Cultivar variation in traits affecting early nodulation of common bean

摘要: Phaseolus vulgaris L. is inferior to other grain legumes in nodulation and N 2 fixation, with early-flowering cultivars particularly limited the ability satisfy their needs through fixation. Extending period of fixation could reduce dependence this crop on N-fertilization. We sought bean accessions that were early nodulate, tried identify specific traits contributed (.)
