CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to Plant Breeders' Right Application No. 2024/0308, which was filed at Community Plant Variety Office in the European Union on Feb. 2, 2024, the contents of which are hereby incorporated by reference for all purposes.
STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR
The first sale or offer for sale of the new variety was Mar. 31, 2023, in France. The first offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.
BACKGROUND OF THE INVENTION
The new variety of rose plant of the present invention was created by controlled breeding in Le Cannet des Maures, Var, France 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., the seed parent) of the new variety was an unnamed seedling, which was the product of the cross between ‘MEIVILDO’ (U.S. Plant Pat. No. 6,895) and ‘DORIS TYSTERMAN’ (not patented). The male parent (i.e., the pollen parent) of the new variety was an unnamed seedling, which was the product of the cross between ‘KORBACOL’ (U.S. Plant Pat. No. 8,617) and an unnamed seedling.
The parentage of the new variety can be summarized as follows: (‘MEIVILDO’ x DORIS TYSTERMAN’) x (‘KORBACOL’ x unnamed seedling).
The seeds resulting from the above pollination were sown and 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.
The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including eye budding, softwood cuttings, semi-hardwood cuttings, and hardwood cuttings. Asexual propagation by the above-mentioned techniques in Le Cannet des Maures, Var, France has shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
SUMMARY OF THE INVENTION
It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:
- (a) forms elegant peony shaped blossoms,
- (b) displays pink colored flowers, and
- (c) exhibits dark green colored glossy foliage.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.
The new variety can be readily distinguished from its ancestors. More specifically, the seed parent displays cream grey colored flowers compared to the pink-colored flowers of the new variety. Additionally, the pollen parent displays orange-colored flowers compared to the pink colored flowers of the new variety. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the ‘MEIZINCARO’ variety (U.S. Plant Pat. No. 11,660) displays cardinal red colored blossoms compared to the pink colored blossoms of the new variety.
The new variety has been named the ‘MEILEHAGAN’ variety.
