Abstract

A new and distinct cultivar of Rose plant named ‘QIR 1621’, characterized by its upright and mounding plant habit; strong lateral branches; dark green-colored leaflets; large light pink-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘QIR 1621’.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Rose or Rosa plant, botanically known as Rosa hybrida, commercially used as a potted Rose plant and hereinafter referred to by the name ‘QIR 1621’.
The new Rose plant is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the breeding program was to develop new uniform and healthy potted Rose varieties with attractive flower colors and excellent postproduction longevity.
The new Rose plant originated from an open-pollination in March, 2013 of Rosa hybrida ‘Lys Red Klase’, not patented, as the female, or seed, parent with a unknown proprietary selection of Rosa hybrida as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor on May 19, 2014 as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Odense, Denmark.
Asexual reproduction of the new Rose plant by cuttings in a controlled greenhouse environment in Odense, Denmark since May, 2014 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 ‘QIR 1621’. These characteristics in combination distinguish ‘QIR 1621’ as a new and distinct Rose plant:
    • 1. Upright and mounding plant habit.
    • 2. Strong lateral branches.
    • 3. Dark green-colored leaflets.
    • 4. Large light pink-colored flowers.
    • 5. Flowers held upright on strong and erect peduncles.
    • 6. Good postproduction longevity.
Plants of the new Rose differ from plants of the female parent, ‘Lys Red Klase’, primarily in plant habit as plants of the new Rose are more compact and have stronger stems than plants of ‘Lys Red Klase’. In addition, flowers of plants of the new Rose are more intense pink in color than flowers of plants of ‘Lys Red Klase’.
Plants of the new Rose can be compared to plants of the Rose ‘QIR 1631’, disclosed in U.S. Plant patent application Ser. No. 15/731,447. In side-by-side comparisons, plants of the new Rose differ primarily from plants of ‘QIR 1631’ in flower color as plants of ‘QIR 1631’ have bright red purple-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.
The photograph on the first sheet comprises a side perspective view of a typical plant of ‘QIR 1621’ grown in a container.
The photograph on the second sheet is a close-up view of a typical open flower of ‘QIR 1621’.
The photograph at the top of the third sheet is a close-up view of the upper and lower surfaces of typical flowers of ‘QIR 1621’.
The photograph at the bottom of the third sheet is a close-up view of the upper and lower surfaces of typical leaves of ‘QIR 1621’.
 DETAILED BOTANICAL DESCRIPTION
Plants of the new Rose have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the autumn in a glass-covered greenhouse in Odense, Denmark and under cultural practices typical of commercial potted Rose production. Plants were grown in 13-cm containers, pinched one time and were three months old when the photographs and description were taken. During the production of the plants, day and night temperatures averaged 21° C. and light levels ranged from 60 to 100 klux. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
