Title: Hybrid tea rose plant named Ruitulvi

Description:
SUMMARY OF THE INVENTION 
     The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was discovered by me as a natural whole plant mutation of the variety known as `Ruidriko` (U.S. Plant Pat. No. 7,362) in a controlled, cultivated planting of the parent variety in Kudelstaart, The Netherlands. The varietal denomination of the new variety is `Ruitulvi`. 
     Among the novel characteristics possessed by this new variety which distinguish it from its parent and all other varieties of which I am aware are its attractive medium pink flowers borne on a plant having the same advantageous qualities of its parent, `Ruidriko`, for production of cut flowers under glass. In contrast to the medium pink flowers of the new variety, the parent produces flowers of light peach/apricot to light pink coloration. The new variety can be reproduced through propagation by cuttings, grafting, budding and micropropagation. Flowers of the new variety are produced on long strong stems. Asexual reproduction by budding, grafting, propagation of cuttings, and micropropagation of the new variety as performed in Hazerswoude, Holland, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. 
    
    
     BRIEF DESCRIPTION OF ILLUSTRATIONS 
     The accompanying illustrations show typical specimens of the vegetative growth and flowers of the new variety 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. Colors may vary depending upon growing conditions under different climate, soil, and cultivation conditions. 
    
    
     One illustration shows cut flower form of the new variety and the other illustration shows details of the new rose variety. 
     DETAILED DESCRIPTION OF THE NEW VARIETY 
     The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Colour Chart (RHSCC) and horticultural terminology in accordance with standard terminology used in UPOV-approved horticultural guidelines. The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart. 
     Parentage: Mutation of variety `Ruidriko`. 
     Class: Hybrid tea. 
     As can be seen in the accompanying detailed illustration there is shown the top of a young shoot, 1; compound three, five and seven leaflet leaves, 2, 3, and 4 respectively; a stem, 5; buds, 6 and 7; a flower, 8, about one-third open; and a flower 9, more fully open. Also shown are flower stems 10, 11 and 12, with reproductive organs displayed. 
     The following further horticultural observations were made of specimens grown under glass in Holland. 
     Flower 
     Blooming Habit: Nearly continuous. 
     A. Bud: 
     (1) Size.--Medium. 
     (2) Form.--Ovate (before separation of sepals); urn-shaped after sepals part and petals begin to unfurl. 
     (3) Color.--As sepals divide, bud color is near 62A to 62B washing into very pale pink; deeper coloration at petal edge of bud. 
     (4) Sepals.--About same length as bud, generally simple, a few extensions. 
     (5) Peduncle.--Length -- about medium to long. Aspect -- straight. Strength -- erect, very strong. Color -- medium green. 
     B. Bloom: 
     Flower.--Large size; viewed from above -- irregularly rounded; viewed from side -- (a) side view of upper part of fully opened flower, flattened convex; (b) lower part of fully opened flower, flattened convex; large petals. 
     (1) Size.--Average size when fully expanded -- about 15 cm. 
     (2) Borne.--Singly, one to a stem.

     (4) Petalage.--Many petaled under normal conditions -- fully double, about 25 petals. 
     (5) Color.--When sepals separate and petals begin to unfurl, near 62A to 62B with near 55C to 55D washing; color of undersurface is somewhat lighter. Deeper tonality appears where petals bunch. Coloring at point of petal attachment is near 56D. Overall tonality from a distance is very attractive pink. Substantially nonfading upon aging.

     A. Stamens, filaments and anthers: 
     Arrangement and color.--Regularly arranged around styles; color of filaments is very pale yellow. 
     B. Pollen:

     C. Styles: Long, stigma above mouth of receptacle, red. 
     D. Stigmas: Positioned below anthers.
