An initial selection for nitrogen fixation was made from 77 genotypes of common bean (Phaseolus vulgaris) adapted to Goias state, Brazil, comparing them with control genotypes with know symbiotic capacity. After several selections, the outstanding genotypes for nitrogen fixation produced 1314 kg/ha (almost three times the Brazilian average), but the treatment with mineral nitrogen was superior, suggesting the necessity of a breeding project for nitrogen fixation. Two genotypes were selected based on their capacity to fix nitrogen, productivity without nitrogen fertilizers, adaptability to Goias state and other agronomic characteristics. The two parents were evaluated in semi-controlled conditions for symbiotic capacity. The genotype WBR2255 showed better symbiotic efficiency, nodule dry weight, weight per nodule, later nodule senescence and greater tolerance to mineral nitrogen in the latter stages of growth than A295. |
