STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR AND APPLICANT/ASSIGNEEAn European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Pieters Joseph & Luc B. V. of Staden-Oostnieuwkerke, Belgium on Jan. 17, 2022, application number 2022/0148. Foreign priority is not claimed to this European Community Plant Breeder's Rights application.
The Inventor and Applicant/Assignee assert that no sales, offers for sale or public distribution of the instant plant occurred more than one year prior to the effective filing date of this application.
Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosures and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘Josarador’.
The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Staden-Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.
The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum X morifolium ‘Josarama’, disclosed in U.S. Plant patent application Ser. No. 18/527,274 filed concurrently. ‘Josarama’ was originally referred to as ‘Josarma’ in the provisional U.S. Patent Application 63/430.011. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Josarama’ in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in October 2017.
Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in February 2018. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Josarador’. These characteristics in combination distinguish ‘Josarador’ as a new and distinct Chrysanthemum plant:
-
- 1. Relatively compact, upright, outwardly spreading and uniformly rounded plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit; dense and full plant habit.
- 4. Medium green-colored leaves.
- 5. Early, uniform and freely flowering habit.
- 6. Decorative type inflorescences with ray florets that are reddish orange in color.
- 7. Relative resistance to Fusarium Wilt, White Rust and Verticillium Wilt.
- 8. Good greenhouse and outdoor performance.
Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘Josarama’. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Josarama’ in ray floret color as ray florets of plants of the new Chrysanthemum are reddish orange in color whereas ray florets of plants of ‘Josarama’ are dark purplish red in color.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘JO44ORA’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘JO44ORA’ in the following characteristics:
-
- 1. Plants of the new Chrysanthemum are more compact than plants of ‘JO44ORA’.
- 2. Inflorescences of plants of the new Chrysanthemum have more ray florets and are denser than inflorescences of ‘JO44ORA’.
- 3. Ray florets of plants of the new Chrysanthemum are darker reddish orange in color than ray florets of plants of ‘JO44ORA’.
The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The aforementioned photographs and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Staden-Oostnieuwkerke, Belgium under natural daylengths during the autumn and employing cultural practices typically used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 10 C to 25 C and night temperatures ranged from 5 C to 15 C. Plants were 3.5 months old when the photographs and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
