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 microsatel ite 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; ③ there was no QTL affect-ing birth weight, 1.5-year weight and 2.5-year weight of Liangshan semi-fine wool sheep.
