Resumo: | The objective of the present work was to estimate the general combining ability (GCA) and specific combining ability (SCA) in the grain yield traits components through diallel cross of six bean (Phaseolus vulgaris L.) genotype using the method 2, model B, suggested by Griffing. The experiment was carried out in a complete randomized block design, with four replications, in 1998. The studied traits were: average weight grain; number of grain/pod; number of pod/plant and grain yield. The results of GCA evidenced more importance than SCA for all traits. According to the estimate of GCA, the parent Rudá showed the best values to the traits evaluated. In this way, the greater effect of SCA for the general traits were to get in wrapping up cross with parent Rudá x CI 967/2V, Rudá x FT Nobre and Pérola x CI 9661, determining the importance of these parents for the species improvement programs. |

O experimento, em blocos completos casualizados, com quatro repetições, foi conduzido na safra de 1998, onde foram avaliados os seguintes caracteres: peso médio do grão; número de grãos/legume; número de legumes/planta, e rendimento. Os resultados da análise de variância evidenciaram maior importância da CGC em relação à CEC para todos os caracteres. Conforme a estimativa da CGC, o genitor Rudá foi o que apresentou, de modo geral, os melhores valores para os caracteres avaliados. Do mesmo modo, o maior efeito da CEC para os caracteres em geral foi obtido nos cruzamentos envolvendo os genitores Rudá x CI 967/2V, Rudá x FT Nobre e Pérola x CI 9661, determinando a importância desses genitores para os programas de melhoramento do feijão.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraKurek, Adreomar JoséCarvalho, Fernando Irajá Félix deAssmann, Isidoro CarlosCruz, Pedro Jacinto2001-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6179Pesquisa Agropecuaria Brasileira; v.36, n.4, abr. 2001; 645-651Pesquisa Agropecuária Brasileira; v.36, n.4, abr. 2001; 645-6511678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6179/3244info:eu-repo/semantics/openAccess2010-08-09T12:47:47Zoai:ojs.seer.sct.embrapa.br:article/6179Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T12:47:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
