Breeding of new ground-cover chrysanthemum cultivars with a compact plant architecture and lodging resistance
Ground-cover chrysanthemum (Chrysanthemum × morifolium Ramat.) is an important cultivar group of chrysanthemum. It is widely used in landscaping due to its resistance to cold and drought, as well as for its adaptability, and dense flowering. However, easy lodging in full bloom due to great plant heights is a common problem in ground-cover chrysanthemum cultivation and cultivars with a compact plant architecture and lodging resistance are rare. To breed a new chrysanthemum cultivar with a smaller plant height, lodging resistance, rounded type, and dense flowering, wild chrysanthemum species with prostrate growth characteristics were used as the parent and new cultivars with an ideal plant architecture were obtained through successive multiple generations of hybridization. The plants are short and compact with a plant height of 20-32 cm. They have numerous branches and dense flowering, and grow in a hemispherical shape without artificial pruning. The lodging resistance is strong. The natural flowering period is from early September to late October. No special cultivation and maintenance management is needed. The new cultivars have a great potential to be applied in landscaping and pot flower production.
