Resumo: The objective of this study was to evaluate the agronomic performance and genetic gain by the selection of half‑sib families of physic nut grown in three Brazilian regions. Based on previous phenotypic selection, three progeny tests were performed, in 2008, in the municipalities of Planaltina, DF, Nova Porteirinha, MG, and Pelotas, RS. A randomized complete block design was used, with three replicates, and five plants per plot. Randomly collected seeds from a population without selection were used as control. There was a significant interaction between the effects of genotypes and environments. Estimates of variance components and genetic parameters indicated that it is possible to obtain genetic gains from selection of the best families in the evaluated environments. In each environment, at least one family was selected with a higher performance than the control treatment. Mass selection in the three environments provided 72% of genetic gains. The agronomic performance had a high correlation coefficient between the environments of Planaltina and Nova Porteirinha, which did not occur in Pelotas. Genotype x environment interaction should be considered in the recommendations of physic nut genetic material for different environments.

A partir de seleção fenotípica prévia, foram instalados três testes de progênies, em 2008, nos municípios de Planaltina, DF, Nova Porteirinha, MG, e Pelotas, RS. Utilizou-se o delineamento de blocos ao acaso, com três repetições e cinco plantas por parcela. Como testemunha, foram utilizadas sementes, colhidas ao acaso, de uma população sem seleção. Houve interação significativa entre os efeitos de genótipos por ambientes. As estimativas dos componentes de variância e dos parâmetros genéticos indicaram que é possível obter ganhos com a seleção das melhores famílias, nos ambientes avaliados. Em cada ambiente, ao menos uma família foi selecionada com desempenho superior ao tratamento‑controle. O ganho genético médio, obtido pela seleção massal nos três ambientes, foi de 72%. Observou-se alto coeficiente de correlação entre os ambientes de Planaltina e Nova Porteirinha, quanto ao desempenho agronômico, o que não se repetiu no Município de Pelotas. A interação genótipo x ambiente deve ser considerada na recomendação de materiais genéticos de pinhão‑manso para ambientes distintos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFinepCNPqLaviola, Bruno GalvêasSilva, Sergio Delmar dos Anjos eJuhász, Ana Cristina PintoRocha, Rodrigo BarrosOliveira, Reriton Joabél Pires deAlbrecht, Julio CesarAlves, Alexandre AlonsoRosado, Tatiana Barbosa2014-06-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/18760Pesquisa Agropecuaria Brasileira; v.49, n.5, maio 2014; 356-363Pesquisa Agropecuária Brasileira; v.49, n.5, maio 2014; 356-3631678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/18760/12641https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/18760/11145info:eu-repo/semantics/openAccess2014-07-01T19:03:19Zoai:ojs.seer.sct.embrapa.br:article/18760Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-01T19:03:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
