Chrysanthemum plant named ‘Yofiona’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yofiona’, characterized by its compact, upright and somewhat outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; medium decorative-type inflorescences with elongated oblong-shaped ray florets; coral bronze-colored ray florets; and natural season flowering in mid-September in the Northern Hemisphere.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yofiona’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yofiona’.

The new cultivar 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 garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in December, 1999 in Salinas, Calif., of the Chrysanthemum×morifolium cultivar Yogretchen, disclosed in U.S. Plant Pat. No. 13,672, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 96-L011, 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 grown in a controlled environment in Alva, Fla. in October, 2002. The selection of this plant was based on its desirable inflorescence form, attractive floret coloration and good garden performance.

Asexual reproduction of the new cultivar by terminal vegetative cuttings in a controlled environment in Alva, Fla. since January, 2003, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yofiona has 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 ‘Yofiana’. These characteristics in combination distinguish ‘Yofiona’ as a new and distinct cultivar:

• • 1. Upright and somewhat outwardly spreading plant habit.
  • 2. Freely branching habit; dense and full plants.
  • 3. Uniform and freely flowering habit.
  • 4. Medium decorative-type inflorescences with elongated oblong-shaped ray florets.
  • 5. Coral bronze-colored ray florets.
  • 6. Natural season flowering in mid-September in the Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the female parent, the cultivar Yogretchen, primarily in ray floret coloration as plants of the cultivar Yogretchen had orange-colored ray florets.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Chrysanthemum were fuller and more mounded than plants of the male parent selection.
  • 2. Plants of the new Chrysanthemum flowered more uniformly than plants of the male parent selection.
  • 3. Plants of the new Chrysanthemum had smaller inflorescences than plants of the male parent selection.
  • 4. Ray florets of plants of the new Chrysanthemum were more bronze/less purple in color than ray florets of plants of the male parent selection.
  • 5. Plants of the new Chrysanthemum had fewer disc florets per inflorescence than plants of the male parent selection.
  • 6. Plants of the new Chrysanthemum flowered about six days earlier than plants of the male parent selection when grown under natural season conditions.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Dark Grenadine, disclosed in U.S. Plant Pat. No. 7,632. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Dark Grenadine in the following characteristics:

• • 1. Plants of the new Chrysanthemum were smaller and more mounded than plants of the cultivar Dark Grenadine.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Dark Grenadine.
  • 3. Plants of the new Chrysanthemum were not susceptible to heat delay whereas plants of the cultivar Dark Grenadine were susceptible to heat delay.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Tuscany, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Tuscany in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more mounded than and not as rounded as plants of the cultivar Tuscany.
  • 2. Plants of the Chrysanthemum had better garden performance and were durable than plants of the cultivar Tuscany.
  • 3. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Tuscany.
  • 4. Ray florets of plants of the new Chrysanthemum were more bronze/less pinkish coral in color than ray florets of plants of the cultivar Tuscany.
  • 5. Ray florets of plants of the new Chrysanthemum had much better color retention than ray florets of plants of the cultivar Tuscany.
  • 6. Plants of the new Chrysanthemum were not affected by heat delay whereas plants of the cultivar Tuscany were extremely affected by heat delay.

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 following observations and measurements describe plants grown in Leamington, Ontario, Canada during the summer in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. Rooted cuttings were planted in 15.25-cm containers, grown under artificial long day conditions (four-hour night interruption) and pinched about ten days later. About ten days after the pinch, plants were then exposed to artificial short day conditions (11.5 hours light) until flowering. During the production of the plants, temperatures ranged from 18° C. to 38° C. Measurements and numerical values represent averages for typical flowering plants.
