Abstract:

Chrysanthemum is one of the important species in ornamental plants to which modern biotechnology was early applied. In chrysanthemum, the technique of tissue culture was developed first in 1968 using stems as explants, and the technique of genetic transformation of chrysanthemum was developed following the discovery of sensitivity of chrysanthemum to Agribaterium in 1989. In recent twenty years, scientists have gained many achievements in genetic engineering breeding of ornamental traits, such as flower colors, inflorescence shapes, and agricultural traits, such as disease and insect resistances and abiotic stress tolerances. In this review, the achievements above were collected and analyzed, and so that to provide available information on genetic engineering breeding of chrysanthemum.

Key words: chrysanthemum (Dendranthema grandiflorum), breeding, genetic engineering, ornamental traits, agricultural trails
