Inventors: Radler; William J. (Greenfield, WI)
The new variety of shrub rose plant of the present invention was created by controlled breeding in June of 2007 in Greenfield, Wis., U.S.A., by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the `Radgold` (non-patented) variety. The male parent (i.e., the pollen parent) of the new variety was the `Radgemmis` (non-patented) variety.
...The new variety has been named `Radgardebyel`, and will be marketed under the CHAMPION YELLOW Trademark.
