Hybrid tea rose plant named `Ruikoowi`

A new variety of hybrid tea rose plant having pink blend flowers and suitable for growing under glass.

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 as a naturally occurring 
mutation in a controlled planting of the variety `Ruidriko`, U.S. Plant 
Pat. No. 7,362. The varietal denomination of the new variety is 
`Ruikoowi`. The new variety was isolated and asexually reproduced by 
budding. 
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 pink blend flowers borne on a floriferous plant with 
long stems and suitef for production of cut flowers under glass. The new 
variety can be reproduced through propagation by cuttings, grafting, 
budding and micropropagation. 
Asexual reproduction by budding of the new variety as performed in Holland 
shows that the foregoing and other distinguishing characteristics come 
true to form and are established and transmitted through succeeding 
propagations.

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 (R.H.S.C.C.) and horticultural terminology in accordance with 
standard terminology used in UPOV-approved horticultural guidelines. The 
terminology used in color description herein refers to plate numbers in 
the aforementioned color chart. 
Parentage: Mutation of `Ruidriko`. 
Class: Hybrid tea. 
As can be seen in the accompanying detail illustration there is shown the 
top of a compound three, five and seven leaflet leaves 1, 2 and 3 
(5-leaflet leaf) and 4, respectively; a stem, 5; buds, 6 and 7; a flower, 
8, about one-third open; and a flower, more fully open, unnumbered, shown 
between bud 6 and the one-third open flower 8. Also shown are flower stems 
10, 11 and 12, with reproduction organs displayed. The other illustration 
shows cut flower form. 
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.--Broad obovate (shape of longitudinal section just before 
separation of sepals); urn-shaped after sepals part. 
(3) Color.--As sepals divide, bud coloration exhibits near white petal 
reverse with light red/deep pink margins at petal edge, near 52A to B with 
occasional green streak. 
(4) Sepals.--Longer than green bud, generally simple to slightly foliated 
near 144A. 
(5) Peduncle.--Length -- long, about 11 cm. Aspect -- straight. Strength -- 
erect, very strong. Color -- medium green, near 137A to 137A to 137B. 
B. Bloom: 
Flower.--Large to very large size; viewed from above -- irregularly 
rounded; viewed from side -- (a) upper part of fully opened flower, 
flattened convex; (b) lower part of fully opened flower, flattened convex. 
(1) Size.--Average size when fully expanded -- about 12 to 15 cm, stem 
length about 100 cm. 
(2) Borne.--Singly, one to a stem. 
(3) Forn.--High centered, exhibition type, spiral imbricated, outer petals 
roll under, some petals quill to points. 
(4) Petalage.--Medium petaled under normal conditions -- fully double about 
27 petals; petaloids present. 
(5) Color.--When sepals part and petals begin to unfurl, light red/deep 
pink coloration of petal top surface becomes visible, ranging from 57D to 
58D; outer petals exhibit pink washing into white from petal edge toward 
petal bottom on petal upper surface; deep pink tones remain on petal edge 
on underside but pale off-white predominates on inner petals of upper 
surface until blooms age, when deep pink lightens to very pale pink. The 
pink coloration washes into the white background. Overall tonality from a 
distance is very attractive light red/deep pink with near white bicolor 
tones displayed as a pink blend. 
(6) Peduncle.--Medium number of hairs or prickles. 
(7) Fragrance.--Slight to none. 
C. Petals: 
(1) Texture.--Crisp. 
(2) Appearance.--Inside velvety and outside satiny 
(3) Form and size.--First well developed outer petals -- large, very broad, 
obovate. 
(4) Arrangement.--Regularly arranged, imbricated. 
(5) Petaloids in center.--Several. 
(6) Lasting quality.--Long lasting quality on plant and after cutting, 
about 14 days after cutting and about 20 days on the plant; petals 
persist. 
REPRODUCTIVE ORGANS 
A. Stamens, filaments and anthers: 
Arrangement and color.--Regularly arranged around styles; color filaments 
-- red. 
B. Pollen: 
Color.--Deep yellow, near 19A. 
C. Styles: Long, stigma above mouth of receptacle, red, slight to medium 
hairy. 
D. Stigmas: Red, positioned below anthers. 
E. Hip: Pitcher-shaped; large seed vessel at petal fall. 
PLANT 
A. Form: Narrow bushy, average disease resistance. 
B. Growth: Vigorous, about 200 to about 250 cm. 
C. Foliage: Compound 3, 5 and 7 leaflets. 
(1) Size.--Very large. 
(2) Quantity.--Abundant. 
(3) Color.--Foliage at time of first flowering -- light to medium green; 
juvenile foliage -- red/purple, near 178A depending on weather and method 
of cultivation; mature leaf color -- near 136A, undersurface near 136C. 
(4) Shape.--Oval, pointed. 
(5) Texture.--Upper side is slightly glossy; underside is matte. 
(6) Edge.--Serrate. 
(7) Serration.--Ordinary, acuminate apices.
