The method for mathematical simulation is suggested to analyze the balanced polymorphism in rhizobia population generated due to the interplay of Darwinian and frequency-dependent selection. Analysis of the model suggested that this polymorphism is determined not only by the selection pressures but also by the capacities of ecological niches occupied by bacteria in the «plant-soil» system. The model may be used for analyzing the selective processes in various symbiotic systems and for predicting the consequences of releasing of genetically modified plant symbionts into environment.
