【目的】桂花(Osmanthus fragrans)四季常绿,花香浓郁,深受大众喜爱。桂花优良品种的选育可推动桂花产业发展。【方法】从广西壮族自治区桂林市永福县种植的桂花实生苗中选育获得彩叶单株,并对其无性系后代进行DUS(特异性、一致性和稳定性)测试。【结果】新品种‘南林彩锦’叶色变化明显,幼叶由初期的暗紫色变为水红、黄褐色,逐渐变为黄色,叶柄紫黑色,幼枝紫红色。【结论】该品种耐热性好,与已知彩叶品种性状均不相同,色叶观赏期长,具有很高的观赏价值。

【Objective】 Osmanthus fragrans is loved by people because of its evergreen leaves all year round and rich fragrance. Breeding new cultivars of Osmanthus fragrans can promote the development of the Osmanthus fragrans industry. 【Method】 Using seedlings as breeding materials planted in Yongfu County, Guilin City, Guangxi Zhuang Autonomous Region, a Distinctiveness, Uniformity, and Stability (DUS) test was performed on clone progenies of the single plant found. 【Result】 The leaf color of the new cultivar ‘Nanlin Caijin’ changes distinctively, and the young leaves gradually change from dark purple to water red or yellowish-brown at the initial stage. Subsequently, the leaves are yellow green, the petioles are purple black, and the shoots are red purple. 【Conclusion】 This cultivar has good heat tolerance, and different traits to the known color-leaf cultivars, whose period of ornamental leaf color is long, with outstanding ornamental potentiatilies for future markets.
