Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yotabitha’, characterized by its upright, outwardly spreading and rounded plant habit; freely branching habit; freely flowering habit; decorative-type inflorescences with elongated oblong-shaped ray florets; red-colored ray florets; natural season flowering in late September in the Northern Hemisphere; and good garden performance.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yotabitha.

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 ‘Yotabitha’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Fareham, Hants, United Kingdom. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret coloration and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in March, 2001 in Fareham, Hants, United Kingdom of a proprietary Chrysanthemum×morifolium seedling selection identified as code number G114A 1, not patented, as the female, or seed, parent with a proprietary Chrysanthemum×morifolium seedling selection identified as code number G57A 1, 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 Fareham, Hants, United Kingdom in September, 2001. 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 Fareham, Hants, United Kingdom since December, 2001, 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 Yotabitha 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 ‘Yotabitha’. These characteristics in combination distinguish ‘Yotabitha’ as a new and distinct cultivar of Chrysanthemum:

• • 1. Upright, outwardly spreading and rounded plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Decorative-type inflorescences with elongated oblong-shaped ray florets.
  • 5. Red-colored ray florets.
  • 6. Natural season flowering in late September in the Northern Hemisphere.
  • 7. Good garden performance.

In side-by-side comparisons conducted in Fareham, Hants, United Kingdom, plants of the new Chrysanthemum differed from plants of the female parent, the proprietary seedling selection identified as code number G114A 1, in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more rounded than plants of the female parent selection.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences and fewer disc florets per inflorescence than plants of the female parent selection.

In side-by-side comparisons conducted in Fareham, Hants, United Kingdom, plants of the new Chrysanthemum differed from plants of the male parent, the proprietary seedling selection identified as code number G57A 1, in the following characteristics:

• • 1. Plants of the new Chrysanthemum were larger than plants of the male parent selection.
  • 2. Plants of the new Chrysanthemum and the male parent selection differed in ray floret coloration as plants of the male parent selection had pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Bravo, disclosed in U.S. Plant Pat. No. 6,888. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Bravo in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more rounded, fuller and more uniform in plant habit than plants of the cultivar Bravo.
  • 2. Plants of the new Chrysanthemum flowered about one week later than plants of the cultivar Bravo.
  • 3. Ray florets of plants of the new Chrysanthemum resisted fading better than ray florets of plants of the cultivar Bravo.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Jenny Wren, disclosed in U.S. Plant Pat. No. 10,213. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Jenny Wren in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more rounded than but not as outwardly spreading as plants of the cultivar Jenny Wren.
  • 2. Plants of the new Chrysanthemum had slightly smaller inflorescences than plants of the cultivar Jenny Wren.
  • 3. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Jenny Wren.
  • 4. Ray florets of plants of the new Chrysanthemum were darker red in color than ray florets of plants of the cultivar Jenny Wren.

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 late summer and fall in an outdoor nursery and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was planted in a 15.25-cm container in mid-July. During the production of the plants, plants were exposed to natural season photoperiodic conditions with day temperatures averaging 26° C. and night averaging 18° C. Measurements and numerical values represent averages for typical flowering plants.
