Bedding rose plant named ‘MEITITIKA’

- THE CONARD-PYLE COMPANY

A new and distinct variety of bedding rose plant, herein referred to by its cultivar name, ‘MEITITIKA’, is provided which forms very abundantly on a nearly continuous basis attractive, flat cup shaped flowers that exhibit yellow colored at the beginning of opening to red colored at the end of opening. Attractive, semi-glossy, very dense foliage is formed, which contrasts beautifully with the blossoms. A bushy growth habit is displayed. The disease tolerance is very good, particularly against black spot. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Bedding Rose Plant.

Varietal denomination—‘MEITITIKA’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Bedding 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., the seed parent) was the ‘RADBRITE’ variety (U.S. Plant Pat. No. 17,391). The male parent (i.e., the pollen parent) was the ‘RADSWEET’ variety (U.S. Plant Pat. No. 19,032).

The parentage of the new variety can be summarized as follows:
‘RADBRITE’בRADSWEET’

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 Bedding Rose plant of the present invention possesses the following combination of characteristics:

    • (a) forms attractive, flat cup shaped, flowers which are yellow colored at the beginning of the opening to red colored at the end of opening,
    • (b) forms attractive, very dense, semi-glossy foliage,
    • (c) exhibits good tolerance to diseases, particularly against black spot, and
    • (d) is well suited for providing attractive ornamentation.

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 ‘RADBRITE’ variety (i.e., the seed parent) displays pink colored blossoms and the ‘RADSWEET’ variety (i.e., the pollen parent) displays light pink colored blossoms, whereas the new variety displays yellow colored blossoms at the beginning of opening that evolve to red colored blossoms at the end of the opening. Moreover, the new variety can be readily distinguished from related similar non-parental varieties. For example, the ‘Radsunny’ variety (U.S. Plant Pat. No. 18,562) displays yellow colored flower which remain yellow throughout the opening of the flower, whereas the new variety displays yellow colored blossoms at the beginning of opening that evolve to red colored blossoms at the end of the opening.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in 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 ‘MEITITIKA’.
