USPP7376P - Rose plant--Meivouplix variety - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive fully double lemon yellow blossoms. Such blossoms are long lasting. The plant exhibits an erect growth habit, vigorous vegetation, and is well suited for greenhouse forcing for cut flower production. Additionally, the plant exhibits excellent 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 Dr. Verhage variety (nonpatented in the United States). The male parent (i.e., the pollen parent) was the Meitakilor variety (nonpatented in the United States). The parentage of the new variety can be summarized as follows:

[Dr. Verhage variety×Meitakilor variety].

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biololgically 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 long lasting fully double lemon yellow blossoms,

(b) exhibits an erect growth habit,

(c) is well adapted for greenhouse forcing,

(d) exhibits vigorous vegetation,

(e) is particularly suited for cut flower production, and

(f) exhibits excellent disease resistance.

The blossom coloration is fairly well maintained during the vase life of the cut flowers.

The new variety well meets the needs of the horticultural industry for all uses and is particularly well suited for cut flower production.

The new variety has been found to undergo asexual propagation 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 Meivouplix 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 indicia undertook and growing in greenhouses at Cap d'Antibes, 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 November while budded on Rosa indicia understock and growing in greenhouses at Cap d'Antibes, France. The coloration in common terms precedes reference to the chart.
