USPP20210P2 - Chrysanthemum plant named ‘Yowanda’ - Google Patents

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yowanda’, characterized by its upright, outwardly spreading and mounding plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; decorative-type inflorescences with lavender-colored ray florets; and natural season flowering about October 3^rd in the Northern Hemisphere.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘YOWANDA’.

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 perennial garden Chrysanthemum,

The objective of the breeding program is to create new perennial garden-type Chrysanthemum cultivars having uniformly rounded plant habit, inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in February, 2003, in Salinas, Calif. of Chrysanthemum×morifolium ‘Yotabitha’, disclosed in U.S. Plant Pat. No. 16,110, as the female, or seed, parent with Chrysanthemum×morifolium ‘Yoursula’, disclosed in U.S. Plant Pat. No. 13,641, 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 greenhouse environment in Alva, Fla. in November, 2003.

Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in a controlled greenhouse environment in Alva, Fla. in January, 2004. Asexual reproduction by cuttings 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 new Chrysanthemum 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 ‘Yowanda’. These characteristics in combination distinguish ‘Yowanda’ as a new and distinct garden Chrysanthemum cultivar:

• • 1. Upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Uniform and freely flowering habit.
  • 4. Decorative-type inflorescences.
  • 5. Lavender-colored ray florets.
  • 6. Natural season flowering occurs about October 3^rd 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, ‘Yotabitha’, in the following characteristics:

• • 1. Plants of the new Chrysanthemum were not as spherical as plants of ‘Yotabitha’.
  • 2. Plants of the new Chrysanthemum flowered three days later than plants of ‘Yotabitha’ when grown under natural season conditions.
  • 3. Plants of the new Chrysanthemum and ‘Yotabitha’ differed in ray floret color as plants of ‘Yotabitha’ had red-colored ray florets.

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

• • 1. Plants of the new Chrysanthemum were larger than plants of ‘Yoursula’.
  • 2. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Yoursula’.
  • 3. Plants of the new Chrysanthemum flowered two weeks later than plants of ‘Yoursula’ when grown under natural season conditions.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Bold Yomelissa’, disclosed in U.S. Plant Pat. No. 14,735. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of ‘Bold Yomelissa’ in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more rounded than and not as upright as plants of ‘Bold Yomelissa’.
  • 2. Plants of the new Chrysanthemum were stronger than plants of ‘Bold Yomelissa’.
  • 3. Plants of the new Chrysanthemum had slightly smaller inflorescences than plants of ‘Bold Yomelissa’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Amor Dark Pink’, disclosed in U.S. Plant Pat. No. 14,592. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of ‘Amor Dark Pink’ in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more rounded than and not as upright as plants of ‘Amor Dark Pink’.
  • 2. Plants of the new Chrysanthemum were stronger than plants of ‘Amor Dark Pink’.
  • 3. Plants of the new Chrysanthemum flowered more uniformly than plants of ‘Amor Dark Pink’.
  • 4. Plants of the new Chrysanthemum flowered five days earlier than plants of ‘Amor Dark Pink’ when grown under natural season conditions.
  • 5. Plants of the new Chrysanthemum had slightly smaller inflorescences than plants of ‘Amor Dark Pink’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Yowanda’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Alva, Fla. during the late spring and summer in a polycarbonate-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden Chrysanthemum production. During the production of the plants, day temperatures averaged 32° C. and night temperatures averaged 21° C. Plants were grown in 15-containers under short day/long night conditions. Plants were ten weeks from planting when the photographs and description were taken. 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.
