摘要: 本研究选取了绵羊基因组1号和3号染色体上的8个微卫星座位,对超细型细毛羊的232个个体的遗传多样性进行了检测。计算了各微卫星座位的等位基因频率(p)、杂合度(H)、多态信息含量(PIC)和有效等位基因数(N)。同时检测了研究样本的羊毛纤维直径(WFD),毛纤维直径离散度(FD-D),单纤维绝对强力(WAS),单纤维相对强力(WRS),强力离散(WSD),单纤维自然长度(WNL),单纤维伸直长度(WEL)和单纤维弯曲度(FW)等羊毛性状的8个表型数据。微卫星座位与羊毛性状表型数据的关联性分析结果表明,微卫星 BL-4和KRT2-13两个座位与WEL之间极显著相关(P<0.01)。微卫星Oarcp43座位与WSD之间、微卫星座位Bms1248与羊毛单纤维直径之间极显著相关(P<0.01)。座位Fcb5和OarDB6分别与FW和WAS表现出显著性关系(P<0.05)。

Abstract: In this study, the genetic diversity of 232 samples of superfine merino sheep were studied, by using eight microsatellite markers mapped to sheep chromosome 1 and chromosome 3. Allele frequencies(p), mean heterozygosity(H),polymorphisms information content(PIC), and average effective number of alleles(N)were calculated. And various phenoltype including wool fibre diameter(WFD), fibre diameter dispersion(FD-D), wool fibre absolute strength(WAS), wool fibre relative strength(WRS), wool strength disperse(WSD), wool natural length(WNL), wool extend length(WEL) and fibre waviness(FW) were measured in the flock. Correlation analysis of Microsatellite loci with wool phenotype showed: there were great correlation between microsatellite BL-4 and WEL,microsatellite KRT2-13 and WEL(P<0.01), microsatellite Oarcp43 and WSD(P<0.01),microsatellite Bms1248 and WFD(P<0.01),the correlation between microsatellite Fcb5 and FW was significant(P<0.05), microsatellite OarDB6 and WAS was significant(P<0.05).
