摘　　要：以羊毛弯曲明显整齐度、油汗洁白度及光泽明亮度为选育性状 ,采用 5分制评分方法将这些质量指标数量化 ;通过采用群体继代选育法 ,经过 10年 4个世代选育研究 ,在中国美利奴 (新疆型 )中育成毛质优品系。品系群三个选育性状的平均评分值分别达到 4 87± 0 16、4 90± 0 19和 4 90± 0 17,较 0世代分别提高 2 7 15 %、2 7 93 %和 2 7 2 7% ;品系群平均净毛量达 3 92kg。The wool crimp,wool whiteness and the wool lightness which were graded visually by 5 grading system were selected as major traits and the multi males method was used to breed a new strain of high quality wool in Chinese Merino Sheep(Xinjiang Type); The new strain was bred up triumphantly through 10 years and 4 generations' selective breeding The grades of three selective traits in new strain were 4 87±0 16,4 90±0 19 and 4 90±0 17 respectively, and were increased by 27 15%,27 93%and 27 27%respectively from the grades of 0 generation Besides, the average clean fleece weight in new strain is 3 92 kg
