| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive intense yellow blossoms that well retain their coloration. Such blossoms are long-lasting when placed in a vase and exhibit good petal-drop characteristics. The plant exhibits an erect growth habit, strong vegetation, and glossy dark green decorative foliage that contrasts well with the intense yellow blossom coloration. Additionally, the plant exhibits excellent disease resistance. |
| Claim: |
I claim:
1. A new and distinct variety of Hybrid Tea rose plant characterized by the following combination of characteristics:
(a) forms in abundance attractive long-lasting intense yellow blossoms that well retain their coloration,
(b) exhibits an erect growth habit with glossy dark green decorative foliage that contrasts well with the intense yellow blossom coloration,
(c) is well susceptible to forcing, and
(d) exhibits excellent disease resistance;
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 Meijason variety (U.S. Plant Pat. No. 5,622). The male parent (i.e., the pollen parent) was formed by the cross of the Jacblem variety (non-patented in the United States) and the Poultex variety (U.S. PlantPat. No. 6,261). 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 in abundance attractive long-lasting intense yellow blossoms that well retain their coloration,
(b) exhibits an erect growth habit with glossy dark green decorative foliage that contrasts well with the intense yellow blossom coloration,
(c) is well susceptible to forcing, and
(f) exhibits excellent disease resistance.
The new Hybrid Tea rose plant of the present invention responds well to greenhouse forcing and to cold culture conditions.
The new variety well meets the needs of the horticultural industry and is particularly well suited for cut flower production in greenhouses.
The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of thenew variety are stable and are strictly transmissible by such asexual propagation from one generation to another.
The new variety has been named the Meisinplox 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 June while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, Var, 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 while budded on Rosa indica understock and growing ingreenhouses at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart.
