Resumo: The genetic elimination of lipoxygenase (Lox 1, Lox 2 and Lox 3) enzymes from soybean seeds is a way to overcome the problems associated with the undesirable beany flavor of soybean seeds. Aiming at elucidating the influence of this genetic elimination on the agronomic characteristics of the soybean plants and grain yield components, the commercial variety of soybean FT-Cristalina RCH and its backcross derived lines, lacking the three lipoxygenases in the seeds (triple-null) and with these enzymes (triple-positive) were evaluated at three sowing dates. The commercial variety was more homogeneous than the lines with or without lipoxygenases, indicating the presence of significant amount of genes of the non-recurrent progenitors in the lines, mainly in the triple-null. The different sowing dates evidenced more differences among genetic materials (commercial variety, triple-null and triple-positive lines), in plant characteristics and grain yield components. The genetic elimination of lipoxygenases of the seeds did not negatively affect the agronomic characteristics of FT-Cristalina RCH soybean variety.

Visando elucidar a influência dessa eliminação genética nas características agronômicas da planta de soja e nos componentes de produção, a variedade comercial de soja FT-Cristalina RCH e suas linhagens, obtidas por retrocruzamentos, sem as três lipoxigenases nas sementes (linhagens triplo-nulas) e com as três lipoxigenases (triplo-positivas), foram avaliadas em três épocas de semeadura. A variedade comercial foi mais homogênea que as linhagens com ou sem lipoxigenases, indicando presença de quantidade significativa de genes dos progenitores não-recorrentes nas linhagens, principalmente nas sem lipoxigenases. A semeadura em diferentes épocas evidenciou variação entre os materiais genéticos (variedade comercial, linhagens com ou sem lipoxigenase nas sementes), tanto nas características da planta quanto nos componentes de produção de grãos. A eliminação genética das lipoxigenases das sementes não afetou negativamente as características agronômicas da variedade FT-Cristalina RCH.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMartins, Carlos Alberto OsórioSediyama, Carlos SigueyukiMoreira, Maurílio AlvesReis, Múcio SilvaRocha, Valterley SoaresOliveira, Maria Goreti de Almeida2002-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6482Pesquisa Agropecuaria Brasileira; v.37, n.10, out. 2002; 1389-1398Pesquisa Agropecuária Brasileira; v.37, n.10, out. 2002; 1389-13981678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6482/3539info:eu-repo/semantics/openAccess2014-07-22T17:48:47Zoai:ojs.seer.sct.embrapa.br:article/6482Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-22T17:48:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
