Chrysanthemum(Dendranthema morifolium), is one of the most important floricultural crops in cut flower, potted plant and garden plant. Many chrysanthemum cultivars are weak resistant to disease, insect, virus and environment. But in allied genera, many wild species possess elite attributes such as resistance to biotic or abiotic stresses. In this paper, intergeneric cross has been made to assess the relationships between Dendranthema wild species (♀) and C. chinense (2n=18;(?)), A. myriantha (2n=18;(?)), T....
