| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided having fully double blossoms which are of an attractive intense orange coloration on the upper surfaces of the petals. The new variety is well adapted for the production of cut flowers on an abundant basis while being grown under greenhouse conditions. Once cut the blossoms ship well and exhibit good vase life. |
| Claim: |
I claim:
1. A new and distinct variety of Hybrid Tea rose plant characterized by the fact that:
(a) from the physical point of view, the plant has bronze green adult wood, an upright growth habit, and forms attractive double blossoms which are intense orange on the inner surfaces with the outer surfaces of the petals being orange fading toorange blended with pink, and
(b) from a biological point of view the plant has vigorous vegetation, flowers abundantly and continuously when grown under greenhouse conditions, and exhibits good resistance to diseases,
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new and distinct variety of Hybrid Tea rose plant of the invention was created by artificial pollination wherein two parents were crossed which previously had been studied for the characteristics sought. The seed parent resulted from theartificial pollination of the Meidanu variety (non-patented) by the product of the artificial pollination of the Meihand and Meialfi varieties (each non-patented). The pollen parent of the new variety was an unnamed seedling. The parentage of the newvariety can be summarized as follows:
The seeds resulting from the above pollination were sown and plantlets 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. Thedesirable qualities of the new variety have been confirmed through extensive testing, and the importance of the new variety has been firmly established.
It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:
(a) from the physical point of view, the plant has bronze green adult wood, an upright growth habit, and forms attractive double blossoms which are intense orange on the inner surfaces with the outer surfaces of the petals being orange fading toorange blended with pink, and
(b) from a biological point of view the plant has vigorous vegetation, flowers abundantly and continuously when grown under greenhouse conditions, and exhibits good resistance to diseases.
The new variety is well adapted to grow under greenhouse conditions where it can be relied upon to force well and to abundantly yield attractive orange blossoms.
The blossoms of the new variety have been found to exhibit good shipping qualities, and to exhibit a good vase life.
The new variety has been found to undergo asexual propagation by a number of means and may be grown on any one of a number of rootstocks. The characteristics of the new variety have been found to be strictly transmissible by such asexualpropagation from one generation to another.
The rose plant of the new variety has been named the Meirope 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 plant parts of the new variety when observed during September. The rose plants of thenew variety described herein were grown at Cap d'Antibes, France, in a greenhouse and were grafted on Rosa indica rootstock.

DETAILED DESCRIPTION
The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology preceding the numbered references has been added to designate in common terms the corresponding colors. The roseplants of the new variety described herein were grown at Cap d'Antibes, France, in a greenhouse while grafted on Rosa indicia rootstock and were observed during September.
