| Abstract: |
A new and distinct variety of rose plant of the Miniature Class is provided which abundantly and continuously forms elegant long lasting blossoms. The blossoms are a true white and exhibit an attractive form even when fully open. The plant is well suited for pot forcing, roots with ease, and forms particularly pleasing ornamentation when grown as a flowering pot plant either indoors or outdoors. |
| Claim: |
I claim:
1. A new and distinct variety of Miniature rose plant characterized by the following combination of characteristics:
(a) forms in abundance on a continuous basis attractive long lasting blossoms which are white in coloration and possess firm petals,
(b) forms green adult wood,
(c) exhibits a vigorous growth habit,
(d) exhibits a bushy configuration, and
(e) is well suited for pot forcing;
substantially as herein shown and described. |
| 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., theseed parent) was the Meidonq 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 Darling variety (non-patented in the United States) by the Jack Frostvariety (U.S. Plant Pat. No. 2,522) The parentage of the new variety can be summarized as follows:
Meidonq.times.[Darling.times.Jack Frost].
The seeds resulting from the above pollination were sown and 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 abundance on a continuous basis attractive long lasting double blossoms which are white in coloration and possess firm petals,
(b) forms green adult wood,
(c) exhibits a vigorous growth habit,
(d) exhibits a bushy configuration, and
(e) is well suited for pot forcing.
The new variety is particularly noteworthy for its elegant white blossoms and vigorous rate of growth.
The new variety well meets the needs of the horticultural industry for many 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. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation fromone generation to another.
The new variety has been named the Meinabron 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 describedherein were one year of age and were observed during April while growing on their own roots outdoors at Cannet-des-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 terminology which precedes reference to the chart has been added to indicate the corresponding colors in common terms. Thedescription is based on one year old specimens of the new variety during April while growing on their own roots outdoors at Cannet-des-Maures, Var, France.
