[Objective] The experiment aimed to carry out investigation and analysis on seed traits of white flower Platycodon grandiflorum and purple flower Platycodon grandiflorum. [Method] 13 white flower Platycodon grandiflorum and purple flower Platycodon grandiflorum from China and foreign countries were taken as research objects. Their seed traits such as seed length, seed width, thickness of seed and 1 000-grain weight were comparatively analyzed. [Result] The average seed length, average seed width, average seed thickness and average 1 000-grain weight of white flower Platycodon grandiflorum were all smaller than these of purple flower Platycodon grandiflorum. The seed length of Korean white flower Platycodon grandiflorum was relatively longer and seed lengths of other white flower Platycodon grandiflorum were all shorter than these of purple flower Platycodon grandiflorum. The seed widths of white flower Platycodon grandiflorum were smaller than these of purple flower Platycodon grandiflorum, except these of Korean white flower Platycodon grandiflorum, of white flower Platycodon grandiflorum were all smaller than these of purple flower Platycodon grandiflorum, except these of Korean Rajin and Sancheng white flower Platycodon grandiflorum. [Conclusion] The result of this experiment provided reference for rational utilizations of purple flower Platycodon grandiflorum and white flower Platycodon grandiflorum.
