ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as
Dendranthema grandiflora
and hereinafter referred to by the cultivar name Yoreno.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. The objective of the breeding program is to create new pot-type Chrysanthemum cultivars having desirable inflorescence forms and floret colors and good post-production longevity.
The new Chrysanthemum originated from a cross made by the Inventor in October, 1994, in Salinas, Calif., of the
Dendranthema grandiflora
cultivar Rage, disclosed in U.S. Plant Pat. No. 8,770, as the female, or seed, parent, with the
Dendranthema grandiflora
cultivar Miramar, disclosed in U.S. Plant Pat. No. 7,469, as the male, or pollen, parent.
The new Chrysanthemum was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in November, 1995. The selection of this plant was based on its desirable inflorescence form and floret colors and good post-production longevity.
Asexual reproduction of the new Chrysanthemum by terminal cuttings harvested in a controlled environment in Alva, Fla., 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 Yoreno 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 ‘Yoreno’. These characteristics in combination distinguish ‘Yoreno’ as a new and distinct Chrysanthemum:
1. Upright, outwardly spreading and uniformly mounded plant habit.
2. Vigorous and strong growth habit.
3. Freely branching habit, full and dense plants.
4. Strong, dark green foliage.
5. Uniform flowering.
6. Nine-week response time.
7. Freely flowering; numerous large daisy-type inflorescences that are about 7.5 cm in diameter.
8. Dark orange-colored ray florets that resist fading; ray florets held upright.
9. Large disc with green disc florets that are slow to mature to bright yellow.
10. Good postproduction longevity with inflorescences and leaves maintaining good substance and color for about two to three weeks in an interior environment.
11. Excellent year-round production performance.
The new Chrysanthemum can be compared to the Chrysanthemum cultivar Orange Davis, disclosed in U.S. Plant Pat. No. 8,295. However in side-by-side comparisons in Salinas, Calif., and Leamington, Ontario, Canada, under commercial practice, plants of the new Chrysanthemum differ from plants of the cultivar Orange Davis in the following characteristics:
1. Plants of the new Chrysanthemum are stronger than plants of the cultivar Orange Davis.
2. Plants of the new Chrysanthemum are typically not as outwardly spreading as plants of the cultivar Orange Davis.
3. Plants of the new Chrysanthemum are more freely branching, fuller and denser than plants of the cultivar Orange Davis.
4. Plants of the new Chrysanthemum have shorter leaves than plants of the culltivar Orange Davis.
5. Inflorescences of plants of the new Chrysanthemum are larger and have more ray florets than inflorescences of plants of the cultivar Orange Davis.
6. Inflorescences of plants of the new Chrysanthemum have darker orange, longer, and narrower ray florets than inflorescences of plants of the cultivar Orange Davis.
7. Spray formation of plants of the new Chrysanthemum is not as clubby as spray formation of plants of the cultivar Orange Davis.
8. Plants of the new Chrysanthemum have much better winter production performance than plants of the cultivar Orange Davis.
