Resumo: The 15/65 race of Puccinia graminis tritici was predominant in the 255 stem rust samples collected in Brazilian wheat regions, in 1972 and 1973; that Taco accounted 74% and 50% respectively of the samples. The other races identified, in order of decreasing prevalence, were: in 1972: 11, 15/71, 17, 17/63, 17/61 and 17 T; in 1973,11/74,17/63,15/71,11 and 11 T. The 11/74 race was virulent only ongenos Sr 8 and Sr 11. It was first determined in 1973, second in order to prevalence, comprised about 35% of the samples. The combination of the genes Sr 7a and Sr 11 confers resistance to all occurrent races.

Henn, colhidas nas zonas tritícolas brasileiras, em 1972 e 1973, alcançando respectivamente 74% e 50% do total das amostras. Outras raças determinadas, em ordem decrescente de prevalência, foram: em 1972: 11, 15/71, 17, 17/63, 17/61 e 17 T: em 1973: 11/74, 17/63, 15/71, 11 e 11 T. A raça 11/74 é uma raça nova, determinada pela primeira vez em 1973 e caracteriza-se por somente os genes Sr 8 Sr 11 serem resistentes a ela. Foi determinada pela primeira vez em amostras colhidas em 1973 e correspondeu a 35% do total de amostras, sendo a segunda em ocorrência. A combinação dos genes Sr 7 a e Sr 11 continua a conferir resistência a todas as raças ocorrentes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoelho, Elisa Thomaz2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16805Pesquisa Agropecuaria Brasileira; v.12, n. único, 1977; 131-134Pesquisa Agropecuária Brasileira; v.12, n. único, 1977; 131-1341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16805/11138info:eu-repo/semantics/openAccess2014-04-15T19:09:33Zoai:ojs.seer.sct.embrapa.br:article/16805Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:09:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
