| 摘 要： | 以梨品种‘黄金’（Pyrus pyrifolia Nakai‘Whangkeumbae’）与‘砀山酥’（Pyrus bretschneideri Rehd.‘Dangshansu’）的F1代杂交分离群体为试材，用分离群体分组分析法（Bulked Segregant Analysis，BSA）对果实褐皮性状进行了SSR分子标记研究。通过对源自梨和苹果基因组的281对SSR引物的筛选，获得了与梨果实褐皮性状相连锁的SSR标记CH01c06和Hi20b03，遗传连锁距离分别为4.8 cM和12.0 cM，据此，将控制该性状的基因定位在梨公共遗传图谱的LG8上。

| Abstract: | With the progenies produced from the cross Pyrus pyrifolia Nakai ‘Whangkeumbae’× Pyrus bretschneideri Rehd.‘Dangshansu’，the method of bulked segregant analysis （BSA） was used to identify molecular markers linked to the trait of fruit russet skin in pear. Two hundred and eighty one pairs of SSR primers derived from pear and apple genome were screened. Two SSR markers，CH01c06 and Hi20b03，which linked to russet skin of fruit at a distance of 4.8 cM and 12.0 cM，respectively，were obtained. This suggests that the gene which determines fruit russet skin be located on LG8 of the pear consensus genetic map. |
