Rose plant--Meixerul variety

Abstract

A new and distinct variety of rose plant of the Miniature Class is provided which forms fairly abundantly attractive long lasting double blossoms. The blossoms initially are azalea pink and assume at least in part an ochre coloration when blooming is finished. The plant is bushy and forms fairly vigorous vegetation. The plant is well adapted to greenhouse forcing and also performs well when grown in the garden. Additionally, the plant is not particularly affected by cryptogamic diseases.

Description

SUMMARY OF THE INVENTION

The new variety of 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) was the Meijidiro variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Meihigor variety (non-patented in the United States) by the Morberg variety (non-patented in the United States). The Meihigor variety sometimes is known as the Frenzy variety. The parentage of the new variety can be summarized as follows:

Meijidiro.times.[Meihigor.times.Morberg].

The seeds resulting from the above pollination were sown and 72 plantlets 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) forms in fair abundance attractive double long lasting blossoms which initially are azalea pink and turn at least in part to ochre when blooming is finished,

(b) forms fairly vigorous vegetation,

(c) exhibits a bushy growth habit,

(d) is well adapted to greenhouse forcing and also performs well in the garden, and

(e) is not particularly affected by cryptogamic diseases.

The new variety well meets the needs of the horticultural industry for all usages. It is particularly well-suited for use as attractive ornamentation as a flowering pot plant for use indoors or outdoors.

The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. A sexual 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 Meixerul variety.

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 to indicate the corresponding colors in common terms. The description is based on one year old specimens of the new variety which were observed during February while growing on their own roots in greenhouses at Le Cannet des Maures, Var, France.
