USPP9309P - Hybrid Tea rose plant named `Meiqualis` - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive bright double long-lasting dark velvet-red blossoms. The foliage is dark green and glossy and contrasts well with the blossom coloration. Long erect stems are formed that infrequently bear thorns. The new variety is particularly suited for cut-flower production under greenhouse growing conditions. Additionally, the new plant exhibits very good disease resistance.

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., the seed parent) of the new variety was the product of the cross of the Meinical variety (non-patented in the United States) and the Meired variety (U.S. Plant Pat. No. 3,452). The Meired variety sometimes is known as the Visa variety. The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Meiduitra variety (non-patented in the United States) and the Madelon variety (U.S. Plant Pat. No. 5,820). The Madelon variety is also known as the Ruimeva variety. The parentage of the new variety can be summarized as follows:

(Meinical×Meired)×(Meiduitra×Madelon)

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 Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance attractive bright double long-lasting dark velvet-red blossoms,

(b) forms attractive dark green glossy foliage,

(c) forms long erect stems that infrequently bear thorns, and

(d) is particularly suited for cut flower production.

The new variety well meets the needs of the horticultural industry and is particularly well suited for use when producing cut flowers under greenhouse conditions.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. The characteristics of the new variety have been found by such methods in France to be stable and to be strictly transmissible from one generation to another.

The new variety has been named the Meiqualis 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 two years of age and were observed during June while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants while budded on Rosa indica understock and growing during September in greenhouses at Le Cannet des Maures, France. The coloration in common terms precedes reference to the chart.
