Abstract:

Waterlilies are known as “pond palettes” due to their large, beautiful, and colorful flowers. Waterlilies are widely cultivated in lakes and rivers all over the world. Coss-breeding is a common method for cultivating new varieties of waterlilies at present. Our research focused on the breeding of high-tolerance waterlily of Anecphya. The Nymphaea immutabilis with good stem erection and neat flower pattern, Nymphaea gigantea with large and blue purple flower, and Nymphaea colorata with easy dormancy, cold-resistance and abundant flowers, purple pistil were used as crossbred parents. The three waterlily species are crossed and backcrossed. After multiple generations of cross-breeding, a new variety of waterlily with well-adapted, abundant flowers and easy dormancy has been cultivated, named as Purple Luoqun.

Key words: cut waterlily, cross-subgenus hybridization, variety breeding, Purple Luoqun
