Chrysanthemum plant named ‘Yosaloon’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yosaloon’, characterized by its upright plant habit; dark green-colored foliage; freely and uniformly flowering habit; decorative-type inflorescences; attractive two-tone orange bronze-colored ray florets; response time about 63 days; strong peduncles; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yosaloon’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a cut flower and hereinafter referred to by the name ‘Yosaloon’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Bogota, Colombia. The objective of the program is to create and develop new cut Chrysanthemum cultivars having inflorescences with desirable floret coloration and good inflorescence form and substance.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in January, 2001, in Salinas, Calif. of a proprietary selection of Chrysanthemum×morifolium identified as code number T3502, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number R326, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bogota, Colombia in June, 2002. The selection of this plant was based on its desirable ray floret color and good inflorescence form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Bogota, Colombia since August, 2002, 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 Yosaloon 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 ‘Yosaloon’. These characteristics in combination distinguish ‘Yosaloon’ as a new and distinct cultivar of Chrysanthemum:

• • 1. Upright plant habit.
  • 2. Dark green-colored foliage.
  • 3. Freely and uniformly flowering habit.
  • 4. Decorative-type inflorescences that are about 7 cm in diameter.
  • 5. Attractive two-tone orange bronze-colored ray florets.
  • 6. Response time about 63 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.

Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Chrysanthemum are taller than plants of the female parent selection.
  • 2. Plants of the new Chrysanthemum are more freely flowering than plants of the female parent selection.
  • 3. Plants of the new Chrysanthemum have longer peduncles than plants of the female parent selection.
  • 4. Plants of the new Chrysanthemum and the female parent selection differ in ray floret color as plants of the female parent selection have light pink-colored ray florets.

Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Chrysanthemum are more uniformly flowering than plants of the male parent selection.
  • 2. Plants of the new Chrysanthemum flower earlier than plants of the male parent selection.
  • 3. Plants of the new Chrysanthemum and the male parent selection differ in ray floret coloration as plants of the male parent selection have bright red-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Madera, disclosed in U.S. Plant Pat. No. 9,690. In side-by-side comparisons conducted in Bogota, Colombia, plants of the new Chrysanthemum differed from plants of the cultivar Madera in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered much earlier and more uniformly than plants of the cultivar Madera.
  • 2. Plants of the new Chrysanthemum had darker colored ray florets than plants of the cultivar Madera.

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 Bogota, Colombia during the summer in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial Chrysanthemum production. During the production of the cut flowers, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 4° C. to 9° C. and light levels ranged from 3,000 to 4,000 footcandles. Measurements and numerical values represent averages for typical flowering plants. The photographs and measurements were taken when plants were about two months old from planting.
