Hybrid tea rose plant named ‘MEIZOLOI’

Abstract

A new and distinct variety of hybrid tea rose plant, referred to by its cultivar name, ‘MEIZOLOI’, is disclosed. The new variety forms on a nearly continuous basis attractive, cup shaped, yellow with pink edged colored flowers. Attractive, dark green and glossy foliage is formed, which contrasts beautifully with the blossoms. An erected growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Varietal denomination—‘MEIZOLOI’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida plant was created by artificial pollination in Le Cannet des Maures, Var, France 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) was the ‘BAICENT’ variety (U.S. Pat. No. 18,102). The male parent (i.e., the pollen parent) was an unnamed seedling (non-patented).

The parentage of the new variety can be summarized as follows:
‘BAICENT’ 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.

It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

• • (a) forms yellow with pink edged colored flowers, and
  • (b) exhibits a dark green, glossy foliage.

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 ‘BAICENT’ variety (i.e., the seed parent) displays a light yellow colored flowers, whereas the new variety displays yellow with pink edged colored flowers. The unnamed seedling male parent (i.e., the pollen parent) displays dark pink colored flowers, whereas the new variety displays yellow with pink edged colored flowers. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘BAIPEACE’ variety (U.S. Plant Pat. No. 14,731) displays less flowering (blooming) and a higher plant growth habit compared to 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 softwood cuttings and grafting t-bud. 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 such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘MEIZOLOI’.

The first offer for sale of the new variety was Jan. 24, 2020 in the United States of America by the inventor or another who obtained the new variety directly or indirectly from the inventor.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2001 edition), London, England. 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 the observation of five-years-old specimens of the new variety during June while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France.
