ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as
Dendranthema grandiflora
and referred to by the cultivar name Eurobelle.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Hensbroek, The Netherlands. The objective of the program is to create and develop new Chrysanthemum cultivars with interesting inflorescence forms, attractive floret colors, and good post-production longevity.
The new Chrysanthemum originated from a cross by the Inventor of the Inventor's proprietary selection of
Dendranthema grandiflora
identified as K.O.5001.06 as the female, or seed, parent with the Inventor's proprietary selection of
Dendranthema grandiflora
identified as K.O.5001.31 as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Hensbroek, The Netherlands in 1996. The selection of the new Chrysanthemum was based on its inflorescence form and ray floret coloration.
Asexual reproduction of the new Chrysanthemum by terminal cuttings harvested in Hensbroek, The Netherlands, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The cultivar Eurobelle has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Eurobelle’. These characteristics in combination distinguish ‘Eurobelle’ as a new and distinct cultivar:
1. White decorative inflorescences with green centers.
2. Dark green foliage.
3. Early response time.
4. Good post-production longevity.
Plants of the new Chrysanthemum differ from plants of the female parent, the selection K.O.5001.06, primarily in ray floret color as the female parent has pink-colored ray florets. In addition, plants of the new Chrysanthemum are more vigorous than plants of the female parent. Plants of the new Chrysanthemum differ from plants of the male parent, the selection K.O.5001.31, primarily in inflorescence form as the male parent has semi-decorative inflorescences. In addition, inflorescences of plants of the new Chrysanthemum form very little pollen whereas inflorescences of plants of the male parent form abundant pollen.
Plants of the new Chrysanthemum can be compared to the Chrysanthemum cultivar Calabria, not patented. In side-by-side comparisons conducted by the Inventor in Hensbroek, The Netherlands, plants of the new Chrysanthemum and the cultivar Calabria differ in the following characteristics:
1. Plants of the new Chrysanthemum have longer flowering stems than plants of the cultivar Calabria.
2. Inflorescence centers of plants of the new Chrysanthemum are more green in color than inflorescence centers of plants of the cultivar Calabria.
3. Plants of the new Chrysanthemum have longer post-production longevity than plants of the cultivar Calabria.
