Chrysanthemum plant named ‘Yellow Passadena Jogger’

Abstract

A new and distinct cultivar of chrysanthemum plant named ‘Yellow Passadena Jogger’, characterized by its uniform, upright, outwardly spreading and rounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; freely flowering habit; decorative-type inflorescences with bright yellow-colored ray florets; long flowering period; and excellent garden performance.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘YELLOW PASSADENA JOGGER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Yellow Passadena Jogger’.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘Passadena Jogger’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘Passadena Jogger’ in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in October, 2008.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in March, 2009. Asexual reproduction by 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 INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions and cultural 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 ‘Yellow Passadena Jogger’. These characteristics in combination distinguish ‘Yellow Passadena Jogger’ as a new and distinct Chrysanthemum plant:

• • 1. Uniform, upright, outwardly spreading and rounded plant habit; moderately vigorous growth habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Freely flowering habit.
  • 4. Decorative-type inflorescences with bright yellow-colored ray florets.
  • 5. Long flowering period.
  • 6. Excellent garden performance.

Plants of the new Chrysanthemum differ primarily from the mutation parent, ‘Passadena Jogger’, in ray floret color as plants of ‘Passadena Jogger’ have greyed yellow-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Tardel’, not patented. In side-by-side comparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Tardel’ in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered earlier than plants of ‘Tardel’.
  • 2. Plants of the new Chrysanthemum had decorative type inflorescences whereas plants of ‘Tardel’ had diays type inflorescences.
  • 3. Plants of the new Chrysanthemum were not susceptible to Rust pathogens whereas plants of ‘Tardel’ were susceptible to Rust pathogens.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant. The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yellow Passadena Jogger’ grown in a container. The photograph on the second sheet are close-up views of the upper and lower surfaces of typical inflorescences (left) of ‘Yellow Passadena Jogger’ and upper and lower surfaces of typical leaves (right) of ‘Yellow Passadena Jogger’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in 19-cm containers in an outdoor nursery in Staden-Oostnieuwkerke, Belgium and under conditions and practices which approximate those generally 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 5.5 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
