This study was performed to provide basic information of the development and breeding of new cultivars of Hibiscus syriacus L., which have more beautiful and diverse flowers. Morphological characteristics of the flowers and leaves, and genetic variation of the flowers color of two Jeoktanshim-line cultivars, Bulsae and Pyungsung, were crossed each other. The result of the cross between Bulsae and Pyungsung are as follows: Mean flower height and width were 5.35 cm and 7.69 cm, respectively. Mean length and width of petal were 5.43 cm and 3.80 cm respectively, and mean length and width of flower pistil were 4.67 cm and 0.44 cm, respectively. The flower color of all ten individuals was the color of the Jeoktanshim-line, and Pyungsung, and all flower type were I-c type.

This study was performed to provide basic information of the development and breeding of new cultivars of Hibiscus syriacus L., which have more beautiful and diverse flowers. Morphological characteristics of the leaves and genetic variation of the leaves of two Jeoktanshim-line cultivars, Bulsae and Pyungsung, were crossed each other. The result of the cross between Bulsae and Pyungsung are as follows: Mean leaf length and width were 6.09cm and 3.36cm, respectively. Mean petiole length was 1.08cm, and mean shoulder width and incision depth were 1.50cm and 0.84cm, respectively. Mean leaf base angle was $98.56^{\circ}$. Leaf index and petiole length were the most important components of leaf characteristics. Two groups were clustered in distance level 5.4. The result of the cross between Pyungsung and Bulsae are as follows: Mean leaf length and width were 5.25cm and 3.10cm, respectively. Mean petiole length was 0.87cm, and mean shoulder width and incision depth were 1.50cm and 0.76cm, respectively. Mean leaf base angle was $107.87^{\circ}$, which was the widest among ten cross combinations. Two groups were clustered with seven leaf characteristics in distance level 4.2. Group I included two small groups, and group II included four small groups.
