摘　　要：为了探究不同杂交组合结实率与亲本亲缘关系之间的联系,了解牡丹杂交亲和性的影响因素,以16个牡丹品种为试材,进行杂交试验.并利用SRAP分子标记技术分析品种间亲缘关系.结果表明,杂交亲本的相似系数在0.31～0.35时结实率较高.针对实际育种目标,提出了牡丹亲本搭配策略,在保证满足育种要求的前提下,为获得更多的杂交种子.应尽量选择亲缘关系稍远的品种形成杂交组合.The study was performed to explore the relationship between the setting percentages and the phylogenetie relationships. The purpose was to comprehend the influence factors of hybridization affinity among Paeonia suffruticosa. Sixteen Paeonia suffruticosa varieties were used as hybrid test materials, and using SRAP molecular markers to analysis the phylogenetie relationship between varieties. The results showed that： parents with a similarity coefficient of 0.31-0.35 tended to have a high setting percentage. The methods of parental selection in actual breeding work were suggested based on the present results. To get more hybrid seeds with purpose hybrid traits, so the parent should selected of a relatively farther hybridization.
