Chrysanthemum plant named ‘Yomiranda’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yomiranda’, characterized by its upright, somewhat outwardly spreading and mounded 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; orange bronze-colored ray florets; and natural season flowering in mid to late September in the Northern Hemisphere.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yomiranda’.

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 ‘Yomiranda’.

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, 2001, in Salinas, Fla. of the Chrysanthemum×morifolium cultivar Yomelissa, disclosed in U.S. Plant Pat. No. 12,223, as the female, or seed, parent with the Chrysanthemum×morifolium cultivar Yogretchen, disclosed in U.S. Plant Pat. No. 13,672, 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 November, 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 Yomiranda 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 ‘Yomiranda’. These characteristics in combination distinguish ‘Yomiranda’ as a new and distinct cultivar:

• • 1. Upright, outwardly spreading and mounded 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. Orange bronze-colored ray florets.
  • 6. Natural season flowering in mid to late 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 Yomelissa, in the following characteristics:

• • 1. Plants of the new Chrysanthemum were slightly smaller and more mounded than plants of the cultivar Yomelissa.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Yomelissa.
  • 3. Plants of the new Chrysanthemum and the cultivar Yomelissa differed in ray floret coloration as plants of the cultivar Yomelissa had lavender-colored ray florets.
  • 4. Plants of the new Chrysanthemum flowered about five days earlier than plants of the cultivar Yomelissa when grown under natural season conditions.

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

• • 1. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Yogretchen.
  • 2. Developing ray florets of plants of the new Chrysanthemum were darker in color than developing ray florets of plants of the cultivar Yogretchen.
  • 3. Plants of the new Chrysanthemum had slightly larger inflorescences than plants of the cultivar Yogretchen.
  • 4. Plants of the new Chrysanthemum flowered about ten days later than plants of the cultivar Yogretchen when grown under natural season conditions.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yovicki, disclosed in U.S. Plant Pat. No. 12,239. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yovicki in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more mounded and less upright than plants of the cultivar Yovicki.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Yovicki.
  • 3. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Yovicki.

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

• • 1. Plants of the new Chrysanthemum were shorter than plants of the cultivar Orange Padre.
  • 2. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Orange Padre.
  • 3. Plants of the new Chrysanthemum had brighter orange-colored ray florets than plants of the cultivar Orange Padre.
  • 4. Ray floret color of plants of the new Chrysanthemum was longer lasting than ray floret color of plants of the cultivar Orange Padre.

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.
