摘　　要：本研究利用微卫星标记技术，分析了4个微卫星座位多态性与皖系长毛兔1岁时的产毛量之间关系。结果表明：皖系长毛兔4个微卫星座位上平均检测到4.5（3～6）个等住基因，平均杂合度为0．680（0．630～0．721），平均多态信息含量为0.642（0．559-0.705）。Sol33微卫星座位与1岁时产毛量呈显著相关（P〈0．05），其中基因型为AD和BD个体1岁时产毛量与其他3种基因型个体间均存在显著差异（P〈0．05）。其他座位Sat4、Sat13和Sol44与皖系长毛兔1岁时产毛量相关不显著（P〉0．05）。Using microsatellite marker technology, the relationships between polymorphism of microsatellite markers and wool yield at age of one year were studied in Wan line Angora rabbits. The results showed that the average number of alleles per locus was 4.5（from 3 to 6）in Wan line Angora rabbits. The mean heterozygosity and the average polymorphism information content were 0. 680（from 0. 630 to 0. 721 ）and 0. 642（from 0. 559 to 0. 705）respectivity. The relationship was significant between Sol33 and wool yield in Sol33 locus（P 〈 0.05）, and wool yield of genotype AD and BD were significantly higher than that of other genotypes（P〈 0.05）. The relationships were no significant between Sat4, Sat13, Sol44 and ool yield （P 〉 0.05 ）.
