A distinct cultivar of Chrysanthemum plant named ‘Yoduluth’, characterized by its upright, somewhat outwardly spreading and uniformly mounded plant habit; large vigorous plants; freely branching habit, full and dense plants; strong, dark green foliage; uniform flowering; nine-week response time; numerous large daisy-type inflorescences that are about 8.8 cm in diameter; dark purple and light pink-colored spoon-shaped ray florets with bright yellow-colored disc florets; and good postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.
Latest Yoder Brothers, Inc. Patents:
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically know as Dendranthema grandifora and hereinafter referred to by the cultivar name Yoduluth.
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 grandifora cultivar Rage, disclosed in U.S. Plant Pat. No. 8,770, as the female, or seed, parent, with the Dendranthema grandiflora cultivar Tijuana, disclosed in U.S. Plant Pat. No. 9,083, 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 April, 1996. 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 INVENTIONThe cultivar Yoduluth 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 ‘Yoduluth’. These characteristics in combination distinguish ‘Yoduluth’ as a new and distinct Chrysanthemum:
1. Upright, somewhat outwardly spreading and uniformly mounded plant habit.
2. Large vigorous plants.
3. Freely branching habit, full and dense plants.
4. Strong, dark green foliage.
5. Uniform flowering.
6. Nine-week response time.
7. Floriferous, numerous large daisy-type inflorescences that are about 8.8 cm in diameter.
8. Dark purple and light pink-colored spoon-shaped ray florets with bright yellow-colored disc florets.
9. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for at least three weeks in an interior environment.
The new Chrysanthemum can be compared to the Chrysanthemum cultivar Rapture, disclosed in U.S. Plant Pat. No. 8,179. However in side-by-side comparsions in Salinas, Calif., and Leamington, Ontario, Canada, under commerical practice, plants of the new Chrysanthemum differ from plants of the cultivar Rapture in the following characteristics:
1. Plants of the new Chrysanthemum are more vigorous, taller and stronger than plants of the cultivar Rapture.
2. Plants of the new Chrysanthemum are more upright and less spreading than plants of the cultivar Rapture.
3. Plants of the new Chrysanthemum flower about four or five days later than plants of the cultivar Rapture.
4. Ray florets of the new Chrysanthemum are darker purple in color than ray florets of the cultivar Rapture.
BRIEF DESCRIPTION OF THE PHOTOGRAPHSThe accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph on the first sheet comprises a top perspective view of a typical flowering plant of ‘Yodulth’.
The photograph on the second sheet comprises a close-up view of a typical inflorescence and upper (left) and lower (right) surfaces of typical leaves of the cultivar Yoduluth. Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTIONIn the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Salinas, Calif., and Leamington, Ontario, Canada, under greenhouse conditions which approximate those generally used in commerical potted Chrysanthemum production. Four unrooted cuttings were directly stuck in a 15-cm container and pinched once. Plants used for this description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
