This application claims priority to Plant Breeder's Rights Application Number 2021/2353, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 24, 2021, the contents of which are hereby incorporated by reference for all purposes.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, also an unnamed seedling. Both of the parent varieties are non-patented.
The two parents were crossed during the summer of (crossing year) and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulren040’, originated as a single seedling from the stated cross.
The new variety may be distinguished from its male pollen parent and female seed parent primarily by the following characteristics. The male pollen parent plant has pink flowers while the new variety has salmon pink flowers. While the female seed parent plant is a miniature rose, the claimed plant is a hybrid tea shrub.
The objective of the hybridization of this rose variety was to create a new and distinct variety with unique qualities, such as:
- 1. Uniform and abundant salmon pink flowers;
- 2. Vigorous, but compact growth when propagated on its own roots;
- 3. Exceptional disease resistance; and
- 4. Strong flower perfume.
This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulren040’ from all other varieties of which we are aware.
As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 2013 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulren040’ was selected in the spring of 2014 by the inventor as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘Poulren040’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2014. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulren040’ are true to type and are transmitted from one generation to the next.
DESCRIPTION OF THE DRAWING
The accompanying color illustrations show as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems, of ‘Poulren040’.
Specifically illustrated in FIG. 1 of the drawings are mature and juvenile leaves and bare stems, and a cluster of open flowers on a branch.
Specifically illustrated in FIG. 2 of the drawings are an open flower viewed from above, sepals detached revealing reproductive flower parts, flower bud and partially open flowers, and flower petals detached. Plants shown are 2 years of age.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘Poulren040’, as observed in its growth in a field nursery in Linn County, Oregon. Observed plants are 2 years of age, and were grown on their own roots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.
For a comparison, several physical characteristics of the rose variety ‘Poulen011’, U.S. Plant Pat. No. 15,167 are now compared to ‘Poulren040’. In terms of general flower tonality, the claimed plant is Red Group 49A. The comparison variety has a general flower tonality of Red Group 54D. While the claimed plant has flowers with 50 petals, the comparison variety has 80 petals.
