Chrysanthemum plant named ‘Yellow Watch’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yellow Watch’, characterized by its upright cut Chrysanthemum that is usually grown as a disbud-type; dark green-colored foliage; decorative-type inflorescences; quill to spoon-shaped and bright yellow-colored ray florets; response time about 9.5 weeks; strong flowering stems; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yellow Watch’.

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 Watch’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Watch, disclosed in U.S. Plant Pat. No. 13,463. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of plants of the cultivar Watch in a controlled environment in Alva, Fla. in November, 2000. The selection of this plant was based on its unique and attractive ray floret coloration.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Alva, Fla. since January, 2001, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yellow Watch have 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 ‘Yellow Watch’. These characteristics in combination distinguish ‘Yellow Watch’ as a new and distinct cultivar:

• • 1. Upright cut Chrysanthemum that is usually grown as a disbud-type.
  • 2. Dark green-colored foliage.
  • 3. Large decorative-type inflorescences that are about 10.1 cm in diameter.
  • 4. Attractive quill or spoon-shaped and bright yellow-colored ray florets.
  • 5. Response time about 9.5 weeks.
  • 6. Strong flowering stems.
  • 7. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about three weeks in an interior environment.

Compared to plants of the parent, the cultivar Watch, plants of the new Chrysanthemum differ primarily in ray floret coloration as plants of the cultivar Watch have inflorescences with reddish brown centers which is enhanced by low production temperatures.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum×morifolium cultivar Treat, disclosed in U.S. Plant Pat. No. 14,788. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Treat in the following characteristics:

• • 1. Plants of the new Chrysanthemum had shorter but stronger flowering stems than plants of the cultivar Treat.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Treat.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The 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. 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.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Yellow Watch’ grown as a disbud-type.

The photograph on the second sheet comprises a close-up view of a typical inflorescence of ‘Yellow Watch’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Salinas, Calif., under conditions which approximate commercial practice in a polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Nov. 3, 2004 and received four weeks of long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem disbud-type cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 24 to 27° C.; night temperatures, 10 to 16° C.; and light levels, 2,000 to 4,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about ten weeks after the start of short days.
