| Abstract: |
A new and distinct variety of rose plant of the Miniature Class is provided which forms in abundance attractive yellow double blossoms. The blossoms are minosa yellow in coloration and are of a relatively long duration while present on the plant. The plant exhibits a vigorous growth habit which forms compact and regular vegetation. |
| Claim: |
I claim:
1. A new and distinct variety of Miniature rose plant characterized by the following combination of characteristics:
(a) forms in abundance attractive double blossoms which are mimosa yellow in coloration and of long duration on the plant, and
(b) exhibits a vigorous growth habit which results in the formation of compact and regular vegetation;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of Miniature 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 formed by crossing the Rumba variety (U.S. Plant Pat. No. 1,919) with the variety Carol Jean (U.S. Plant Pat. No. 4,277). The male parent (i.e., the pollen parent) of the new variety was formed by crossing theMeialfi variety with variety Meilucca. The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown in a greenhouse and 56 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the newvariety.
It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance attractive double blossoms which are mimosa yellow in coloration and of long duration on the plant, and
(b) exhibits a vigorous growth habit which results in the formation of compact and regular vegetation.
The new variety well meets the needs of the greenhouse floricultural industry and horticultural industry for many usages. For instance, the new variety can be grown as attractive ornamentation in parks and gardens. The resulting plant is verystrong and vigorous.
The new variety has been found to undergo asexual propagation by a number of routes, including budding, winter bench grafting, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagationfrom one generation to another.
The new variety has been named the Meijette 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 describedherein were one year old and observed during December while growing on their own roots in a greenhouse at Cannet de Maures, Var, France.

DETAILED DESCRIPTION
