Abstract: Following the discovery of chrysanthemum sensitivity to Agrobacterium in 1989，the
technique of Agrobacterium-mediated genetic transformation has been successfully used in improvement
of traits such as flower color，plant style，flowering time，disease-insect resistance and abiotic stress
tolerance. In this review，the advances of Agrobacterium-mediated genetic transformation in chrysanthemum
were summarized，including Agrobacterium strains，explants for infection，the addition of chemical
compounds and selection markers. Also，the improvement of traits，exploration of important genes was
reviewed and the perspective of enhancing transformation efficiency and developing environment-friendly
transgenic technology were discussed. The main goal is to provide reference for molecular breeding of
chrysanthemum.
