Claims
It is claimed:
1. A new and distinct Rose plant named `QIR 1623` as illustrated
and described.
Description
Botanical designation: Rosa hybrida.
Cultivar denomination: `QIR 1623`.
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 1623`.
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 1623`. These
characteristics in combination distinguish `QIR 1623` as a new and
distinct Rose plant: 1. Upright and mounding plant habit. 2. Strong
lateral branches. 3. Dark green-colored leaflets. 4. Large soft
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`.
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 1623` grown in a container.
The photograph on the second sheet is a close-up view of a typical
open flower of `QIR 1623`.
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 1623`.
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
1623`.
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.degree. 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. Botanical classification: Rosa hybrida `QIR 1623`. Parentage:
