Resumo: | The objective of this work was to evaluate the efficiency of the independent component regression (ICR) method for the estimation of genomic values and of SNP marker effects for carcass traits in a F2 pig population (Piau x commercial line). The methods were evaluated by the agreement between the genetic predicted values and the corrected phenotypes observed by cross‑validation, and they were also compared with other methods generally used for the same purposes, such as RR‑BLUP, PCR, and PLS. The ICR and PCR methods show similar results, but ICR has the highest accuracy prediction values. |

Os métodos foram avaliados por meio da concordância entre os valores genéticos preditos e os fenótipos corrigidos, observados por validação cruzada, e também foram comparados com outros métodos geralmente utilizados para os mesmos propósitos, tais como RR‑BLUP, PCR e PLS. Os métodos ICR e PCR apresentam resultados similares, mas o método ICR apresenta maiores valores de acurácia.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAzevedo, Camila FerreiraResende, Marcos Deon Vilela deSilva, Fabyano Fonseca eLopes, Paulo SávioGuimarães, Simone Eliza Facioni2013-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14002Pesquisa Agropecuaria Brasileira; v.48, n.6, jun. 2013; 619-626Pesquisa Agropecuária Brasileira; v.48, n.6, jun. 2013; 619-6261678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14002/12153https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/14002/9408info:eu-repo/semantics/openAccess2013-09-05T19:39:27Zoai:ojs.seer.sct.embrapa.br:article/14002Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-09-05T19:39:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
