%X Starch gel electrophoresis was used to analyze genetic structure of three populations of Oxya chinensis from Shanxi Province,China.Four allozyme polymorphic loci (MDH-1,MDH-2,LDH,ME) were found.The data suggest that two populations of O.chinensis about 41 kilometers apart are genetically similar,but differentiated from the third population with a geographic distance of 357 kilometers.However,the heterozygosity levels of those two genetically similar populations were much different.The Nei's genetic distance between two geographically close populations is 0.068,which is much smaller than those of geographically distant populations (0.23 in average).The observed overlap of geographical distance and genetic distance implies that for O.chinensis population divergence may correlate with geographic isolation.``
