USPP36838P3 - Floribunda rose plant named ‘Poulnap008’ - Google Patents

Abstract

A new garden rose plant of the floribunda class which has abundant, pink and apricot blend flowers with strong fragrance and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical designation: Rosa hybrida.

Variety denomination: ‘Poulnap008’.

This application claims priority to Plant Breeder's Rights Application Number 2023/1974, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 22, 2023, 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 ‘Poulnap008’, 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 larger flowers in less abundance than the claimed plant. The female seed parent plant has red flowers while the new variety has flowers with a pink and apricot color blend.

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

• • 1. Uniform and abundant pink and apricot blend flowers with perfume;
  • 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 ‘Poulnap008’ 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. ‘Poulnap008’ was selected in the spring of 2014 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulnap008’ 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 ‘Poulnap008’ 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 ‘Poulnap008’.

Specifically illustrated in FIG. 1 of the drawings are open flowers at various stages of development viewed from above, a flower bud and one quarter opened flower viewed from the side, a fully open flower viewed from the side, and flower petals detached revealing reproductive flower parts.

Specifically illustrated in FIG. 2 of the drawings is a cluster of flower buds on the branch, juvenile growth, a bare stem exhibiting prickles, and a mature compound leaf. Plants shown are 15 months old.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulnap008’, as observed in its growth in an outdoor nursery in Odense Denmark. Observed plants are 15 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.

For a comparison, several physical characteristics of the rose variety ‘Poulren036’, U.S. Plant Pat. No. 35,515 are compared to the claimed plant. While ‘Poulnap008’ has, in quantity, about 83 petals, ‘Poulren036’ has about 107 flower petals. The color of flower petal inner surface upon opening for that of ‘Poulnap008’ is described as Yellow Group 12C at the basal zone, middle and marginal zones are Red Group 38B with light shades of Yellow-Orange Group 19C throughout. The inner surface of flower petals upon opening for the comparison variety is Orange-Red Group 32C with a basal zone color Yellow-Orange Group 14B, with a basal zone of Yellow 11 A.
