Resumo: Six Brazilian bread wheat cultivars differing in tolerance to barley yellow dwarf virus (BYDV) were crossed according to a diallel design, to determine general and specific combining ability. A BYDV isolate transmitted by Rhopalosiphum padi (L.) was inoculated in plants when seedlings had two leaves. Ten days after anthesis each plant was examined receiving a score according to its symptom severity. Data were evaluated according to Griffing method, fixed model and method two. Heterosis was evidenced, related to the addictive effects of complementary genes. Cultivars BR 34 and BR 35 showed the best values of general combining ability (GCA). They are recommended as parents in wheat breeding programs to obtain tolerant genotypes to BYDV.

Um isolado do vírus transmitido por Rhopalosiphum padi (L.) foi inoculado nas cultivares e nos híbridos F1 no estádio de plântula com duas folhas. Foram atribuídas notas individuais a cada planta de acordo com a severidade de sintomas apresentados. Os dados obtidos foram analisados segundo os três métodos: o de Griffing, o modelo fixo, e méto-do 2. Ficou evidenciada a presença de heterose, provavelmente decorrente do efeito aditivo de genes complementares. As cultivares BR 34 e BR 35 se destacaram com melhores valores de capacidade geral de combinação (CGC), e é recomendado seu uso como genitores em programas de melhoramento de trigo que visem à obtenção de combinações genéticas com tolerância ao VNAC.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarbieri, Rosa LíaCarvalho, Fernando Irajá felix deBarbosa Neto, José FernandesCaetano, Vanderlei da RosaMarchioro, Volmir SérgioAzevedo, Roni deLonrecetti, Claudir2001-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6112Pesquisa Agropecuaria Brasileira; v.36, n.1, jan. 2001; 131-135Pesquisa Agropecuária Brasileira; v.36, n.1, jan. 2001; 131-1351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6112/3179info:eu-repo/semantics/openAccess2014-09-16T18:03:52Zoai:ojs.seer.sct.embrapa.br:article/6112Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-16T18:03:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
