中文摘要:

为通过杂交育种培育高产、优质、兼具观赏和油用价值于一身的凤丹牡丹新品种，收集洛阳、邵阳、亳州、菏泽、铜陵5 个种源的105 株凤丹，进行种源内和种源间的杂交试验，同时开展凤丹与观赏性状优良的中原牡丹和日本牡丹品种之间的杂交。结果表明：同种源及不同种源间的凤丹优株人工杂交，种源因素对单株种子产量影响不大；不同种源的凤丹人工杂交比自然杂交单果种子数多，但种子均重和种子大小较自然杂交略小；不同种源凤丹与7 个中原牡丹品种杂交，洛阳凤丹与香玉杂交、邵阳凤丹与玉面桃花杂交、菏泽凤丹与玉面桃花杂交、邵阳凤丹与霓虹焕彩杂交，单株种子重均超过12 g；不同种源凤丹与3 个日本牡丹品种杂交，洛阳凤丹与太阳杂交单株种子产量最高（92.64 g）。该研究为利用传统育种手段进行高产、优质、兼具观赏和油用价值的新品种选育奠定了研究基础。

英文摘要:

In order to cultivate a new oil and ornamental tree peony Paeonia ostii Fengdan with high yield and superior quality by cross breeding，105 accessions of Fengdan from five geographic sources such as Luoyang， Shaoyang，Bozhou，Heze，and Tongling were crossed within same or between different geographic sources. In addition，Fengdan were crossed with P. suffruticosa Zhongyuan Group and P. suffruticosa Japan Group with excellent ornamental traits respectively. Results indicated that geographic sources played an unimportant role in seed yield per plant. The seed number per fruit of artificial hybridization was more than that of natural hybridization，but the single seed weight and size were lightly smaller than that of natural hybridization. Fengdan in different geographic sources were crossed with 7 cultivars of P. suffruticosa Zhongyuan Group，seed yield per plant of Luoyang Fengdan × Xiangyu，Shaoyang Fengdan × Yumian Taohua，Heze Fengdan × Yumian Taohua，ShaoyangFengdan× Nihong Huancai were more than 12 g. Fengdan in different geographic sources were crossed with 3 cultivars of P. suffruticosa Japan Group，seed yield per plant of Luoyang Fengdan × Taiyang was the biggest（92.64 g）. This study has laid the research foundation to get high yield and superior quality cultivars with ornamental and oil value by traditional breeding method.
