Hybrid Tea rose plant named `Meinerau`
A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive Chartreuse Yellow blossoms that are edged with Azalea Pink. Such blossoms commonly possess a configuration that resembles that of a peony blossom. The plant exhibits medium green and glossy foliage, as well as good disease resistance. The new variety is particularly well suited for growing as attractive ornamentation in the landscape.

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 `Sunblest` variety (non-patented in the United States) and the `Korresia` variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the `Meinarval` variety (non-patented in the United States). The `Meinarval` variety sometimes is known as the `Sun King` variety. The parentage of the new variety can be summarized as follows:
(`Sunblest`.times.`Korresia`).times.`Meinarval`.
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 Chartreuse Yellow blossoms that are edged with Azalea Pink and commonly assume a configuration resembling that of a peony blossom,
(b) exhibits a bushy and compact growth habit,
(c) forms attractive medium green and glossy foliage,
(d) exhibits good disease resistance, and
(d) is particularly well suited for growing as attractive ornamentation in the landscape.
The presence of the Azalea Pink edging on the petals of the blossoms is influenced by the growing conditions. For instance, when the plant is forced such Azalea Pink coloration may be substantially absent as illustrated in some of the photographs. Accordingly, when forced the blossoms tend to lack such edging and to assume a lighter yellow coloration across both surfaces of the petals.
The new variety well meets the needs of the horticultural industry and is particularly well adapted for use as an attractive ornamental plant in an outdoors environment.
Under such growing conditions the Azalea Pink edging of the blossoms petals commonly fully develops as illustrated in FIGS. 16 and 17.
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, and is being marketed under the CENTENNIAL STAR trademark has been named the `Meinerau` variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPHSThe 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 September (except in FIGS. 16 and 17) while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France. Such blossoms of FIGS. 4 through 9 were forced. Under such growing conditions the Azalea Pink edging of the petals often is not fully developed. The blossoms illustrated in FIGS. 16 and 17 were observed during the summer in the absence of forcing and well illustrate the propensity of the petals to become edged with Azalea Pink coloration. Dimensions in centimeters are indicated at the bottom of the photograph of FIGS. 1 to 15.

DETAILED DESCRIPTIONThe 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 September while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart in some instances.
