ROSE PLANT Filed NOV. 17, 1961 INVEN TOR A TTOR/VE Y5 Plant Pat. 2,183 Patented Oct. 16, 1962 lice 2,183 ROSE PLANT Roy L. Byrum, Richmond, ind, assignor to Joseph H. Hill Company, Richmond, End, a corporation of Indiana Filed Nov. 17, 1961, Ser. No. 153,247 1 Claim. (Cl. 4761) The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the variety Topper (Plant Patent No. 1,566) with an unnamed and unpatented seedling of unidentified parentage, but which is identified in my breeding records as #539R.

The primary objective of this breeding was to produce a new rose variety which retains the flower productivity of the seed parent, Topper, but which bears flowers of improved size and color, while at the same time combining with these characteristics a more continuous flower production, with longer life of the flowers as cut flowers. In addition to the foregoing objectives, it was also my purpose to achieve greater resistance of the new variety to mildew and other rose plant diseases. These objectives were substantially achieved along with other desirable improvements, as evidenced by the following characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(1) Good growing and flower producing habits;

(2) An abundance of glossy green foliage extending Well up on the neck of the flower stems;

:(3) Relatively large flowers which are borne on strong stems of medium length;

(4) Good flower form, especially when open;

(5) Good flower fragrance;

(6) Better than average disease resistance, particularly with respect to mildew, as compared with other varieties grown under comparable cultural conditions at Richmond, Indiana;

(7) A distinctive, attractive and brilliant general color tonality of the flowers corresponding to Turkey Red in the newly open flowers, and to near Delft Rose in the three-days open flowers; and

(8) Good keeping qualities of the flowers as cut flowers.

In comparison with its seed parent, Topper, the new variety has more glossy foliage; it is more disease resistant, particularly with respect to mildew; bears larger flowers, with the flowers having short peduncles; the flowers are all of better form in both the bud and open stages and are more fragrant; the flower color is better and more brilliant; and the flowers have better keeping qualities as cut flowers.

As compared with the unnamed seedling pollen parent, the new variety is. a better grower and better flower producer.

Asexual reproduction of my new variety by grafting, as performed at Richmond, Indiana, and also by budding as performed at West Grove, Pennsylvania, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of the new variety, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as Wilson), and Kosters Color Guide (hereinafter abbreviated as Koster), except where general color terms of ordinary dictionary significance are obvious:
