz Roberto MartinsSilva, José CarlosSediyama, Carlos SigueyukiSilva, Martinho de Almeida e2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14785Pesquisa Agropecuaria Brasileira; v.22, n.09/10, set./out. 1987; 975-986Pesquisa Agropecuária Brasileira; v.22, n.09/10, set./out. 1987; 975-9861678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14785/8799info:eu-repo/semantics/openAccess2014-10-10T18:08:14Zoai:ojs.seer.sct.embrapa.br:article/14785Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-10T18:08:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
