摘要: 本试验利用7个微卫星位点分析天山雪鹅肉用品系群体的等位基因频率、有效等位基因数、平均基因杂合度、平均多态信息含量,用以评估品系的选育强度和纯度。结果显示,天山雪鹅肉用品系7个微卫星座位的平均多态信息含量为0.4979,基因组DNA呈中度多态性;平均群体杂合度为0.5367,表明该群体的遗传基础一致性较高,说明天山雪鹅肉用品系经过5个世代的群体继代选育,遗传性能趋于稳定,基因纯度已达一定的水平,但仍需根据选育目标进行进一步选育。本试验选出的CKW11、CKW14、CKW43 3个高度多态性位点,为后期进行微卫星标记与天山雪鹅生产性能的相关性分析奠定了基础。

Abstract: In order to evaluate the line’s breeding intensity and purity, this report using 7 microsatellite loci analyzed the meat line of Tianshan Snow Goose groups’ allele frequency,effective numbers of alleles,mean heterozygosity and the average polymorphism information content (PIC).The results showed that the meat line of Tianshan Snow Goose groups’ PIC was 0.4979, the genomic DNA present neutral polymorphism,and the mean heterozygosity was 0.5367.These indicated this group had highly consistency about their genetic basis,that meaned Tianshan Snow Goose through five generations succesive breeding,the genetic performance tended to stabilization; genomic purity reached a certain level.But it still needs further breeding selection according to the breeding goal.Our experiment selected out three highly polymorphic sites CKW11,CKW14,CKW43,that established the basis of relativity analysis between microsatellites sign and Tianshan Snow Goose groups’ produce performance.

Key words: microsatellite; purity; PIC; goose
