摘 要 ：以油桃(P runus p ersica L.var.nectarina)品种‘秦光’(白肉)和‘曙光’(黄肉)的89株正交F1代为试材,采用RAPD分子标记技术和BSA法寻找与桃果肉颜色基因紧密连锁的分子标记.经过对340条RAPD引物的筛选后,得到2个与桃果肉颜色性状连锁的分子标记s21-400和s486-2000.并用这两个标记结合前人已有的标记对桃果肉颜色性状进行了定位作图,发现与桃果肉颜色基因连锁距离最近的已知标记是s21-400,其图距为14 cM.
Abstract:F_1 plants of the direct cross of ‘Qinguan‘(white flesh) and ‘Shuguang‘(yellow flesh),two nectarine varieties(Prunus persica L.var.nectarina),was used at the materials to screen by RAPD and BSA(Bulk segregate analysis) the molecular markers closely linkin
