牡丹基因库营建技术研究

Study on the Establishment Technique of Peony Gene Pool

在原牡丹品种园的基础上,采取集中保存方式,重新规划圃地,划出28.67 hm^2土地营建基因库,其中8.67 hm^2为品种区（主要为中原牡丹）,包括品种展览区、品种繁殖区和新品种种植区;3.33 hm^2为野生牡丹区（含紫斑牡丹）;16.67 hm^2作为实生苗繁殖区,将每年采收的种子播种,从中选育新品种、作为砧木或药用等。重新鉴定原有品种,并拍照,登记造册,将收集的牡丹品种按色系进行分类定植,每个品种定植10--15株,对收集交流及繁育的新品种也按每个品种5--15株定植,以便于管理、观察、记载、对比及鉴定。

On the basis of former varieties garden of peony, a peony gene pool was established, according to the method of concentrated preservation. The total area was about 28.67 hectares. The varieties area （mainly Paeonia cathayana D. Y. Hong） occupied 8.67 hectares was divided into exhibiting area, breeding area and new variety planting area. The wild peony area including P. rockii occupied 3.33 hectares. The seedling breeding area occupied 16. 67 hectares. The harvested seeds were sowed, and the seedlings were used as the new varieties breeding materials, rootstocks and medicinal plants. The original varieties were identified, taken photo and registered. The collected varieties were classified based on flower color. In order to convenient management, observation, reeordation, contrast and identification, each variety were planted by 10 - 15 seedlings.
