| 摘 要： | 为了调查我国海南沼虾(Macrobrachium hainanense)不同地理种群遗传多样性及遗传分化状况,本文采用序列相关扩增多态性(sequence-related amplified polymorphism,SRAP)标记对我国南方瓯江(OJ)、闽江(MJ)、珠江(PR)、万泉河(WQ)、昌化江(CH)等5个海南沼虾种群的遗传多样性进行了研究。共得到255个清晰、稳定的位点,平均多态位点比例为47.05%,由小到大依次为:PR(43.92%)=WQ(43.92%) |
| 关 键 词： | Macrobrachium hainanense SRAP 遗传多样性 遗传分化 种群遗传结构 |

| Abstract: | We studied the genetic variation and differentiation of five wild populations of Macrobrachium hainanense using SRAP markers.Samples were collected from Oujiang River(OJ), Minjiang River(MJ), Pearl River(PR), Wanquan River(WQ) and Changhuajiang River(CH).A total of 255 loci were detected, of which 47.05% were polymorphic.Proportion of polymorphic loci of the five populations ranked in the order:PR(43.92%) = WQ(43.92%) < MJ(46.67%) < CH(47.45%) < OJ(53.33%), while heterozygosity ranked as PR(0.1657) < WQ(0.1... |
