The ?B? value, the 15N abundance of plants depending completely on biological nitrogen fixation (BNF) for growth, is required for quantifying BNF using the 15N natural abundance technique. This study aimed to investigate how common bean (Phaseolus vulgaris L.) cultivars with different growth patterns could affect the ?B? value calculated for the plant shoot. Two experiments were conducted in N-free solution. Experiment I had a factorial design with three cultivars and two rhizobium inoculants. Plants were harvested at pre-flowering stage. Experiment II was also factorial with two cultivars and two times of sampling: full flowering and mid-pod filling. Total N and δ15N analyses of different plant parts were carried out to estimate the ?B? value. There were differences between cultivars for N accumulation and 15N abundance, but no difference between rhizobium inoculants. Results revealed differences in ?B? value between cultivars of small and large seeds, the growth stage being also relevant. The ?B? values of −2.08 and −1.34? could be used for BNF estimates in small-seeded cultivars at full flowering and mid-pod filling stages, respectively, while such values should change, respectively, to −1.73 and −1.03? for large-seed cultivars. The mean ?B? value in shoots was −1.90 and −1.20? at full flowering and mid-pod filling stages, respectively. There are variations in ?B? value between cultivars of different cycle length and seed sizes, which are associated with plant architecture, thus a ?B? for each growth stage of common bean plants is required.
