摘　　要：中国美利奴超细品系育成后,利用羊毛细度14μm澳美超细公羊进行级进杂交,进一步提高羊毛细度,改进羊毛品质。本文通过对三年来收集到的各种数据进行统计分析,表明品系羊毛细度、密度在提高,羊毛细度80支以上、小弯曲、白油汗个体数量也在逐年增加,但羊毛长度、净毛率、体重、剪毛量等指标呈现不同程度下降趋势。今后,品系选育在主攻羊毛细度的同时,要注意兼顾其他性状,避免此消彼长,影响到品系育种工作的全面进展。After Chinese Merino Super-fine strain were breeded, we utilized the Australia Merino Super-fine wool ram for grading breed in order to improve the fineness and quality of wool. In this study, the researeh data were selected for statistical analysis. The results showed that the wool fineness, small curvature and white cerolein and density of new strain were all improved. However, some others character, such as wool length, clean wool ratio, weight and production of wool etc., all presented decrease tendency in different extents. Therefore, we should also pay close attention to other characters while improving the wool fineness in the breeding process of super-fine wool sheep new strain in the future.
