以桃品种京玉和美味的正反交后代 6 9株为试材 ,采用RAPD指纹分析技术 ,获得了控制桃果实性状有毛 /无毛、白肉 /黄肉这 2个基因的RAPD分子连锁标记 ,其中多态性扩增DNA片段OPP2 0 - 2 2 0 0与果实有毛 /无毛基因的连锁遗传距离为 5.0cM ,多态性扩增DNA片段OPU0 3-850与果实白肉 /黄肉基因的连锁距离为 9 6cM。
Using RAPD fingerprinting technique, 69 peach cultivars Jingyu and delicious progenies of reciprocal crosses were used as materials to obtain RAPD markers linked with two genes, peach / hairless and white / yellow peach . The genetic distance between polymorphic amplified DNA fragment OPP2 0-2 2200 and fruit hairy / hairless gene was 5.0cM. The polymorphism amplified DNA fragment OPU0 3-850 and fruit white meat / yellow meat gene The chain distance is 9 6cM.
