[ Objective] To master the waterlogging tolerance of different cut rose varieties, and provide technical reference for promoting the large scale cultivation of cut rose. [Method] Using the rainfall data from September to October in Sanya, the waterlogging disasters were observed in two consecutive years, the comprehensive performance of 22 varieties and their waterlogging tolerance ability were analyzed. [ Result ] The mortality rate of Diana, Black Magic, Eric Red and Vendela was over 15%, and Diana' s was 25.7 % . Carola, Rouge Meilland, Perfume white, Lovers'Meeting, My.Choice, Tineke, Vendela, Marina, Samantha, Golden Emblem, Asagumo, Pink Fan and Double Delight can grow better and recover quickly after the disasters, and showed certain waterlogging tolerance. [Conclusion] The waterlogging tolerance of Carola, Rouge Meilland, My Choice, Tineke, Vendela, Marina, Samantha, Golden Emblem, Asagumo, Pink Fan and Double Delight was the best, and their comprehensive performance was the best, too. But the waterlogging tolerance of other major cultivars such as Black Magic, Movie Star, Tineke and Vendela was poorer.%[目的]掌握切花月季不同品种的耐湿涝性,为大面积推广切花月季提供技术参考.[方法]利用海南9 ～10月降雨自然条件,连续2年在生产上观察发生水涝灾害时22个品种的综合表现,分析品种耐涝能力.[结果]观测表明,戴安娜、黑魔术、埃里克红、芬达拉4个品种死亡率超过15％,其中戴安娜达25.7％；卡罗拉、梅兰口红、豆蔻年华、约会、我的选择、坦尼克、芬达拉、玛丽那、萨曼莎、金奖章、朝云、粉扇、红双喜13个品种灾后长势较好,能较快恢复,具有一定的耐湿涝能力.[结论]总体而言,引进的切花月季品种具备一定的耐涝能力,其中卡罗拉、梅兰口红、我的选择、坦尼克、芬达拉、玛丽那、萨曼莎、金奖章、朝云、粉扇、红双喜等11个品种耐涝能力最强,综合表现也最好,但黑魔术、影星、坦尼克和芬达拉等其他主栽品种耐涝性较差.
