Resumo: To study the inheritance as well as combining abilities for resistance to stem rot disease [Macrophomina phaseolina (Tassi) Goid.] in jute (Corchorus olitorius L.) the diallel crosses among seven varieties excluding the reciprocals were evaluated against this disease under 'sick plot' condition on the Gangetic plains of West Bengal, India during the months from May to September ('kharif' season) of 1989. Genetic analysis of the data showed that additive gene effect was predominant over nonadditive gene effect. General combining ability (gca) effect showed that the parents Russian red, Sudan green, Tanganyka and JRO-878 were the best general combiners towards desirable direction of resistance to this disease, while the specific combining ability (sca) effect was recorded to be highest in the cross Peking x JRO-7835 where both parents had undesirable gca effect. Some of the good general combiners also produced desirable sca effect in some of the cross combinations such as Russian red x JRO-878, Sudan green x JRO-878 and Tanganyka x Russian red. Average disease index of the parents and their F1 progenies further showed that resistance to stem rot pathogen M. phaseolina was dominant over susceptibility.

A análise genética dos dados mostrou que o efeito do gene aditivo predominou sobre o efeito do gene não-aditivo. A capacidade geral de combinação (cgc) mostrou que os pais Russian red, Sudan green, Tanganyka e JRO-878 foram os que melhor combinaram para obtenção de resistência a essa doença, enquanto o efeito da capacidade de combinação específica (cce) se mostrou maior no cruzamento Peking x JRO-7835, em que ambos os pais mostraram um efeito de capacidade geral de combinação (cgc) não desejado. Alguns dos combinantes gerais de boa qualidade também produziram um efeito desejável de capacidade geral de combinação em algumas das combinações, tais como na Russian red x JRO-878, Sudan green x JRO-878 e Tanganyka x Russian red. O índice médio da doença nos pais e sua progênies F1 mostrou, além disso, que o grau de resistência ao patógeno M. phaseolina era maior que o da susceptibilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDE, D.K.Kaiser, S.A.K.M.1991-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3435Pesquisa Agropecuaria Brasileira; v.26, n.7, jul. 1991; 1017-1022Pesquisa Agropecuária Brasileira; v.26, n.7, jul. 1991; 1017-10221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3435/768info:eu-repo/semantics/openAccess2010-08-19T14:09:48Zoai:ojs.seer.sct.embrapa.br:article/3435Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-19T14:09:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
