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 Empire Blizzard.
The new cultivar is a product of a planned breeding program conducted by the Inventor in New Hartford, N.Y. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.
The new cultivar originated form a cross made by the Inventor in October, 1994, of the
Dendranthema grandiflora
cultivar Empire Aspen U.S. Plant Pat. No. 7,885 as the male, or pollen, parent with an unidentified proprietary seedling selection as the female, or seed, parent.
The cultivar Empire Blizzard was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in New Hartford in September, 1995. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and excellent garden performance. Plant of new Chrysanthemum have larger inflorescences, fewer ray florets and flower more uniformly than plants of the parent cultivar, Empire Aspen.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in New Hartford has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Empire Blizzard 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 repreatedly observed and are determined to be the unique characteristics of ‘Empire Blizzard’. These characteristics in combination distinguish ‘Empire Blizzard’ as a new and distinct cultivar:
1. Uniformly mounded plant habit.
2. Freely branching and large leaves; dense, full plants.
3. Uniform flowering.
4. Large flat daisy-type inflorescences that are about 6.4 cm in diameter.
5. Attractive long white ray florets that do not “pink” under low temperatures.
6. Bright yellow disc florets that develop slowly and maintain immature green coloration.
7. Numerous inflorescences per plant.
8. Excellent garden performance.
The new Chrysanthemum is similar to the Chrysanthemum cultivar Tracy, disclosed in U.S. Plant Pat. No. 8,609. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differ from plants of the cultivar Tracy in the following characteristics:
1. Plants of the new Chrysanthemum are denser and have larger leaves than plants of the cultivar Tracy.
2. Plants of the new Chrysanthemum flower about 10 to 14 days later than plants of the cultivar Tracy under natural season conditions.
3. Plants of the new Chrysanthemum have larger inflorescences than plants of the cultivar Tracy.
4. Plants of the new Chrysanthemum have a more distinct daisy inflorescence form with fewer but longer ray florets than plants of the cultivar Tracy.
5. Plants of the new Chrysanthemum maintain green centers longer than plants of the cultivar Tracy.
6. Plants of the new Chrysanthemum flower more uniformly than plants of the cultivar Tracy.
7. Ray florets of plants of the cultivar Tracy tend to “pink” under low temperatures, whereas ray floret color of plants of the new Chrysanthemum maintain white color under low temperatures.
