Abstract

There is disclosed a new variety of rose plant, particularly distinguished by its unusual range of color change from light yellowish pink to dark reddish orange of newer flowers to a moderate pink to deep pink and dark reddish orange as the blooms weather and age, a frosty white overlay also then appearing, rather short, full buds with many petals, long strong stems for cut flowers with thick waxy foliage leaflets.

Description

This application is a continuation of application Ser. No. 845,240 filed Oct. 25, 1977 now abandoned.

DESCRIPTION OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me in a breeding program which I carry on continuously and as a result involves many complex crosses generally, the instant variety of this invention being the result of crossing a seedling of the variety "First Prize", U.S. Plant Pat. No. 2,774, the seed parent hereof, with an unnamed seedling, which is identified in my records as 6742-A-33, the pollen parent, my new variety itself being identified by me as 76-R-10.

The variety which I have produced and is herein described, is new and improved, being distinguished from its parents and from all other rose varieties of which I have knowledge, as evidenced by the following unique combination of principal characteristics which are outstanding in the said new variety:

(1) Distinctive light yellowish pink to dark reddish orange coloring of the blooms which age to moderate to deep pink and dark reddish orange with white overlay;

(2) Shorter, fuller buds;

(3) Larger, more formal flowers;

(4) Reduced legginess and more closed formation of the canes;

(5) Fewer thorns; and

(6) Heavier, more waxy foliage leaflets.

Comparison of my new variety with the seed parent "First Prize" emphasizes the decidedly more orangey-pink color of the new blooms, whereas those of "First Prize" are of more pink shadings with more reddish overlay, which develops as aging progresses, whereas my new variety retains its reddish orange while a frosty white overlay appears as aging continues.

The pollen parent 6742-A-33, of my breeding, is a complex result of crosses of "Happiness" U.S. Plant Pat. No. 911, "Chrysler Imperial" U.S. Plant Pat. No. 1,167, and "El Capitan" U.S. Plant Pat. No. 1,796, thereby producing in said unnamed seedling a definite red coloring with flowers of considerably smaller size with less formal shape than my new variety. The foliage leaflets of my new variety are heavier and more waxy than those of this pollen parent.

Asexual reproduction of my new variety by budding performed by me at Chino, Calif., shows the aforementioned characteristics and distinctions come true to form, are established and transmitted through succeeding generations and propagation.

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.

Further the following detailed description of my new variety, with color terminology in accordance with Nickerson Color Fan, published by Munsell Color Company of Baltimore, Md., except where general color terms of ordinary dictionary significance are appropriate the observations having been made using incandescent daylight bulb lighting:

This description of a newly opened flower was made from a rose grown outdoors at Ontario, Calif.:

Color.--Outer petal -- outside surface -- blending up into a blend of light yellowish pink 7.5R9/3 and a combination of moderate yellowish pink 7.5R8/6 and a strong yellowish pink 7.5R7/9. Inside surface -- blending upward of light yellowish pink 7.5R9/3 into a moderate pink 5R8/6 but shades of near to a deep yellowish pink 5R6/11 and strong yellowish pink 5R7/9. Intermediate petal -- outside surface -- petal is essentially a strong reddish orange 7.5R6/12 but lighter and darker than a moderate yellowish pink 7.5R8/6.
