Resumo: The wild species Avena sterilis L. has been widely used for crossing with cultivated oat. The high affinity between them enables an increase in genetic variability and transference of important agronomic genes. However, undesirable characters such as great plant height and length of the panicle can be transferred to progenies. These characters were analysed to evaluate the genetic variability and inheritance in crossing between Avena sativa L. and Avena sterilis L. Estimates of phenotypical and genetical variances were high while the environmental variance was low, providing a high broad sense heritability. The additive gene effect was the most important for explaining the genetic variation for both characters.

Entretanto, caracteres indesejáveis, como a alta estatura e um maior comprimento de panícula, podem ser transferidos à progênie. Nesse sentido, com o objetivo de avaliar a variabilidade genética, bem como a herança em cruzamentos entre Avena sativa L. e Avena sterilis L., foram mensurados os caracteres estatura de planta e comprimento da panícula principal. As variâncias fenotípicas e genéticas foram altas e as variâncias de ambiente foram baixas, proporcionando uma alta herdabilidade no sentido amplo. O efeito gênico de aditividade foi o mais importante para explicar a variação genética em ambos os caracteres.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMariot, Márcio PaimSereno, Maria Jane Cruz de MeloFederizzi, Luiz CarlosCarvalho, Fernando Irajá Félix de1999-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5136Pesquisa Agropecuaria Brasileira; v.34, n.1, jan. 1999; 77-82Pesquisa Agropecuária Brasileira; v.34, n.1, jan. 1999; 77-821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5136/2328info:eu-repo/semantics/openAccess2010-07-15T14:12:59Zoai:ojs.seer.sct.embrapa.br:article/5136Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-15T14:12:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
