ABSTRACT:
SUMMARY OF THE INVENTION
The present discovery constitutes a new and distinct variety of a miniature rose plant which was discovered in a cultivated area in Fredensborg, Denmark. The mutation resulted from ‘POULgold’, a non-patented, miniature pot rose hybridized by the same inventors, with PBR Registration Number in Denmark, No. 2108, granted on Jan. 29, 1991. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘POULgold’.
The rose plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from the original rose ‘POULgold’ as well as all other varieties which we are aware of. For example, the new variety has:
1. Abundant, yellow colored flowers with red intonations on the margins;
2. Vigorous and compact growth,
3. Year-round flowering under glasshouse conditions;
4. Suitability for production from softwood cuttings in pots;
5. Durable flowers and foliage which make the variety suitable for distribution in the floral industry.
The combination of qualities of this variety represents significant improvement over previously available commercial cultivars of this type and distinguishes ‘POULrosit’ from all other varieties of which we are aware. As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen budded cuttings taken from the aforementioned mutation and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
Asexual reproduction of ‘POULrosit’ by cuttings and traditional budding onto
Rosa Multiflora
understock was first done by L. Pernille and Mogens N. Olesen in October of 1998 at their nursery in Fredensborg, Denmark. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULrosit’ are true to type and are transmitted from one generation to the next.
