USPP10633P - Hybrid Tea rose plant named `Meinical` - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which forms attractive long-lasting currant red blossoms that commonly open slowly and completely. The blossom coloration commonly is stable during the course of opening. The stems are strong and the thorns tend to be few in number. The plant exhibits dark green and glossy foliage, as well as good disease resistance. The new variety is particularly well suited for cut flower production under greenhouse growing conditions.

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 `Meitulandi` variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the `Jelvanica` variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

`Meitulandi`×`Jelvanica`.

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 attractive long-lasting Current Red blossoms that commonly open slowly and completely,

(b) exhibits an erect growth habit with strong stems and few thorns,

(c) forms attractive dark green and glossy foliage,

(d) exhibits good disease resistance, and

(e) is particularly well suited for cut flower production when grown under greenhouse conditions.

When the new variety of the present invention is compared to the parent `Meitulandi` variety, it is found that the new variety unlike such parent exhibits no fragrance, possesses slightly truncated petals, and more rigid and greener foliage. When the new variety of the present invention is compared to parent `Jelvanica` variety, it is found that the new variety exhibits larger blossoms of a darker red coloration, foliage that is greener and more brilliant, and thicker stems.

The new variety well meets the needs of the horticultural industry during the commercial production of cut flowers. The blossoms commonly display a deep velvet red appearance in the absence of burning. Good color stability is manifest by the blossoms during the course of opening. Such color stability commonly is observed on the plant and when the blossoms are cut and present in a vase.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. 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.

The new variety has been named the `Meinical` 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 November while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

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 during November while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart in some instances.

Class: Hybrid Tea.
