ROSE PLANT Filed Jan. 22, 1970 United States Patent 3,103 ROSE PLANT Mathias Tantau, Uetersen, Germany, assignor'to Jackson & Perkins Company, Newport Beach, Calif. Filed Jan. 22, 1970, Ser.No. 5,164 Claims priority, application Germany, Feb. '18, 1969, 45/69 S Int. Cl. A'01h /00 US. Cl. Plt.-'24 1' Claim The present invention relates to a new and distinct variety of rose plant of the floribunda'class, which was originated by me by crossing the rose variety known in Europe as Whiskey Mac (unpatented) with the rose variety'known as Zorina (U.S.' Plant Patent No. 2,321), the former being the seed parent 'andthe latter-being the pollen parent.

The primary objective of this breeding was' to produce a new and improved rose variety of the floribunda class which has a healthy and vigorous plant habit and which Ibears attractive yellow flowers in good abundance and suitable for commercial cut flower production when grown under glass. This objective was fully achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other rose varieties of which I am aware:

(1) A bushy, upright, well-branched and compact plant habit;

(2) Strong dark green foliage of medium size and which is slightly reddish green when young;

(3) Intensely bright, light golden yellow flower buds of well pointed form;

(4) Mature, densely filled, fragrant flowers of medium size and abundantly borne in clusters suitable for cut flower production under glass;

(5) A distinctive and attractive deep yellow open flower color which is retained without appreciable fading as the flowers age;

(6) Good resistance to blackspot and powdery mildew;

and

(7) Good lasting qualities of the flowers as cut flowers, with a rapid repeating habit of the flowers when grown under glass.

Asexual reproduction of my new rose variety, as performed by me by budding at Uetersen, Germany, 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 difierent 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 my new rose variety, with color terminology in accordance with Hickethiers color standards, except where general color terms of ordinary dictionary significance are obvious:
