Hybrid tea rose plant named `Meironsse`

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and continuously forms attractive double orange blossoms. The blossoms are Indian Orange and are edged with Capsicum Red. The buds assume a very elegant configuration. Such blossoms are long lasting and their cleaning ability is excellent. The plant exhibits a semi-erect growth habit, very vigorous vegetation, and is particularly well suited for growing in parks and gardens. Also, the new variety 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 with 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 Meigurami variety (non-patented in the United States) and the male parent (i.e., the pollen parent) was the product of the pollination of the Meinuzeten variety (U.S. Plant Pat. No. 4,224) by the Meinaregi variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

Meigurami.times.(Meinuzeten.times.Meinaregi).

The seeds resulting from the above pollination were sown and 39 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 double flowers which are Indian Orange and edged with Capsicum Red,

(b) exhibits a semi-erect growth habit,

(c) exhibits very vigorous vegetation,

(d) forms buds having a very elegant configuration, and

(e) is not particularly affected by cryptogamic diseases.

The cleaning ability of the blooms after flowering is excellent.

The new variety well meets the needs of the horticultural industry for a number of uses and is particularly well suited for growing as attractive ornamentation in parks and gardens.

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

The new variety has been named the Meironsse 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 three years of age and were observed during June while budded on Rosa froebelii understock and growing outdoors at LeCannet de 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 three year old plants made during June while budded on Rosa froebelii understock and growing outdoors at LeCannet des Maures, Var, France. The coloration in common terms precedes reference to the chart.
