In Iran, approximately 70 % of goats are bred for meat and wool. Markhoz goat is one of the most important goat breeds reared in Kurdistan and Kermanshah regions for Angora - mohair production. Previous research has introduced several QTLs affecting mohair traits in Angora goats; this study aimed to confirm QTLs controlling mohair traits on chromosomes 1, 2, 5, 13, 19, and 24. For this purpose, eight bucks with an average of 32 offspring were taken into consideration. The studied traits included fleece weight, average fiber diameter, staple length, and fine, medullated, kemp fiber percentage. Thirty microsatellite markers on chromosomes 1, 2, 5, 13, 19, and 24 were used for genotyping. Microsatellite markers were selected according to previous studies and goat genetic map, based on their distance on the chromosome. The least-squares regression method was used to locate QTLs. Five QTLs significant affecting mohair traits: two of them related to mohair weight traits; one QTL was significant for fiber features and quality, in particular for fiber diameter, staple length and kemp fiber. Two of them are reported for the first time in chromosomes 1 and 2 for kemp fiber and fleece weight traits respectively.

在伊朗，大约 70% 的山羊是为了肉和羊毛而饲养的。马霍兹山羊是库尔德斯坦和克尔曼沙阿地区为安哥拉马海毛生产而饲养的最重要的山羊品种之一。之前的研究已经介绍了几个影响安哥拉山羊马海毛性状的 QTL；本研究旨在确认控制 1、2、5、13、19 和 24 号染色体上马海毛性状的 QTL。为此，考虑了平均 32 个后代的 8 块钱。研究的性状包括羊毛重量、平均纤维直径、短纤维长度和细、有髓、坎麻纤维百分比。染色体 1、2、5、13、19 和 24 上的 30 个微卫星标记用于基因分型。根据先前的研究和山羊遗传图谱，根据它们在染色体上的距离选择微卫星标记。最小二乘回归方法用于定位QTL。五个对马海毛性状有显着影响的QTL：其中两个与马海毛重量性状有关；一个 QTL 对纤维特性和质量具有重要意义，特别是对纤维直径、短纤维长度和坎麻纤维。其中两个分别在 1 号和 2 号染色体中首次报道了坎普纤维和羊毛重量性状。
