利用AFLP技术对山东沿海菲律宾蛤仔(Ruditapes philippinarum)4个野生群体(乳山、无棣、牟平、即墨)进行了遗传多样性分析。采用6对引物组合对4个群体进行扩增,共得到356个位点,乳山群体、无棣群体、牟平群体和即墨群体的多态位点比例依次为74.40%、70.50%、72.80%、74.70%,具有较高的遗传多样性水平。其中,即墨群体多态性比例最高,无棣群体多态性比例最低。聚类分析表明,各群体间的遗传距离为0.0263~0.0448,乳山群体和无棣群体间的遗传距离最近(0.0263),两群体首先聚在一起,随后与牟平群体和即墨群体聚在一起。

The AFLP technique was applied to investigate genetic diversity of 4 geographical populations of Rudi-tapes philippinarum in coastal sea of Shandong. Six primer pairs were used to generate 356 loci among individuals in 4 populations. The proportion of polymorphic loci for the Rushan, Wudi, Muping and Jimo populaton was 74.40%, 70.50%, 72.80%and 74.70%respectively, suggesting high levels of genetic diversity. The Jimo population exhibited the highest genetic diversity, and the Wudi population exhibted the lowest one. The cluster analysis showed that the genetic distance among the 4 populations was 0.0263~0.0448 and the genetic distance between the Rushan and Wudi population was the smallest one (0.0263). The Rushan and Wudi populations were clustered to-gether and subsequently grouped with Muping-Jimo clade.
