Özet

Genetic diversity and its geographical patterns play a very important role in species conservation and exploitation. Here, nucleotide polymorphism patterns of four single copy nuclear gene loci in wild (Glycine soja) and cultivated soybean (Glycine max) populations from different geographical regions as well as their demographic history were analyzed. The results showed that: (1) Southern subpopulation has the highest, while central subpopulation revealed the lowest genetic diversity among three Chinese G. soja subpopulations. (2) Northern Chinese G. max subpopulation depicted higher genetic diversity than other two Chinese, Korean, Japanese and American G. max subpopulations. (3) Significant genetic differentiation (P < 0.001) was observed among Chinese G. soja subpopulations from three ecological zones. There was also a significant genetic differentiation ( P < 0.01) between three Chinese and Japanese subpopulations of G. max. (4) The demographic dynamics revealed that effective population size of G. soja is expanding, while it was constant in G. max. G. soja is a useful germplasm resource to widen the genetic diversity of G. max. This study suggests that native populations of G. soja from different geo-ecological regions should be protected to conserve the genetic diversity. (C) 2015 Elsevier Ltd. All rights reserved.
