ABSTRACT: The distant hybridization was used in lodging-resistance breeding of Platycodon grandiflorus. The
parents were Platycodon grandiflorus (♀) and Campanula medium (♂). 187 seeds of F1 were harvested
by using the inter-generic hybridization in 2009 and 2010, 2 repeat, and 88 normal plants
were obtained. The characteristics of leaves, stems and branches were the same as female for F1
generation, F2 generation, backcross generation and S1 generation, and there were some different
characteristics with female which were flower colors, branching habit and plant height. A lodging-resistance plant was selected in F1, which was about 75 cm high, deep pink flower color and
developed lateral branches. The DNA groups of each generation were separated by 1% agarose gel
electrophoresis and there were not significant differences. Among the each generation many
flower colors and forms were obtained.
