| 摘 要： | 为探讨国家级保护鸭种群的遗传多样性和遗传分化关系,利用17个微卫星标记,对我国6个国家级保护鸭品种资源的遗传多样性进行了分析,统计了平均遗传杂合度(H)、多态信息含量(PIC)、基因多样度(FST)、平均遗传分化系数(GST)和遗传距离等。结果表明,各鸭品种的杂合度较高,除两个群体表现为显著的杂合子缺失外,其他群体均处于Hard-Weinberg平衡状态。6个鸭种群间平均FST值为17.0%,平均遗传分化系数GST为14.7%,各品种平均杂合度为0.706～0.604,平均多态信息含量(PIC)为0.561～0.663。本研究说明我国6个国家级保护鸭品种资源各品种内和品种间的遗传变异大,遗传多样性丰富。 |

| Abstract: | Seventeen microsatellite loci were used to assess the genetic variation and population structure of six endangered duck populations in China. PIC, heterozygosity with two estimators of genetic differentiation (F(ST) and G(ST)), and Nei's standard genetic distance were evaluated. The results showed that these six endangered duck populations showed high polymorphism. The proportion of inter-population subdivision among the six duck populations ranged between 17.0 and 14.7%. The average heterozygosity was 0.706, 0.702, 0.691, 0.676, 0.604, and 0.660 in the Gaoyou, Liancheng, Jinding, Beijing, Shaoxing, and Jianchang ducks, respectively. The average PIC ranged from 0.561 to 0.663. Finally, the results showed higher genetic diversity and difference above the levels of genetic variation among all the populations. |
