USPP8493P - Miniature rose plant named `Meicupag` - Google Patents

Abstract

A new and distinct variety of rose plant of the Miniature Class is provided which abundantly and continuously forms attractive long-lasting double aureolin yellow blossoms wherein the coloration is fairly stable. The plant is very bushy and upright, and forms strong glossy dark green vegetation. The blossoms are very slightly fragrant. The plant is well adapted to greenhouse forcing while grown in small containers, and is particularly well suited for use as a flowering pot plant when grown indoors or outdoors. 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 product of the pollination of the Rise 'N Shine variety (U.S. Plant Pat. No. 4,231) by the Savamark variety (nonpatented in the United States). The male parent (i.e., the pollen parent) of the new variety was the MEITRISICAL variety (nonpatented in the United States). The parentage of the new variety can be summarized as follows:

(Rise 'N Shine×Savamark)×Meitrisical.

The seeds resulting from the above pollination were sown and 12 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 double long-lasting blossoms which are of a fairly stable aureolin yellow coloration,

(b) forms dark green glossy foliage,

(c) exhibits a very bushy and upright growth habit,

(d) is very quick to cycle,

(e) exhibits excellent garden performance and is well adapted to greenhouse forcing when grown in a container, and

(f) is not particularly affected by cryptogamic diseases.

The new variety well meets the needs of the horticultural industry. It is particularly well-suited for use as attractive ornamentation as a flowering pot plant when grown indoors or outdoors. For instance, the new variety grows well in containers.

The new variety has been found to undergo asexual propagation in France 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 Meicupag variety.
