Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘G19OTI06PI’, characterized by its upright, outwardly spreading and uniformly rounded plant habit; vigorous growth habit; freely branching habit; dense and full plant habit; dark green-colored leaves; uniform and freely flowering habit; long flowering period; and decorative-type inflorescences with light red purple-colored ray florets.

Description

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘G19OTI06PI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘G19OTI06PI’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in October, 2013 in Oostnieuwkerke, Belgium of Chrysanthemum X morifolium ‘Katelijn’, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum X morifolium identified as code number GE09 1917, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from which the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2014.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2016. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G19OTI06PI’. These characteristics in combination distinguish ‘G19OTI06PI’ as a new and distinct Chrysanthemum plant:

• • 1. Upright, outwardly spreading and uniformly rounded plant habit; vigorous growth habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Dark green-colored leaves.
  • 4. Uniform and freely flowering habit.
  • 5. Long flowering period.
  • 6. Decorative-type inflorescences with light red purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the female parent, ‘Katelijn’. Plants of the new Chrysanthemum differ primarily from plants of ‘Katelijn’ in the following characteristics:

• • 1. Plants of the new Chrysanthemum are more uniformly rounded than plants of ‘Katelijn’.
  • 2. Inflorescences of plants of the new Chrysanthemum are slightly smaller than inflorescences of plants of ‘Katelijn’.
  • 3. Ray florets of plants of the new Chrysanthemum are light red purple in color whereas ray florets of plants of ‘Katelijn’ are yellow in color.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Chrysanthemum are more vigorous than plants of the male parent selection.
  • 2. Plants of the new Chrysanthemum flower about five weeks earlier than plants of the male parent selection.
  • 3. Ray florets of plants of the new Chrysanthemum are lighter red purple in color than ray florets of plants of the male parent selection.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘Fiora Pink’, disclosed in U.S. Plant Pat. No. 26,462. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Fiora Pink’ in the following characteristics:

• • 1. Stems of plants of the new Chrysanthemum are more flexible than and not as rigid as stems of plants of ‘Fiora Pink’.
  • 2. Plants of the new Chrysanthemum flower about four weeks later than plants of ‘Fiora Pink’.
  • 3. Inflorescences of plants of the new Chrysanthemum are smaller than inflorescences of plants of ‘Fiora Pink’.
  • 4. Ray florets of plants of the new Chrysanthemum are light red purple in color whereas ray florets of plants of ‘Fiora Pink’ are greyed purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of a typical flowering plant of ‘G19OTI06PI’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and detailed description were taken.
