中文摘要：以随机扩增多态性DNA(RAPD)研究广西的山口、北海、犀牛角、东兴的文蛤种群的遗传多样性。结果表明 ,在筛选的60个引物中 ,23个呈阳性反应 ,其中10个引物可产生105条稳定、清晰的带。山口、北海、犀牛角、东兴的文蛤种群的遗传多样性指数分别为0.1995,0.2039,0.1773 ,0.1936;多态位点比例分别为86.32 % ,90.63% ,81.05% ,88.00% ;4个种群间的遗传距离在0.050～0.070之间 ,相邻种群的遗传差距较小。除犀牛角种群以外 。

外文摘要：Genetic diversity analysis for four populations of Meretrix respectively from Shankou,Beihai ,Xiniujiao ,Dongxing was conducted by Random Amplified Polymorphic DNA. There are 23 primes which are positive among 60 screened primes . Totally 105 bands which are stable and clear,are produced by the 10 primes among the 23 primes. The index of the genetic diversity is 0.199 5(Shankou),0.203 9(Beihai), 0.177 3 (Xiniujiao), 0.193 6 (Dongxing) respectively ;The rate of polymorphic locus is 86.32% in Shankou population,90.63% in Beihai population,81.05% in Xiniujiao population,88.00 % in Dongxing population .Genetic distances of the four populations are about 0.050～0.070. Except Xinijiao population ,the other three populations have a high level of genetic variance.
