Induced polyploidy has been used for decades to breed for landscape plants that are sterile and/or exhibit gigas effects. Our program continues to use induced polyploidy to breed for sterile forms of ornamentals such as Hibiscus syriacus and Acer spp. However, we have determined ploidy levels of our germplasm collection using flow cytometry and in doing so we have discovered a number of cases of natural, or at least existing, ploidy variation not previously documented. Examples from Acer spp., Cotoneaster spp., and Hibiscus syriacus will be discussed in relation to our improvement program for such traits as fertility, disease resistance, and reblooming.
