Miniature rose plant named `JACnuye`

Abstract

A miniature rose plant having bright orange to orange-red flower color; pointed ovoid bud; small, two-inch flowers; and dark green, glossy, powdery mildew resistant foliage.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature rose plant class which was originated by me by crossing the variety `MACnewye`, U.S. Plant Pat. No. 5,428, with an unnamed seedling (unnamed seedling.times.MORpints).

The primary objective of this breeding was to produce a new rose variety having a miniature rose plant habit; a bright orange to orange-red color; pointed ovoid bud; small flowers two inches in diameter; and dark green, glossy, disease resistant foliage. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. A miniature (dwarf) plant habit;

2. Pointed ovoid buds;

3. Small, two-inch flowers;

4. Bright orange-red color;

5. Dark green, glossy foliage; and

6. Resistance to powdery mildew.

Asexual reproduction of this new variety by cuttings as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through suceedling propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
