ROSE PLANT Filed April 24, 1974 United States Patent 4 Plant Pat. 3,729 Patented June 10, 1975 3,729 ROSE PLANT William A. Warriner, Tustin, Califi, assignor to Jackson & Perkins Company, Medford, Oreg. Filed Apr. 24, 1974, Ser. No. 463,502 int. Cl. Atilh 5/00 US. Cl. Pit-18 ll Claim The present invention relates to a new and distinct cultivar of rose plant of the hybrid tea class, which was originated by me by crossing the cultivar Bridal Pink, U.S. Plant Pat. No. 2,851, with pollen from an unnamed cultivar.

The primary objective of this breeding was to produce a cultivar particularly suitable for production of cut flowers with a color similar to that of Bridal Pink, but with larger flower buds and blooms and longer stems. This objective was fully achieved as evidenced by the following unique combination of characteristics which are outstanding in the new cultivar and which distinguish it from its parents as well as from all other cultivars of which I am aware:

1. A vigorous habit of growth.

2. Strong, long flower stems suitable for cut flowers, normally longer than those of Bridal Pink when grown in a similar environment.

3. Strong peduncles that remain stiff and erect when used as cut flowers.

4. Flower buds similar in shape and color to Bridal Pink but normally larger when grown in a similar environment.

5. A definite resistance to powdery mildew.

Asexual reproduction of the new cultivar by budding, as performed at Wasco, Calif, shows that the described characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development, 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 my new rose variety with color terminology in accordance with Wilsons Horticultural Color Chart, except where ordinary dictionary significance of color is indicated.
