Diversity Rhizobium leguminosarum bv. trifolii field population from chernozem, pseudogley and hydromorphic black soil

Abstract

The presence of indigenous nitrogen fixing microsymbionts of leguminous plants in different type of soil are of great agricultural and environmental significance. To achieve beneficial effect of plant inoculation we need consider the characteristics of rhizobial field population. To investigate the diversity level of rhizobial population, we isolated 80 indigenius Rhizobium leguminosarum bv. trifolii from soil type chernozem, 27 from hydromorphic black soil and 92 from pseudogley. High level of genetic diversity was found among indigenous Rhizobium leguminosarum bv. trifolii population. Diversity of indigenous plant isolates from two types of soil in Serbia will be monitoring in the different enviromental conditions.
