Miniature rose plant named ‘MEILPIQUET’

Abstract

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘MEILPIQUET’, is disclosed. The new variety forms attractive, double cream, colored flowers. Attractive glossy foliage is formed, which contrasts beautifully with the blossoms. A bushy growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida. ‘MEILPIQUET’.

Variety denomination: ‘MEILPIQUET’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was Mar. 4, 2022 in the United States of America. 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 at 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 (not patented). The male parent (i.e., the pollen parent) of the new variety was an unnamed seedling (not patented) from the cross between a different unnamed seedling (not patented) and the ‘RADTKO’ variety (U.S. Plant Pat. No. 16,202).

The parentage of the new variety can be summarized as follows:
Unnamed Seedling x (Different Unnamed Seedling x ‘RADTKO’)

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 stable and are strictly transmissible by 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 cream colored flowers,
  • (b) produces double flowers, and
  • (c) exhibits a bushy growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the unnamed seed parent displays flowers that are true intense yellow in color, whereas the new variety displays cream colored flowers. In addition, the unnamed pollen parent (Different Unnamed Seedling x ‘RADTKO’) produces lower color surface when in full bloom compared to the new variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIFERJAC’ variety (U.S. Plant Pat. No. 9,652) produces smaller sized flowers that are orange in color compared to the new variety which produces cream colored flowers. As another example, the ‘Meiskaille’ variety (U.S. Plant Pat. No. 14,274) exhibits petal color near Yellow Group 13A and produce 96 on average pistil number, whereas the new variety exhibits petal color near Yellow Group 8D when open and produces 49 on average pistil number.

The new variety has been named ‘MEILPIQUET’.
