[ 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.
