Resumo: | The common bean productivity can be improved by the increment of its capacity of nitrogen fixation in the symbiosis with bacteria of genus Rhizobium. This study had the objective to compare two breeding methodologies - F2 derived lines (LDF2) and single seed descent (SSD) in a cross among the cultivars Negro Argel (good Symbiotic N2 fixer) and Rio Tibagi (poor symbiotic N2 fixar) conducted with Rhizobium inoculation or mineral nitrogen. Eighteen families were selected on F4 in the LDF2 method based on nitrogen content in the grains and at the SSD method sixty seeds were carried out to F5 without selection. Families selected on F4 generation (LDF2) were superior for N2 fixation potential and grain yield in comparison with families that were conducted without selection (SSD) bean families selected in the F4 generation under mineral nitrogen treatment showed a tendency to respond less to inoculation then families selected under Rhizobium treatment. Furthermore, families selected under Rhizobium treatment showed better response when grown under the mineral nitrogen treatment. The same tendency was observed for families which respond to both sources of nitrogen. In this study was observed that selection under Rhizobium pressure provide a opportunity to plant breeders to select bean genotypeswith enhance nitrogen fixation potential and high grain yield. KEY-WORDS: Nodulation; total N; grain yield. |

Este estudo comparou duas metodologias de melhoramento – linhas derivadas de F2 (LDF2) e descendência de uma única semente (SSD), – em um cruzamento entre as cultivares Negro Argel (bom fixador simbiótico de nitrogênio) e Rio Tibagi (baixo potencial simbiótico de nitrogênio), com nitrogênio mineral ou inoculação com Rhizobium. Dezoito famílias foram selecionadas em F4 pelo método LDF2, com base no N total nos grãos, e sessenta sementes foram avançadas até F5 sem seleção, pelo método SSD. As famílias selecionadas em F4 (LDF2) foram superiores para o potencial de fixação de nitrogênio e produção de grãos, em comparação com famílias conduzidas sem seleção (SSD). As famílias F4 selecionadas no tratamento com nitrogênio mineral mostraram uma tendência a responder menos à inoculação, do que as famílias selecionadas no tratamento com Rhizobium. Além disso, as famílias selecionadas no tratamento com Rhizobium mostraram melhores respostas no tratamento com nitrogênio mineral. A mesma tendência foi observada para as famílias que responderam a ambas as fontes de nitrogênio. Neste estudo foi observado que a seleção sob o tratamento com Rhizobium proporciona oportunidade para os melhoristas selecionarem genótipos de feijão com potencial para aumentar afixação de nitrogênio e a produtividade de grãos.
