This application claims priority to Plant Breeder's Rights Application Number 2021/2352, 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 2013 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulren041’, 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 red flowers while the new variety has pink flowers. The female seed parent plant has red flowers while the new variety has pink flowers.
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 pink, perfumed flowers;
- 2. Vigorous, but compact growth when propagated on its own roots;
- 3. Exceptional disease resistance.
This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulren041’ 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. ‘Poulren041’ was selected in the spring of 2014 by the inventor as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘Poulren041’ 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 ‘Poulren041’ 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 ‘Poulren041’.
Specifically illustrated in FIG. 1 of the drawings are mature and juvenile leaves, and bare stems.
Specifically illustrated in FIG. 2 of the drawings are an open flower viewed from above, sepals detached, petals detached, reproductive flower parts, and a cluster of flower buds on the branch upon opening. Plants shown are 2 years of age.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘Poulren041’, as observed in its growth in an outdoor nursery in Odense Denmark. Observed plants are 24 months of age, and were grown on their own roots in 35 cm pots. 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 ‘Poulren022’, U.S. Plant Pat. No. 26,014 are compared to ‘Poulren041’. The outer petals upon opening of ‘Poulren022’ are—Upper surface: Red-Purple Group N66B. Lower surface: Red-Purple Group 67B. The outer petals upon opening of ‘Poulren041’are—Red-Purple Group N57A with light splashes of Orange Group 29B at the middle and lower zone. There are differences in the length of internodes in that ‘Poulren022’ is 40 mm, while the claimed plant internodes are 65 mm.
