Miniature rose plant named ‘Poulpal107’

[0001] Botanical designation: Rosa hybrida.

[0002] Variety denomination: ‘Poulpal107’.

[0003] This application claims priority to Plant Breeder's Rights Application Number 2024/2189, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 19, 2024, the contents of which are hereby incorporated by reference for all purposes.

[0004] 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.

[0005] The two parents were crossed during the summer of 2017 and the resulting seeds were planted in a controlled environment in Odense, Denmark. The new variety, named ‘Poulpal107’, originated as a single seedling from the stated cross.

[0006] 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 exhibits orange-pink blended flowers while the new variety has red-purple flowers. The female seed parent plant has light pink flowers while the new variety has a distinctly different red-purple flower colour.

[0007] The objective of the hybridization of this rose variety was to create a new and distinct variety with unique qualities, such as:

• • [0008] 1. Uniform and abundant red-purple flowers;
  • [0009] 2. Vigorous, but compact growth when propagated on its own roots;
  • [0010] 3. Exceptional disease resistance; and
  • [0011] 4. Suitability for production in small containers.

[0012] This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpal107’ from all other varieties of which we are aware.

[0013] As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 2017 and conducted evaluations on the resulting seedlings in a controlled environment in Odense, Denmark. ‘Poulpal107’ was selected in the spring of 2018 by the inventor as a single plant from the progeny of the aforementioned hybridization.

[0014] Asexual reproduction of ‘Poulpal107’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Odense, Denmark in July 2018. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal107’ are true to type and are transmitted from one generation to the next.

[0018] Plants shown are 3 months old.

[0019] The following is a description of ‘Poulpal107’, as observed in its growth in a glasshouse nursery in Odense Denmark. Observed plants are 3 months of age, and were grown on their own roots in 30 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

[0020] For a comparison, several physical characteristics of the rose variety ‘Poulpah102’, U.S. Plant Pat. No. 33,136, are compared to the claimed plant. While ‘Poulpal107’ has 45 flower petals, ‘Poulpah102’ has 85 to 90 flower petals. The claimed plant has a flower diameter of 70 mm while ‘Poulpah102’ has a flower diameter of 80 mm. Open flowers of ‘Poulpal107’ are generally are Red-Purple Group N57A becoming Red-Purple Group N57D as flowers mature. The comparison variety, ‘Poulpah102’, has a general tonality of Red-Purple Group N57C.
