Application No: 11/495,552  on  31 Jul 2006
Inventors: Radler; William J. (Greenfield, WI)
The female parent (i.e., the seed parent) was the `Radbrite` variety (U.S. Plant Pat. No. 17,391). The male parent (i.e., the pollen parent) of the new variety was the `Radsweet` variety (non-patented in the United States). The `Radbrite` variety is being marketed under the Brite Eyes trademark.....The description is based on the observation of two-year-old specimens of the new variety during June while growing outdoors on their own roots near West Grove, Pa., U.S.A.
