| 摘 要： | 利用9个微卫星标记对高邮鸭、金定鸭、荆江麻鸭、山麻鸭、白羽番鸭、黑羽番鸭（纯黑）、黑羽番鸭（白头）、苏牧麻鸭、苏牧白羽鸭、苏牧黑鸭及龙白鸭11个鸭种（群）的平均基因杂合度、平均多态信息含量进行了分析。结果表明：11个鸭种（群）在9个微卫星座位上的基因频率存在一定差异．其平均基因杂合度为0．6599.平均多态信息含量为0．5966。其中．黑羽番鸭（白头）平均基因杂合度最高．为0．6948．遗传多样性最丰富；荆江麻鸭平均遗传杂合度最低，为0．5757。

| Abstract: | The allele frequencies, mean heterozygosity (H) and polymorphism information content (PIC) were studied in Gaoyou duck, Jinding duck, Jingjiang Partridge duck, San Partridge duck, White Feather Muscovy duck, Black Feather Muscovy duck, Black Feather Muscovy duck (white hair), Sumu Partridge duck, Sumu White duck, Sumu Black duck and Longbai duck using 9 microsatellite markers. The results showed that there were difference among allele frequencies of 9 microsatellite loci in 11 duck breeds, the mean heterozygosity of 11 duck breeds was 0. 659 9, and the average value of PIC was 0. 596 6. The mean heterozygosity of the Black feather Muscovy (white hair) was 0. 694 8, and that was the highest in 11 duck breeds. The mean heterozygosity of Jingjiang Partridge duck was 0. 575 7, and that was the lowest. |
