United States Patent 3,166 YELLOW ROSE Robert G. Jelly, Richmond, Ind., assignor to E. G. Hill Co., Inc., Richmond, Ind. Filed Oct. 24, 1969, Ser. No. 869,402 Int. Cl. A01h 5/00 US. Cl. Plt.-24 1 Claim ABSTRACT OF THE DISCLOSURE A continuous and free blooming variety of floribunda rose plant for greenhouse culture, characterized by the very stable yellow color of its blooms, its vigorous and upright growth habit, and its improved winter productivity under low light intensities.

BACKGROUND OF THE INVENTION My new variety of rose plant was developed by me at Richmond, Ind., with the object of improving on the color and growth habit of Golden Garnette (P.P. 1,898) and to produce a yellow rose plant having a more favorable winter productivity under commercial greenhouse conditions for out flower production. The new rose plant originated as a seedling from a cross of Golden Garnette, as the seed parent, and an unnamed seedling, identified as 1-61YS in my breeding records, known to have a good winter productivity and vase life. Flowers produced, in greenhouse during February 1964, from a crossing made in October 1963, were observed to have the improved color characteristic desired and the plant was observed to have the upright growth habit, glossy foliage, and uniformity of cane that would make this variety a valuable addition to the greenhouse rose industry.

Successive asexual propagations of this new variety of rose plant by grafting under my direction at Richmond, Ind., and by budding at Livermore, Calif., have demonstrated that its distinguishing characteristics are fixed and hold true in every respect.

DESCRIPTION OF THE DRAWING My new variety of rose plant is illustrated in the accompanying photographic drawing showing typical specimens of the bud, when the sepals first divide, half opened and fully opened blooms, specimens of the wood and young leaves, and specimens of a mature leaf showing upper and under surface characteristics.

This new variety of yellow rose plant is a distinct improvement over its seed parent Golden Garnette (P.P. 1,898) in many respects. The growth of the new variety is more erect and the foliage has more gloss and eye appeal. The yellow color of the bloom is more stable than Golden Garnette with much less fading and variation; and the excellent color, texture and vase life of the blooms of the new variety, together with its uniformity of cane and better performance under the low light intensities of winter, make it a valuable addition for the greenhouse rose industry.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by its continuous and free blooming production of Aureolin Yellow flowers under greenhouse culture, its improved winter-time productivity, its more vigorous and erect growth habit, and the more stable color and longer vase life of the cut flowers.
