Transgenic chrysanthemums (Chrysanthemum morifolium) with blue flower colors have already been created, and are expected to be commercialized. However, cultivated chrysanthemums are known to cross with wild species native to Japan, and careful studies are needed to assess the risk of these transgenes escaping into wild Chrysanthemum populations. We previously reported on the transmission of transgenes from the model cultivar ‘Taihei’ to interspecific progeny. For this study, we used the recently developed cultivar ‘Sei Arabella’ and a promising breeding strain (T37) as transgene hosts, and performed crosses between these lines and the wild species Chrysanthemum japonense var. japonense. We found relatively high seed set rates (20.6%–83.4%) after artificial, reciprocal pollinations, and the inheritance and segregation of the transgenes in the hybrid progeny were confirmed by PCR. Some of the transgenic progeny exhibited blue flower colors and contained modified anthocyanins, like their transgenic parents. These results were similar to those obtained with ‘Taihei’ and thus suggested that the risk of transgenes escaping to wild species could be quite high. Therefore, it will be important to investigate techniques to reduce this risk.
