| Abstract: |
A new and distinct variety of Floribunda rose plant is provided which abundantly forms attractive semi-double blossoms commonly in the form of substantially uniform clusters which are long lasting when cut and placed in a vase. The blossoms are Rose Bengal suffused with Carmine Rose and are very stable in coloration. The plant exhibits vigorous vegetation and is semi-erect. The new variety is well adapted for greenhouse forcing and is particularly well suited for cut flower production. Good resistance to cryptogamic diseases also is exhibited. |
| Claim: |
I claim:
1. A new and distinct variety of Floribunda rose plant characterized by the following combination of characteristics:
(a) forms in abundance attractive semi-double blossoms commonly borne in substantially uniform clusters which are Rose Bengal suffused with Carmine Rose and are long lasting when cut and placed in vase,
(b) forms medium green adult wood,
(c) forms vigorous vegetation,
(d) is particularly well suited for cut flower production, and
(e) is not particularly affected by cryptogamic diseases;
substantially as herein shown and described. |
| Description: |
SUMMARY OF THE INVENTION
The new variety of Floribunda 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 Jeldaniran variety (U.S. Plant Pat. No. 5,636). The male parent (i.e., the pollen parent) of the new variety was the Sterling Silver variety (U.S. Plant Pat. No. 1,433). The parentage of the new variety canbe summarized as follows:
The seeds resulting from the above pollination were sown and 21 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 Floribunda rose plant of the present invention possesses the following combination of characteristics:
(a) forms in abundance attractive semi-double blossoms commonly borne in substantially uniform clusters which are Rose Bengal suffused with Carmine Rose and are long lasting when cut and placed in a vase,
(b) forms medium green adult wood,
(c) forms vigorous vegetation,
(d) is particularly well suited for cut flower production, and
(e) is not particularly affected by cryptogamic diseases.
The flower coloration has been found to be very stable. Also, the plant is well adapted for greenhouse forcing.
The new variety undergoes 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 from one generation toanother in both France and the United States.
The new variety has been named the Meikister variety.
BRIEF DESCRIPTION OF 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 terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on two year old specimens of the new variety during November while budded on Rosa indica understock and growing in greenhouses at Cap d'Antibes, France.
Class: Floribunda.
