中文摘要：采用聚类分析、主成分分析和判别分析3种分析方法,对我国东南沿海5个野生波纹巴非蛤群体10个形态性状进行比较研究。聚类分析和主成分分析结果表明,广东东莞与福建厦门群体、广东湛江与海南海口群体的形态最为接近,广西北海群体的趋异程度最大。主成分分析构建了3个主成分,贡献率:主成分1为23.237%,主成分2为16.109%,主成分3为13.009%,累计贡献率为52.355%。判别分析结果表明,5群体间形态差异显著(P<0.01)。建立了5群体的判别函数,判别准确率P1为47.1%—80.0%,P2为45.7%—80.0%,5群体的综合判别率为63.8%。Mantel检验结果表明欧氏距离与地理直线距离无明显相关性(r=0.0822,P=0.3820)。广西北海群体明显地与其它4个地方分开,可能已形成一个新的亚种。本研究可为我国巴非蛤种质资源保护及遗传育种提供依据。

外文摘要：With multi-variant morphological measurement data, the author used three multivariation analysis methods （cluster analysis, principal component analysis and discriminant analysis） to study the morphological variations among five geographic populations of Paphia undulata in south China： Dongguan and Zhanjiang （Guangdong）, Xiamen （or Amoy, Fujian）, Haikou （Hainan）, and Beihai （Guangxi）. Results indicate that populations of Dongguan, Xiamen, Zhanjiang and Haikou were morphologically grouped together, leaving Beihai population alone. Significant differences were found among the five populations （P〈0.01） by discriminant analysis. The Mantel matrix tests of geographic and Euclidean dis- tances indicated no significant relationship （r = 0.0822, P = 0.3820）. As the Beihai population was shown quit different from other ones, it may have been generate a new subspecies. In general, the morphological variations of P. undulata may be resulted from a joint effect of genetics and environment. Therefore, more future works are called in molecular genetics for providing scientific basis for germ plasm resources protection and genetic breeding.
