The female parent (i.e., the seed parent) was the `Radorg` variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the `Rader` variety (non-patented in the United States). The parentage of the new variety can be summarized as follows: `Radorg` .times.`Rader`.
