Miniature rose plant named ‘Meijelior’

Abstract

A new and distinct variety of rose plant of the dwarf Miniature Class is provided which abundantly forms attractive double blossoms that are a blend of pale orange on the upper surface and pale pink on the undersurface. The growth habit is bushy, low and compact. Very dense medium green semi-glossy foliage is formed that contrasts nicely with the blossom coloration. The new variety is well suited for pot forcing under greenhouse growing conditions to form a distinctive gift plant. There is no particular sensitivity to diseases.

Description

Botanical/commercial classification: Rosa hybrida / Miniature Rose Plant.

Varietal denomination: cv. ‘Meijelior’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature 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 ‘Meifruije’ variety (U.S. Plant Pat. No. 9,033). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meineyta’ variety (non-patented in the United States) and the ‘Meisancho’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

‘Meifruije’×(‘Meineyta’בMeisancho’).

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 Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) exhibits a bushy, low and compact growth habit,

(b) forms in abundance attractive very double blossoms that are pale orange on the upper surface and pale pink on the under surface,

(c) forms very dense medium green semi-glossy foliage, and

(d) is well suited for pot forcing under greenhouse growing conditions.

The new variety well meets the needs of the horticultural industry. It is particularly well suited for pot forcing under greenhouse growing conditions to form a distinctive gift plant.

The new variety can be readily distinguished from its parental varieties. For instance, the ‘Meifruije’ variety forms dissimilar bright orange flowers having a yellow edge and approximately 25 to 40 petals. The flowers of the ‘Meineyta’ variety display a distinctive orange blend coloration. The ‘Meisancho’ variety is a Floribunda rose plant and displays dissimilar geranium red flowers.

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 methods as performed in the South of 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 ‘Meijelior’ 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 one year of age and were observed during May while growing on their own roots in greenhouses at LeCannet des Maures, Var, France. Dimensions in centimeters are shown 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 six month-old specimens of the new variety which were observed during November while growing on their own roots in greenhouses at LeCannet des Maures, Var, France.
