摘　　要：为研究非遗传因素对新吉细毛羊主要经济性状的影响,本文运用SAS9.2软件GLM程序分析非遗传因素对新疆塔城地区新吉细毛羊9个周岁鉴定性状的影响。结果表明:出生年份对体型评分、毛长、密度评分、细度支数、细度匀度评分、弯曲评分、油汗评分、总评分有极显著影响,对头毛评分没有显著影响;群别对头毛评分、体型评分、毛长、密度评分、细度支数、细度匀度评分、弯曲评分、油汗评分、总评分均有极显著影响;性别对头毛评分、体型评分、毛长、密度评分、细度支数、细度匀度评分、弯曲评分、总评分有极显著影响,对油汗评分没有显著影响。由此可见,出生年份、群别及性别对新吉细毛羊的主要经济性状存在显著影响,因此在遗传参数估计中应综合考虑这3个因素。本研究为估计细毛羊遗传参数和育种值提供了参考依据。To study the influence of non-genetic factors on the main economic traits of Xinji fine wool sheep,In this paper, SAS9.2 software GLM program was used to analyze the influence of non-genetic factors on the identification of 9 years of the Xinji fine wool sheep in the Tacheng area of Xinjiang. Results showed that the year of birth to shape a grade, hair length, density, fineness, fineness of evenness score, bending a grade, oil khan, has remarkable effect on the total score of head hair long score did not reach significant level;The significant influence was head hair length score, body type score, hair length, density score, fineness, fineness grading, bending score, oil sweat score, and total score in this group. The significant influence was hair length score, body type score, hair length, density score, fineness, fineness, bending and total score, which had no significant effect on oil sweat score. Therefore, these three factors should be taken into consideration in the estimation of genetic parameters, so as to provide a reference for the estimation of genetic parameters and breeding values of new gemmula in taicheng region of xinjiang.
