摘要
以四川凉山半细毛羊为资源参考群体,选择位于绵羊3号染色体上的9个微卫星标记,用Win QTL cart软件对凉山半细毛羊的5个体重性状进行QTL检测。结果显示:1在191家系中,检测到影响羔羊断奶重的QTL,位于110.01cM,加性效应为6.860,解释表型变异为29.3%;2在190家系中,检测到影响断奶日增重的QTL,位于227.41cM,加性效应为0.013,解释表型变异为1.7%;3未检测到影响羔羊初生重、育成体重和成年体重性状的QTL。
By using Windows QTL Cartographer v2.5 software, QTLs for five weight traits of Liangshan semi-fine wool sheep were detected based on nine microsatellite markers on chromosome 3. According to the results, ① in reference family 191, the QTL affecting weaning weight was detected at 110.01 cM with an additive effect of 6.860, explaining 29.3% of the phenotypic variance; ② in reference family 190, the QTL affecting weaning daily gain was detected at 227.41 cM with an additive effect of 0.013, explaining 1.7% of the phenotypic variance; ③there was no QTL affect- ing birth weight, 1.5-year weight and 2.5-year weight of Liangshan semi-fine wool sheep.
