Abstract

A new garden rose plant of the Miniature class which has abundant, orange-red flowers and dark green foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

[0001] Botanical designation: Rosa hybrida.

[0002] Variety denomination: ‘Poulpal106’.

[0003] This application claims priority to Plant Breeder's Rights Application Number 2024 / 2188, 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.SUMMARY OF THE INVENTION

[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 2015 and the resulting seeds were planted in a controlled environment in Odense, Denmark. The new variety, named ‘Poulpal106’, 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 flowers with a general tonality of Red Group 40A. The new variety has a distinctly different flower colour of Red Group 43C. The male pollen parent plant grows to a mature height of 80 cm, while the new variety is very compact, growing only 30 cm in height. The female seed parent plant has Red Group 46B flowers with intonations of Red-Purple 61A, while the new variety has Red Group 43C flowers.

[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 orange-red flowers;

[0009] 2. Compact growth when propagated on its own roots;

[0010] 3. Suitability for production in small containers; and

[0011] 4. Exceptional disease resistance.

[0012] This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpal106’ 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 2015 and conducted evaluations on the resulting seedlings in a controlled environment in Odense, Denmark. ‘Poulpal106’ was selected in the spring of 2016 by the inventor as a single plant from the progeny of the aforementioned hybridization.

[0014] Asexual reproduction of ‘Poulpal106’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Odense, Denmark in July 2016. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal106’ are true to type and are transmitted from one generation to the next.DESCRIPTION OF THE DRAWING

[0015] The accompanying color illustration shows, 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 ‘Poulpal106’.

[0016] Specifically illustrated in the drawing are open flowers at various stages of development, a cluster of open flowers, demonstrating the abundance of flowers on a branch, sepals and flower petals detached revealing reproductive flower parts, an un-opened flower bud, bare stem exhibiting prickles, mature leaves viewed from above and underneath, and a juvenile leaf exhibiting anthocyanin.

[0017] Plants shown are 3 months old.DETAILED DESCRIPTION OF THE VARIETY

[0018] The following is a description of ‘Poulpal106’, 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 17 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

[0019] For a comparison, several physical characteristics of the rose variety ‘Poulpal062’, U.S. Plant Pat. No. 28,168, are compared to the claimed plant. While ‘Poulpal106’ has 137 flower petals, ‘Poulpal062’ has 50 flower petals. The claimed plant has a flower diameter of 60 mm while ‘Poulpal062’ has a flower diameter of 75 mm. Open flowers of ‘Poulpal106’ are generally Red Group 43C in colour, becoming Red Group 52C as the flower matures. The comparison variety, ‘Poulpal062’, has a general tonality of Red Group 40C becoming Red Group 43C as flowers mature.Flower and Flower Bud
