Breeding Diploid New Variety from Tetraploid Cyclamen persicum Victoria Through Anther Culture

摘要

Recently in Japan market demand for cyclamen (Cyclamen persicum) has shown a preference for plants in small pots (under 12 cm) over large (over 18 cm) pots. In cyclamen, most of the flower characteristics such as bicolor, stripe, and fringe are restricted to tetraploid cultivars. Currently, the suitable cultivars for small-pot production are not tetraploids but diploids because of plant size. In addition, it is reported that the cross between tetraploid and diploid forms is very difficult in Cyclamen; even if it is successful at setting seeds, all of them are triploid. We have confirmed this by our experience and hybridization tests also.
