The numbers in boldface indicate the highest proportion found for each bacterial species-plant line combination in the two experiments. The numbers of isolates were as follows: S. medicae, 51 (DZA315-16, F83-005, and JemalongA17) and 56 (PRT180-21) for soil trapping and 36 (DZA315-1), 30 (PRT180-21 and F83-005), and 42 (JemalongA17) for intraspecific competition and S. meliloti, 5 (DZA315-16), 1 (PRT180-21 and F83-005), and 8 (JemalongA17) for soil trapping and 31 (DZA315-16), 33 (PRT180-21), 32 (F83-005), and 34 (JemalongA17) for intraspecific competition.
