Abstract

A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms attractive double deep pink blossoms of good color stability. The buds are conical-shaped and very elegant. The growth habit is low compact and bushy. Decorative medium green semi-glossy foliage is formed that contrasts nicely with the deep pink blossoms. Very good disease resistance is exhibited to powdery mildew under greenhouse growing conditions.

Description

Botanical/commercial classification: Rosa hybrida/Miniature Rose Plant.
Varietal denomination: cv. Meideinis.
SUMMARY OF THE INVENTION
The new variety of Miniature rose plant was discovered during 1996 at Cannet des Maures, France while growing among plants of the ‘Meirosfon’ variety. The new variety is considered to be a spontaneous natural branch mutation of the ‘Meirosfon’ variety of unknown causation. The blossoms of the new variety displayed a distinctive clear deep pink coloration while those of the parent variety were consistently medium pink in coloration. Also, the parent variety commonly exhibits a shorter height of only approximately 30 to 35 cm at the end of the growing season. Had the new variety of the present invention not been discovered and preserved it would have been lost to mankind.
It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:
    • (a) exhibits a low compact and bushy growth habit,
    • (b) forms very elegant conical-shaped buds,
    • (c) forms in abundance attractive double deep pink blossoms of good color stability,
    • (d) forms decorative dense medium green semi-glossy foliage, and
    • (e) exhibits good resistance to powdery mildew 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 an attractive gift plant.
The new variety of the present invention can be readily distinguished from other Miniature rose varieties, such as the ‘Meidarin’ variety (U.S. Plant Pat. No. 13,291) and ‘Meishulo’ variety (U.S. Plant Pat. No. 10,015) in view of the different blossom colorations. More specifically, the ‘Meidarin’ variety displays bright orange blossoms and the ‘Meishulo’ variety displays salmon pink blossoms.
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 ‘Meideinis’ 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 nine months of age and were observed during September 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 terminology which precedes reference to the chart has been added in some instances to indicate the corresponding colors in more common terms. The description is based on the observation of nine month old specimens of the new variety which were observed during September while growing on their own roots in greenhouses at LeCannet des Maures, Var, France.
