  abstract = {{L}ow {P} availability in the soil is a major constraint to legume production, and efforts are being made to identify legume genotypes with tolerance to low {P} and greater phosphorus use efficiency ({PUE}) for {N}-2 fixation. {C}ommon bean ({P}haseolus vulgaris {L}.) genotypes vary in their adaptation to low-{P} soils. {T}o investigate to what extent this variation may be related to {PUE} for {N}-2 fixation, six recombinant inbred lines ({RIL}s) of common bean contrasting in {PUE} for symbiotic {N}-2 fixation, namely {RIL}s 147, 115, 104, 83, 34, and 29 were studied in the field conditions during four growing seasons from 2011 to 2015. {W}e collected biomass (aboveground and belowground) at flowering stage, and both samples were analyzed {P} content. {R}esults indicate that low-{P} availability in the soil significantly limited plant growth, nodulation, and {N}-2 fixation for all common bean {RIL}s though with highest extent for common bean {RIL}s 147, 83, and 29, whereas in this soil, common bean {RIL}s 34 and 104 showed highest {PUE} for their {N}-2 fixation. {T}he genotypes with high {PUE} for {N}-2 fixation showed greater mycorrhizal-plant symbiosis activity rate than the genotypes with low {PUE} for {N}-2 fixation. {W}e also found a significant correlation between nodule biomass and nodule {P} content for all common bean {RIL}s. {W}e conclude that quantifying {PUE} for {N}-2 fixation may contribute to characterize the level of adaptation of {N}-2-fixing legumes to low-{P} soils.},
