Abstract

A distinctive cultivar of miniature rose plant named ‘Ruiabri’, characterized by its dark green leaves; large double salmon-colored flowers; flowers arranged singly or in large sprays; strong rooting habit; excellent postproduction longevity; and excellent garden performance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of the miniature rose class, botanically known as Rosa hybrida, and hereinafter referred to by the cultivar name Ruiabri.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Hazerswoude, The Netherlands. The objective of the breeding program was to develop compact pot rose varieties with novel and attractive flower colors and excellent postproduction longevity and garden performance. The new cultivar originated from a cross made by the Inventor in 1994 of two unnamed proprietary seedlings, not patented. The cultivar Ruiabri was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Hazerswoude, The Netherlands. Plants of the new cultivar differ from plants of the parent selections primarily in flower color.
Asexual reproduction of the new cultivar by cuttings taken at Hazerswoude, The Netherlands, has shown that the unique features of this new miniature rose plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ruiabri’. These characteristics in combination distinguish the new miniature rose plant as a new and distinct cultivar:
1. Dark green leaves.
2. Large double salmon-colored flowers.
3. Flowers arranged singly or in large sprays.
4. Strong rooting habit.
5. Excellent postproduction longevity.
6. Excellent garden performance.
The new miniature rose plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.
BRIEF DESCRIPTION OF PHOTOGRAPHS
The accompanying colored photographs illustrate typical specimens of the vegetative growth and flowers of the new miniature rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new miniature rose.
The photograph at the top of the first sheet comprises a top perspective view of a typical plant of the new miniature rose plant grown in Hazerswoude, The Netherlands.
The photograph at bottom of the first page comprises a close-up view of a typical flower of the new miniature rose plant.
The photograph on the second sheet comprises details of the new miniature rose plant. In this photograph the apex of a young shoot (1); a leaf with three leaflets (2); a leaf with five leaflets (3); a leaf with seven leaflets (4); a stem without leaves (5); a flower bud after sepals open (6); a flower bud after petals begin to unfurl (7); a flower one-half open (8); a flower fully open (9); reproductive organs (10); a pistil (11); and receptacle (12) are shown.
DETAILED BOTANICAL DESCRIPTION
The following observations and measurements describe plants grown in Keller, Tex., in 15-cm containers under conditions which closely approximate commercial outdoor production conditions during the summer and early autumn. Plants used for the description were about 15 weeks old.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
