ABSTRACT:
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between ‘Margaret Merril’ and unnamed seedling. The two parents were crossed and the resultng seeds were planted in a controlled environment. The new variety is named ‘POULdra’.
The new rose may be distinguished from its seed parent, ‘Margaret Merril’, by the following combination of characteristics:
1. The seed parent has pure white flowers and ‘POULdra’ has deep pink flowers;
2. The seed parent has a larger flower size;
3. The seed parent has a higher number of flower petals when compared to ‘POULdra’.
The new variety may be distinguished from its pollen parent, an unnamed seedling created by the same inventors, by the following combination of characteristics:
1. The pollen parent has no fragrance while ‘POULdra’ is exceptionally fragrant;
2. The pollen parent dose not grow as tall as ‘POULdra’;
3. The pollen parent has more petals (very double) while ‘POULdra’ flowers are double.
The objective of the hybridization of this rose variety for nursery and garden use was to create a new and distinct variety with unique qualities, such as:
1. Uniform and abundant flowers;
2. Vigorous, compact growth;
3. Exceptional fragrance;
4. Disease Resistance.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULdra’ 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 and conducted elaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULdra’ was selected in the summer of 1988 by the inventors as a single plant from the aforementioned hybridization.
Asexual reproduction of ‘POULdra’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August 1989, at their nursery in Fredensborg, Denmark. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULdra’ are true to type and are transmitted from one generation to the next.
