Resumo: Seven bean (Phaseolus vulgaris L.) cultivars were crossed following a half-diallel model and data were obtained from the parents and F2 generation, in order to determine the genetic control of grain yield and its primary components. A randomized block design with three replications was used in two locations of Minas Gerais State, Brazil, in 1981. The method proposed by Jinks and Hayman for analyzing diallel crosses was used, and the data met the assumptions of the model, except in three cases, where an adjustment was necessary to fit the model. The additive gene action was predominant in relation to dominance for all traits. Consequently, one should consider the mean behavior of the cultivars and of the segregant populations to carry out a breeding program. There was a significant interaction between gene action and locations.

Utilizou-se o delineamento de blocos casualizados com três repetições e dois locais do Estado de Minas Gerais, em 1981. Foi usado o método dialélico desenvolvido originalmente por Jinks e Hayman, onde se verificou que a maioria dos dados adequou-se ao modelo genético empregado, exceto em três casos, em que foi necessário um ajustamento para adequação ao modelo. A ação gênica aditiva foi predominante em relação à dominância em todos os caracteres. Em consequência, deve-se considerar o comportamento médio das cultivares e das populações segregantes, para a seleção dos materiais a serem utilizados nos programas de melhoramento. Observaram-se acentuadas interações das ações gênicas com locais.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, João Bosco dosVencovsky, RolandRamalho, Magno Antonio Patto2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16289Pesquisa Agropecuaria Brasileira; v.20, n.10, out. 1985; 1203-1211Pesquisa Agropecuária Brasileira; v.20, n.10, out. 1985; 1203-12111678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16289/10486info:eu-repo/semantics/openAccess2014-04-16T19:33:06Zoai:ojs.seer.sct.embrapa.br:article/16289Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:33:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
