| Abstract: |
A new and distinct variety of Hybrid Tea rose plant is provided which forms attractive pink blossoms which are lightly bicolor on the under surface. The blossoms generally are borne one per stem and exhibit long lasting qualities when cut. The new variety forces well and particularly is suited for the production of cut flowers under greenhouse conditions. |
| 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 very double pink blossoms which generally are borne one per stem,
(b) exhibits an excellent capacity for forcing, and
(c) is particularly well suited for growing under greenhouse conditions for the production of cut flowers;
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 an unintroduced variety produced by a pair of crosses. Initially the product of the cross of the Meichim variety and the Meiban variety was crossed with the Jack Frost variety (U.S. Plant Pat. No. 2,522) to producethe female parent. The male parent (i.e., the pollen parent) of the new variety was formed by crossing the Meidirapo variety with an unintroduced seedling. The parentage of the new variety can be summarized as follows:
The seeds resulting from the above pollination were sown and 28 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.
The new variety meets well the needs of the floricultural industry for all uses and is particularly suited for the production of cut flowers.
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 very double pink blossoms which generally are borne one per stem,
(b) exhibits an excellent capacity for forcing, and
(c) is particularly well suited for growing under greenhouse conditions for the production of cut flowers.
The new variety has been found to undergo asexual propagation. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.
The new variety has been named the Meivrofix 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 observedduring January while grafted on Rosa indica understock and growing in a greenhouse at Cap d'Antibes, France. The true bud and blossom colorations are more accurately depicted in FIG. 17 than in the other illustrations.

FIG. 3 illustrates a specimen of a floral bud at the opening of the sepals;
FIG. 4 illustrates a specimen of a floral bud at the opening of the petals;
