USPP8391P - Rose plant--Meizeli variety - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and continuously forms attractive semi-double long lasting pink blossoms. The blossoms are Amaranth Pink on the supper surface and light amaranth pink on the under surface. The blossoms possess a very strong fragrance and the petals tend to drop cleanly. The floral buds exhibit a very elegant exhibition-type configuration. The plant exhibits a semi-erect growth habit, forms lettuce green adult wood, forms vigorous vegetation which is very decorative, and is well suited for service as attractive ornamentation in parks and gardens. Additionally, the plant is not particularly affected by cryptogamic diseases.

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 has been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the product of the pollination of the Meirisouru variety (nonpatented in the United States) by the Meicesar variety (nonpatented in the United States). The male parent (e.i., the pollen parent) was the First Prize variety (U.S. Plant Pat. No. 2,774). The parentage of the new variety can be summarized as follows:

(Meirisouru×Meicesar)×First Prize.

The seeds resulting from the above pollination were sown and 112 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 on a continuous basis attractive long lasting semi-double pink blossoms which are Amaranth Pink on the upper surface and light Amaranth Pink on the under surface,

(b) forms floral buds which exhibit an elegant exhibition-type configuration,

(c) forms blossoms which are very fragrant,

(d) forms very decorative vigorous vegetation,

(e) exhibits a semi-erect growth habit,

(f) is particularly suited for growing in parks and gardens, and

(g) is not particularly affected by cryptogamic diseases.

The new variety well meets the needs of the horticultural industry and is particularly well suited for use as attractive ornamentation in the landscape.

The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. Asexual propagation by the above-mentioned methods as performed in France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named the Meizeli 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 September while budded on Rosa froebelli understock and growing outdoors at LeCannet-des-Maures, Var, 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 made during September while budded on Rosa froebelli understock and growing in outdoors at LeCannet-des-Maures, Var, France. The coloration in common terms precedes reference to the chart.
