利用微卫星标记对两个世代百宜黑鸡遗传多样性的研究

Study on Genetic Diversity of Two Generations Baiyi Black Chicken Using Microsatellite Markers

采用微卫星标记对百宜黑鸡第4、第5世代的遗传多样性进行研究，结果表明：10个微卫星座位在百宜黑鸡群体中的等位基因频率变化范围较大，为0．0124-0．4876。百宜黑鸡第4世代和第5世代的多态信息含量（PIC）分别为0．6649和0．6418，呈高度多态（PIC〉0．5），说明百宜黑鸡第4世代和第5世代均有丰富的遗传多样性。

Microsatellite marker was used to analysis genetic diversity of tow generations of Baiyi black chicken. The results showed that the allele frequencies of Baiyi black chicken at 10 microsatellite loci was very different from 0. 012 4 to 0. 487 6. The PIC of 4th and 5th generations of Baiyi Black Chicken were upstair polymorphism,0. 664 9 and 0. 641 8 respectively, in which were abundant genetic diversities.
