This application claims priority to Plant Breeder's Rights Application Number 2022/2164, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 30, 2022, 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 2015 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah116’, 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 light red flowers while the new variety has pink flowers. The female seed parent plant has light 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 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 ‘Poulpah116’ 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 2015 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpah116’ was selected in the spring of 2016 by the inventor as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘Poulpah116’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2016. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah116’ 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 ‘Poulpah116’.
Specifically illustrated in FIG. 1 of the drawings are open flowers viewed from the side and above, flower petals detached, flower bud, and sepals detached revealing reproductive flower parts.
Specifically illustrated in FIG. 2 of the drawings are juvenile and mature leaves, juvenile and mature bare stems exhibiting prickles, and a cluster of flowers on the branch. Plants shown are 5 months of age.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘Poulpah116’, as observed in its growth in an indoor glasshouse nursery in Odense Denmark. Observed plants are 5 months of age, and were grown on their own roots in 19 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 ‘Poulpah092’, U.S. Plant Pat. No. 29,725 are compared to the claimed plant. While ‘Poulpah116’ has 98 flower petals, ‘Poulpah092’ has 45 flower petals. Open flowers of ‘Poulpah116’ have a general tonality of Red-Purple Group N57C and Red-Purple 65A while ‘Poulpah092’ is Red-Purple Group 69A. Peduncles of ‘Poulpah092’ have strong intonations of Greyed-Purple Group 183B, while the claimed plant lacks the anthocyanin pigment, remaining Yellow-Green Group 144A.
