Common bean (Phaseolus vulgaris L.) plants were grown for 21-28 days in plastic container-modified Leonard jar assemblies and placed in a controlled-environment room. The nodules on each plant were removed, counted; selected plants were repotted, grown and intercrossed to produce progenies for the next cycle of recurrent selection. Among the ten parent lines, Puebla 152 and WBR 22-34 produced the most nodules and Rio Tibagi and Negro Argel the fewest, when averaged over five experiments. An analysis of number of nodules on F1 plants resulting from crosses made in a partial diallel design among the ten parents revealed highly significants variation for general combining ability (GCA) but not for specific combining ability (SCA). After three cycles of recurrent selection for nodule number per plant, the mean nodule number was 211% of the mean for the 10 parents control. Total nodule weight on selected plants also increased, but individual nodule weight decreased. Nineteen C1 and 18 C2 lines resulting from the individual plants selected for greater nodule number, along with the ten parents and two non-nodulating soybean lines included as non-fixing check plants were grown in a single experiment in a low-N field. C2 lines on average accumulated significantly more N per plant than either the parents or C1 lines, providing evidence for increased N2 fixation measured by the N difference method. These data show that more nodules, possibly resulting from greater susceptibility to nodulation, are an important, heritable component of symbiosis and that selection for increased nodule number resulted in lines capable of fixing more atmospheric N2.
