Rose plant named ‘Empintoimp’

Abstract

A new and distinct cultivar of Rose plant named ‘Empintoimp’, characterized by its long and upright flowering stems; strong plants; dark red-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Empintoimp’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as a cut flower Rose, and hereinafter referred to by the name ‘Empintoimp’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new freely-flowering cut flower Rose varieties with attractive flower colors and excellent postproduction longevity.

The new Rose plant is a naturally-occurring whole plant mutation of Rosa hybrida ‘Empinto’, not patented. The new Rose was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Empinto’ in a controlled greenhouse environment in Aalsmeer, The Netherlands in 2008.

Asexual reproduction of the new Rose by cuttings at Aalsmeer, The Netherlands, has shown that the unique features of this new 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 ‘Empintoimp’. These characteristics in combination distinguish ‘Empintoimp’ as a new and distinct Rose cultivar:

• • 1. Long and upright flowering stems.
  • 2. Glossy dark green-colored leaves.
  • 3. Dark red yellow-colored flowers.
  • 4. Excellent postproduction longevity.
  • 5. Resistant to Powdery Mildew.

Plants of the new Rose differ from plants of the parent, ‘Empinto’, primarily in flower bud size as plant of the new Rose have taller flowers buds than plants of ‘Empinto’.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘Freedom’, not patented. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Rose differed from plants of ‘Freedom’ in the following characteristics:

• • 1. Plants of the new Rose had glossier leaves than plants of ‘Freedom’.
  • 2. Outer flower petals of plants of the new Rose did not bronze or blacken whereas outer flower petals of plants of ‘Freedom’ bronzed and blackened.
  • 3. Plants of the new Rose were resistant to Downy and Powdery Mildew whereas plants of ‘Freedom’ were not resistant to Downy and Powdery Mildew.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose.

The photograph comprises a side perspective view of typical flowering stems of ‘Empintoimp’.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the summer and early autumn in Aalsmeer, The Netherlands, in a glass-covered greenhouse and under commercial production practices. Plants had been growing for ten months when the photographs and description were taken. During the production of the plants, day temperatures averaged 20° C., night temperatures averaged 18° C. and light levels averaged 10 kilolux.
