Abstract: The five cultivars were selected from the inter-sectional hybrids between herbaceous and woody species in Paeonia genus for their typical inter-sectional hybrid traits contenting novel colors, prolonged floral longevity, and vigorous growth. Among them, ‘Jing Hua Xu Ri’ has single or lotus flowers with red petals inserted by yellow or purple stripes; ‘Jing Jun Mei’ has single flowers with yellow petals and attractive red flares; ‘Jing Hua Zhao Xia’ has single and small flowers with pink petals inserted by light yellow and light purple stripes; ‘Jing Gui Mei’ has lotus formed, pink flowers; and ‘Jing Rui Huang’ whose flowers are lotus and light yellow with light red flares, has generally some sterile carpels transformed from the stamens. They can all propagated by grafting or division.

芍药属(Paeonia)组间杂种(intersectional hybrids)是该属内牡丹组与芍药组远缘杂交产生的后代。5个新品种均为人工杂交获得,母本为‘粉云飞荷’芍药(P. lactiflora ‘Fen Yun Fei He’),父本为‘金帝’牡丹(P. ×lemoinei ‘Esperance’)。 这是我国首批通过人工杂交并获得新品种权的芍药属组间杂交新品种。

新品种特征特性

5个品种均为多年生草本,茎近地面处略木质化,有腋芽;花盘革质;生长旺盛,观赏性强。具有典型的组间杂种特点。‘京华旭日’:单枝开花2~3朵;花鲜亮红色,有不规则黄色或紫色放射状条斑;单瓣型或荷花型;单花花期6~7天,单株花期12~15天。‘京俊美’:花单生枝顶,常有1~2枚侧蕾;花乳黄色、单瓣型,花瓣基部有显著棕红色斑;单花花期6~7天,单株花期10~15天。‘京华朝霞’:花单生枝顶,常有1~2枚侧蕾;花复色、单瓣型;花瓣颜色以淡红色为主,从花心向外有不规则淡紫色或黄色放射状条纹;单花花期7天,单株花期12~15天。‘京桂美’:单枝开花2~3朵,花红色,荷花型;单花花期6~7天,单株花期12~15天。‘京蕊黄’:花单生于枝顶端,或常有1~2枚侧蕾;花淡黄色,荷花型,花瓣基部有淡红斑,部分雄蕊变态发育为不育心皮;单花花期6~7天,单株花期10~15天。

栽培技术要点与适宜栽培区域

秋季栽植在8月中旬—10月下旬裸根进行,春季栽植在3—4月芽萌动前带土球进行。繁殖在秋季进行,使用嫁接与分株方法,嫁接砧木为芍药或牡丹实生苗根。适合在华北、东北、西北地区露地栽培。
