Resumo: This work aimed at selecting cultivars for higher nodulation and biological N2 fixation (BNF) as well as for nodulation restriction with Bradyrhizobium strains established in Brazilian soils. The evaluation was done with 152 soybean genotypes. The cultivars were inoculated under environmentally controled and axenic conditions and in the absence of mineral N, with each one of the following Bradyrhizobium elkanii strains: SEMIA 5019 (=29w), SEMIA 587 and SEMIA 566. None of the cultivars tested restricted completely the nodulation, although up to four fold differences in nodule number and mass were found. General mean of total N accumulated in shoots of all cultivars with all strains was of 50.24 mg N/plant. The cultivars that showed better symbiotic performance with all strains and accumulated 30% more N than the general mean were: Bossier, BR-29, J-200, and Ivaí. The five cultivars characterized by lower BNF rates were: BR-7, EMBRAPA 9, EMGOPA-313, FT-Canarana and Paranagoiana.

Merril) com maior capacidade de nodulação e fixação biológica do N2 (FBN) e cultivares que restringem a nodulação com as estirpes de Bradyrhizobium estabelecidas nos solos brasileiros. A avaliação foi feita com 152 cultivares, infectadas sob condições ambientais controladas, axênicas e na ausência de N mineral, com uma das três estirpes de Bradyrhizobium elkanii: SEMIA 5019 (=29w), SEMIA 587 e SEMIA 566. Das cultivares analisadas, nenhuma restringiu a nodulação, embora houvesse uma diferença de até quatro vezes no número e massa de nódulos por planta. A média geral de nitrogênio acumulado na parte aérea das cultivares infectadas foi de 50,24 mg N/planta. As cultivares que apresentaram melhor desempenho simbiótico com todas as estirpes e acumularam 30% a mais de N do que a média geral foram: Bossier, BR-29, J-200 e Ivaí. As cinco cultivares que apresentaram menores taxas de FBN foram: BR-7, EMBRAPA 9, EMGOPA-313, FT-Canarana e Paranagoiana.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRegina Jacques Bohrer, TemisHungria, Mariangela1998-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4921Pesquisa Agropecuaria Brasileira; v.33, n.6, jun. 1998; 937-952Pesquisa Agropecuária Brasileira; v.33, n.6, jun. 1998; 937-9521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4921/7047info:eu-repo/semantics/openAccess2014-12-10T18:22:15Zoai:ojs.seer.sct.embrapa.br:article/4921Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-10T18:22:15Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
