| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided which forms attractive double long lasting blossoms which are light tangerine orange on the upper side and Chinese yellow suffused with tangerine orange on the under side. The buds and blossoms are well shaped and are of a distinctive and very attractive configuration (as illustrated). Such coloration is relatively bright and is well maintained when the blossoms are cut and placed in a vase. The plant exhibits an upright growth habit, forms vigorous vegetation, and is well suited for cut flower production. Additionally, the plant is not particularly affected by cryptogamic diseases. |
| Claim: |
I claim:
1. A new and distinct variety of Hybrid Tea rose plant characterized by the following combination of characteristics:
(a) forms attractive long lasting double blossoms which are light tangerine orange on the upper side and Chinese yellow suffused with tangerine orange on the under side,
(b) forms blossoms which well maintain their bright coloration when cut and placed in a vase,
(c) forms buds and blossoms which are of a particularly attractive configuration,
(d) exhibits vigorous vegetation,
(e) exhibits an upright growth habit,
(f) is particularly suited for cut flower production, and
(g) is not particularly affected by cryptogamic diseases;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., theseed parent) of the new variety was the product of the pollination of the Elmera variety (non-patented in the United States) by the Meirilocra variety (U.S. Pat. Plant No. 4,868). The male parent (i.e., the pollen parent) was the Keivlanox variety(non-patented in the United States). The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.
It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:
(a) forms attractive long lasting double blossoms which are light tangerine orange on the upper side and Chinese yellow suffused with tangerine orange on the under side,
(b) forms blossoms which well maintain their bright coloration when cut and placed in a vase,
(c) forms buds and blossoms which are of a particularly attractive configuration,
(d) exhibits vigorous vegetation,
(e) exhibits an upright growth habit,
(f) is particularly suited for cut flower production, and
(g) is not particularly affected by cryptogamic diseases.
The new variety well meets the needs of the horticultural industry and is particularly well suited for cut flower production.
The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. A sexual propagation by the above mentioned methods as performed in France has shown that the characteristics of thenew variety are strictly transmissible from one generation to another.
The new variety has been named the Keizoubo variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two yearsof age and were observed during November while budded on Rosa indica understock and growing in greenhouses at Cap d'Antibes, France.

DETAILED DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year old plants made during November while budded on Rose indicia understockand growing in outdoors at Cap d'Antibes, France. The coloration in common terms precedes reference to the chart.
Class: Hybrid Tea.
Plant:
Height.--Plants which were pruned to a height of 85 cm produce floral stems having a length of approximately 40 to 60 cm. When grown in a field at Wasco, Calif., one year old budded plants commonly assume a height of approximately 110 cm.

Thorns.--Size: average. Quantity: low. Color: pinkish on young stems and greenish changing to tan on mature wood.
Leaves:
Stipules.--Adnate, pectinate, fairly wide and linear.
Petioles.--Upper surface: striped reddish brown on young foliage and medium green on adult foliage with glandular edges. Under surface: light green, and bear a few prickles.
Leaflets.--Number: 3 and 5 (most often), and 7. Shape: oval to elliptic. Serration: single and regular. Texture: consistent. General appearance: dense, semi-dull foliage.
