Dec. 19, 1972 ROSE PLANT Filed April 29, 1971 //VVE/V7'0/?. ROY L. BYRUM Wad United States Patent 3,272 ROSE PLANT Roy L. Byrum, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind. Filed Apr. 29, 1971, Ser. No. 138,724 Int. Cl. A01h 5/00 US. Cl. Plt. 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of hybrid tea rose developed as a seedling for greenhouse production of cut flowers and distinguished by the better color of its blooms over that of its parents, by the relative ease of its propagation, by its very strong resistance to disease and mildew, and by the fact that it is extremely fragrant for a hybrid rose and in comparison with most modern varieties.

BACKGROUND OF THE INVENTION This new variety of yellow rose plant has resulted from breeding eiforts carried on by me at Richmond, Indiana, with the object of developing a greenhouse cut flower production plant that would be easier to propagate and originated as a seedling of Golden Wave (RP. 2105) X Anniversary (RP. 2084) as the pollen parent. This cross was made in the hope of capturing the good qualities of both parents and at the same time finding a plant that could be more readily propagated on a commercial scale. This seedling came from a crossing made in March 1965 and the first flower was produced in October 1966. The new plant and its blooms appeared to have the desired growth and color characteristics and was therefore selected for propagation and trial. Subsequent asexual propagation of this new plant was carried on by me and under my supervision at Richmond, Ind., through successive generations and by the experience has demonstrated that the desired objective of easier propagation has been achieved.

This new variety of rose plant has also been propagated by budding at Hamilton City, Calif., and successive propagation in California and Indiana has shown that its distinguishing characteristics, including its improved coloring and growth, are firmly fixed and hold true from generation to generation.

DESCRIPTION OF THE DRAWING My new variety of rose plant is illustrated by the accompanying drawing which is a photographic representation, in full color and as closely accurate as is reasonably possible by means of conventional color reproduction materials and procedures, showing typical specimens of the bud in various stages of opening, from the time the sepals first divide, a face view of a fully opened flower, upper and underside views of mature leaves, a typical specimen of new wood with young leaves, and a typical piece of the mature wood.

Col0r.-The following describes a newly opened flower grown in greenhouse at Richmond, Ind., and blooming in August 1970: Outside, Intermediate and Inner Petals: Outside surface-Aureoline 3/1 (W) at base of petal, gradually changing to 3/2 (W) at top; Inside surface-Aureolin 3 (W) at base changing through 3/1 to 3/2 (W) at top of petal.

This new variety of rose plant not only retains the good qualities of its parents but also exhibits a better color and better foliage than its seed parent, a stronger, more uniform color than its pollen parent, and is much easier to propagate than either of its parents. The new plant is very resistant to diseases and mildew, as compared with other varieties grown under similar conditions at Richmond, Ind., and at Hamilton City, Calif, and is extremely fragrant in comparison with most modern roses.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by the more uniform and brighter yellow coloring of its blooms, its penetrating tea fragrance, its strong resistance to rose plant diseases and mildew, and the relative ease of its propagation for commercial exploitation.
