中甸刺玫新品种‘格桑红’和‘格桑粉’

Rosa praelucens‘Gesang Hong’and‘Gesang Fen’

‘格桑红’和‘格桑粉’是从野生中甸刺玫自然变异优良单株中驯化选育而成的新品种。‘格桑红’与原种相比花形由平瓣型变为蝶瓣型。‘格桑粉’与原种相比花色由粉红色变为粉白色。两个新品种的开花期,在云南昆明为4—5月,在香格里拉为6—7月。两个新品种的花更大,花朵更繁盛,开花时间长,提高了观赏价值。

Rosa praelucens ‘Gesang Hong＇ and R. praelucens‘Gesang Fen＇ are selected and domesticated from the natural progenies of wild R. praelucens. The flower shape of ‘Gesang Hong＇ is butterfly-type, different from the original flat-type of wild R. praelucens. The flower color of ＇Gesang Fen＇ is pinkish white and different from the original pink flower of wild R. praelucens. The new cultivars both flowered from April to May and from June to July in Kunming and Shangrila, respectively. With larger and more flourishing flowers and longer flowering time, the two new cultivars are much more valuable as ornamental plants than their original type.
