Resumo: This study was carried out at the Centro Nacional de Pesquisa de Suínos e Aves (National Swine and Poultry Research Center/EMBRAPA) with the objective of testing four commercial strains of meat-type chickens using diallel crosses. There were four male lines and four female lines, identified by L (L1, L2, L3 and L4) and P (P1, P2, P3 and P4), respectively. The analysis of diallel crosses among strains, within male and female lines was based on body weight at 42 days. There were significant differences among crosses on body weight and reciprocal effects, general and specific combining ability. The lines that showed best results for body weight at 42 days were P2 and L2.

Estas foram denominadas L1, L2, L3, L4, P1, P2, P3 e P4; as letras L e P identificam, respectivamente, as linhas produtoras de matrizes macho e fêmea, e os números de l a 4, as diferentes origens. Efetuou-se a análise do cruzamento dialélico entre linhagens, separadamente para as linhas de macho e fêmea, quanto ao peso corporal aos 42 dias. Foram observadas diferenças significa­tivas entre os cruzamentos, para a característica avaliada. Os efeitos da capacidade geral e es­pecífica de combinação e efeitos recíprocos foram significativos. As linhagens P2 (linha fê­mea) e L2 (linha macho) apresentaram efeitos médios mais favoráveis quanto ao peso corpo­ral aos 42 dias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSchmidt, Gilberto S.Packer, Irineu UmbertoDuarte, Francisco Alberto de MouraCosta, Cláudio Napolis1991-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3404Pesquisa Agropecuaria Brasileira; v.26, n.6, jun. 1991; 779-784Pesquisa Agropecuária Brasileira; v.26, n.6, jun. 1991; 779-7841678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3404/737info:eu-repo/semantics/openAccess2010-03-31T13:26:54Zoai:ojs.seer.sct.embrapa.br:article/3404Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-03-31T13:26:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
