| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided which forms abundantly and continuously elegant double intensely golden yellow blossoms which possess a long vase life. The plant exhibits vigorous vegetation and is well suited for forcing and cut flower production. Such blooming continues well during the winter under greenhouse conditions. The plant is not particularly affected by cryptogamic diseases. |
| Claim: |
It is claimed:
1. A new and distinct variety of Hybrid Tea rose plant characterized by the following combination of characteristics:
(a) forms in abundance elegant double golden yellow blossoms,
(b) is well adapted for forcing,
(c) exhibits vigorous vegetation, and
(d) is particularly suited for cut flower production;
substantially as herein shown and described, together with the parts thereof. |
| 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 Sweet Promise variety (U.S. Plant Pat. No. 3,095) by the Meilimona variety (U.S. Plant Pat. No. 4,013). The Sweet Promise variety sometimes is called the Sonia variety. TheMeilimona variety sometimes is called the Banzai variety. The male parent (i.e., the pollen parent) was the Meirobidor variety (U.S. Plant Pat. No. 5,042). The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown in a greenhouse and 586 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of thenew 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 elegant double golden yellow blossoms,
(b) is well adapted for forcing,
(c) exhibits vigorous vegetation, and
(d) is particularly suited for cut flower production.
The new variety well meets the needs of the cut flower industry since the plant blossoms continuously and abundantly especially during the winter. It also is suited for other horticultural uses.
The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation fromone generation to another.
The new variety has been named the Meiclador 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 January while grafted on Rosa indicia and growing in a greenhouse 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 two year old plants made during January while grafted on Rosa indicia understock and growing in agreenhouse at Cap d'Antibes, France. The coloration in common terms precedes reference to the chart.
