Abstract: A new ground-cover chrysanthemum cultivar‘Yinghuo’with hardy resistance was bred from progenies of a trigeneric hybrid among AjaniaOpisthopappus and Chrysanthemum. The intergeneric hybrid using Ajania khartensis as the female parent and Opisthopappus taihangensis as the male parent further crossed continue with the Ajania × Chrysanthemum cultivar‘Jinse Qionglu’. The new cultivar was selected from this F2 progenies. This cultivar grows vigorously with a compact growth habit,and crown width reaching up to 1.5 meters. It has pink-purple flowers naturally from September to October. In addition,it has strong resistance to both cold and drought,so it is also suitable for urban and rural greening projects in regions such as Beijing-Tianjin-Hebei,Xinjiang,and Tibet,as well as for slope greening applications. Besides,it can serve as forage for restoring high-altitude grassland vegetation.
