ABSTRACT:
CLASSIFICATION
Botanical:
Rosa hybrida
‘POULattra’.
Commercial: Shrub rose.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of shrub rose which originated from a controlled crossing between ‘Kormixal Suffolk’ and ‘an unnamed seedling’, both unpatented varieties. The two parents were crossed during the summer of 1993 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULattra’.
The new rose may be distinguished from its seed parent, ‘Kormixal Suffolk’, by the following combination of characteristics:
1. ‘POULattra’ exhibits dark red blooms, whereas ‘Kormixal Suffolk’ exhibits lighter red blooms with a yellow center.
2. ‘POULattra’ has small double blooms, whereas the seed parent has semi-double blooms.
The new variety may be distinguished from its pollen parent, ‘an unnamed seedling’ by the following combination of characteristics:
1. ‘POULattra’ is a shrub rose with a spreading, bushy habit, whereas the pollen parent is a miniature rose.
2. ‘POULattra’ has larger leaves and more foliage 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 dark red flowers;
2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
3. Disease resistance.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULattra’ from all other varieties of which we are aware.
As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter 1993 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULattra’ was selected in the spring 1994 by the inventors as a single plant from the progeny of the aforementioned hybridization. Asexual reproduction of ‘POULattra’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in summer 1994. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULattra’ are true to type and are transmitted from one generation to the next.
