应用淀粉凝胶电泳对山西省太原黄陵村、临猗县赵村及永济县伍姓湖3个中华稻蝗(Oxya chinensis)种群的4个等位酶位点(MDH-1、MDH-2、LDH、ME)进行了分析.结果表明3个种群的中华稻蝗在遗传结构上具有差异:黄陵种群的MDH-1、MDH-2以及伍姓湖种群的MDH-1均为单态位点;赵村种群的杂合性最低(H=0.112),伍姓湖种群最高(H=0.229);赵村种群与伍姓湖种群间的Nei's遗传距离为0.068,可视为1个大的种群,而黄陵种群与赵村种群和伍姓湖种群的Nei's遗传距离分别为0.247和0.218.考虑到赵村和伍姓湖之间的地理距离(41 km)比太原黄陵(357 km)要近得多,结果提示3个种群地理距离与遗传结构差异之间存在相关关系.

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.``
