Abstract:

The crossbreeding research was carried out on azalea using the multi-seasonal flowering azaleas varieties such as Carnation, Pink Ribbons and Chiffon as female parent and the Chinese native Yingshanhong (CHN1/2/3) as male parent. Statistical analyses were performed on seed quality of single capsule and seed germination rate of hybrid females, and flower type and flower color of the first hybrid generation. The results showed that Carnation had the highest affinity in crosses with CHN1/2/3, followed by Chiffon, and Pink Ribbons was the lowest; Flower colors and flower types of the first hybrid generation showed significant trait segregation, and the flower types showed dominant inheritance. The results of this study provide a good reference for the breeding of new azalea varieties.

Key words: multi-seasonal flowering azalea, crossbreeding, flower color, flower type
