Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yobrandi’, 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; dark 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 Yobrandi.

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 ‘Yobrandi’.

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 coloration and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in November, 1999 in Salinas, Calif., of a proprietary Chrysanthemum×morifolium seedling selection identified as code number 93- L355001, not patented, as the female, or seed, parent with a proprietary Chrysanthemum×morifolium seedling selection 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, 2000. 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, 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 Yobrandi 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 unique characteristics of ‘Yobrandi’. These characteristics in combination distinguish ‘Yobrandi’ 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. Dark 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 Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the female parent, the proprietary seedling selection identified as code number 93-L355001, in the following characteristics:

- 1. Plants of the new Chrysanthemum had smaller inflorescences than plants of the female parent selection.
- 2. Plants of the new Chrysanthemum and the female parent selection differed in ray floret coloration as plants of the female parent selection had coral-colored ray florets.

In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the male parent, the proprietary seedling selection identified as code number 96-L011, in the following characteristics:

- 1. Plants of the new Chrysanthemum flowered more uniformly than plants of the male parent selection.
- 2. Plants of the new Chrysanthemum had darker red-colored ray florets than plants of the male parent selection.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Helen, disclosed in U.S. Plant Pat. No. 9,793. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Helen in the following characteristics:

- 1. Plants of the new Chrysanthemum were shorter, more mounded and stronger than plants of the cultivar Helen.
- 2. Plants of the new Chrysanthemum flowered about ten days later than plants of the cultivar Helen.
- 3. Ray florets of plants of the new Chrysanthemum resisted fading better than ray florets of plants of the cultivar Helen.

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

- 1. Plants of the new Chrysanthemum were more mounded and more outwardly spreading than plants of the cultivar Arezzo.
- 2. Ray florets of plants of the new Chrysanthemum were darker red in color and resisted fading better than ray florets of plants of the cultivar Arezzo.

These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yobrandi’ grown in a container.

The photograph on the second sheet comprises a close-up view of typical inflorescences of the cultivar ‘Yobrandi’.

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.
