Resumo: Eight segregating populations of wheat (Triticum aestivum L.) were studied as to their days of flowering and plant height traits in two generations (F3 and F4) in order to establish their influence on grain yield. The populations were conducted under two selection procedures: modified SSD and pedigree method. Genetic variability (high for days to flowering and low for plant height) was present in the populations studied. Artificial selection and measurement of characters demonstrated a significant advance due to the modified pedigree method procedure applied in F2 and tested in F3 and F4 generations for the adaptative traits, showing direct contribution in reduction of number of days to flowering and plant height; thereby showing significant moving of the population mean of those traits. However, there was no evidence of the progress in the character indirectly influenced by two selection procedures. Similarly the selection for these traits had small influence on moving the population mean for grain yield.

As populações foram conduzidas sob dois procedimentos de seleção: SSD e genealógico modificados. Foi detectada variabilidade genética no ciclo e estatura de planta nas populações utilizadas. A seleção artificial e a avaliação dos caracteres demonstraram um avanço significativo em virtude do procedimento de seleção genealógico modificado aplicado aos caracteres adaptativos na geração F2 e testado nas gerações F3 e F4, mostrando contribuição direta na redução no ciclo e na estatura de planta, além de significante progresso genético nas populações selecionadas. Não há evidências de progresso no rendimento de grãos, e a seleção referente ao período de florescimento e estatura de planta tem pequena influência na alteração da média da população no que se refere à produtividade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarvajal, Casiano QuintanaCarvalho, Fernando Irajá Félix deBarbieri, Rosa LíaKohli, Man MohanFederizzi, Luiz CarlosPacheco, Marcelo Teixeira1997-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4763Pesquisa Agropecuaria Brasileira; v.32, n.11, nov. 1997; 1167-1176Pesquisa Agropecuária Brasileira; v.32, n.11, nov. 1997; 1167-11761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4763/7271info:eu-repo/semantics/openAccess2015-04-14T17:40:29Zoai:ojs.seer.sct.embrapa.br:article/4763Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-04-14T17:40:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
