[Study of interaction of wild soybean subpopulations (Glycine soja) in the valley of the Tsukanovka river in the south of Far East of Russia].

ABSTRACT

A comparative study of the genetic structure of natural and anthropogenic populations of G. soja gives significant information about formation of different populations, and allows developing measures for preservation of unique natural gene bank of wild soybean, the species closely related to cultivated soybean. In this study, ISSR markers were used to carry out a comparative analysis of genetic structure of natural and anthropogenic subpopulations of G. soja for studying possible mutual influence of subpopulations of anthropogenic and natural phytocenosis on the formation of their genetic diversity and to study genetic structure of natural subpopulations of wild soybean in the contact places between the two types ofcenoses. As a result, the characteristics that describe the genetic diversity of studied populations have been identified and the important role of an interaction between subpopulations of different phytocenoses on formation of the spatial genetic structure of population in the valley of Tsukanovka river has been demonstrated.
