Chrysanthemum plant named ‘Fall’

Abstract

A distinct cultivar of Chrysanthemum plant named ‘Fall’, characterized by its upright plant habit; dark-green-colored foliage; freely flowering habit; decorative-type inflorescences that are about 7.4 cm in diameter; attractive orange bronze-colored ray florets; response time about 60 days; strong peduncles; and good postproduction longevity with inflorescences and foliage maintaining good substance and color for about two weeks in an interior environment.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Fall.

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 ‘Fall’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new cut Chrysanthemum cultivars having infloresences with desirable colors and good inflorescence form and substance.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in December, 1997, in Salinas, Calif., of a proprietary Chrysanthemum×morifolium seedling selection identified as code number E523, not patented, as the female, or seed, parent with a proprietary Chrysanthemum×morifolium seedling selection identified as D360, not patented, as the male, or pollen, parent.

The cultivar Fall was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., in November, 2000. The selection of this plant was based on its desirable inflorescence color and good inflorescence form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Alva, Fla. since February, 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 Fall 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 ‘Fall’. These characteristics in combination distinguish ‘Fall’ as a new and distinct cultivar:

• • 1. Upright cut Chrysanthemum that is usually grown as a natural spray.
  • 2. Dark green-colored foliage. dqzw
  • 3. Freely flowering habit, about seven inflorescences per flowering stem.
  • 4. Decorative-type inflorescences that are about 7.4 cm in diameter.
  • 5. Attractive orange bronze-colored ray florets.
  • 6. Response time about 60 days.
  • 7. Strong peduncles.
  • 8. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about two weeks in an interior environment.

Compared to plants of the female parent selection, plants of the new Chrysanthemum have slightly larger inflorescences and differ in ray floret coloration as plants of the female parent selection have yellow-colored ray florets.

Compared to plants of the male parent selection, plants of the new Chrysanthemum have larger inflorescences, fewer disc florets per inflorescence and differ in ray floret coloration as plants of the male parent selection have pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum×morifolium cultivar Win, disclosed in U.S. Plant Pat. No. 5,108. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Win in the following characteristics:

• • 1. Plants of the new Chrysanthemum had smaller leaves than plants of the cultivar Win.
  • 2. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Win.
  • 3. Plants of the new Chrysanthemum flowered about one week earlier than plants of the cultivar Win.
  • 4. Ray floret color of plants of the new Chrysanthemum was slightly darker orange bronze than ray floret color of plants of the cultivar Win.

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 Madrid, Cundinamarca, Colombia, South America, under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Sep. 1, 2003 and received 18 long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 18 to 24° C.; night temperatures, 4 to 12° C.; and light levels, 3,000 to 5,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about nine to ten weeks after the start of short days.
