摘要: 利用AFLP标记对超细型细毛羊品系纯度进行检测,旨在为评价该品系细毛羊的遗传特性,采用TaqⅠ和EcoRⅠ双酶切,利用6对引物对24只细毛羊基因组DNA进行分析,共获得226个AFLP标记,1对引物获得的标记数在29~50之间,新吉超细型细毛羊相似系数AFLP研究结果为0.914~0.982,本研究为评价新吉超细型细毛羊遗传稳定系数提供了相关的参数。

Abstract: We reported the application of AFLP markers to detect genetic polymorphic loci Xinji superfine wool sheep and their amplified APLP results. Their genetic construction of the population was also analyzed. Six APLP primers were used, genomic DNA from 24 sheep were restrictive by TaqⅠand EcoRⅠ,226 AFLP markers were obtained, the obtain marker numbers of individual primer were between 29 and 50. The results indicated as the following: AFLP marker was suitable for analysis genetic polymorphism in sheep, and the similarity index of population in Xinji superfine wool sheep was 0.914 to 0.982.The study provideed an useful parameter with appraise genetic stability of Xinji superfine wool sheep.

Key words: superfine merino sheep; genetic construction of population; molecular marker; AFLP
