Shrub rose plant named ‘Poultc014’

Abstract

A new garden rose plant of the shrub class which has abundant, yellow flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical classification: Rosa hybrida.

Variety denomination: ‘Poultc014’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling (non-patented), and the male pollen parent, an unnamed seedling (non-patented). The two parents were crossed during the summer of 1998, and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poultc014’.

The new variety may be distinguished from its seed parent, by the following combination of characteristics:

• • 1. The claimed plant is more compact in growth height than the seed parent.
  • 2. The claimed plant has flowers which are more deep yellow in color than those of the seed parent.

The new variety may be distinguished from the male pollen parent by the following combination of characteristics:

• • 1. The claimed plant has smaller flowers than the pollen parent.
  • 2. The claimed plant has more flowers per flowering stem than the pollen parent.

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

• • 1. Uniform and abundant deep yellow flowers;
  • 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
  • 3. Improved disease resistance; and
  • 4. Suitability for container nursery culture.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poultc014’ 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 1998 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poultc014’ was selected in the spring 1999 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poultc014’ by traditional budding and rooted cuttings was first done by and Mogens N. Olesen in Fredensborg, Denmark in July, 1999. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poultc014’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poultc014’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age, grown on Rosa multiflora understock. 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 ‘Poulgode’, a rose variety from the same inventor described and illustrated in U.S. Plant patent application Ser. No. 10/782,360, now abandoned, are compared to ‘Poultc014’ in Chart 1.
