Chrysanthemum plant named ‘Sunny Yotasha’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Sunny Yotasha’, characterized by its upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full appearance; uniform and freely flowering habit; small daisy-type inflorescences with elongated oblong-shaped ray florets; rich yellow-colored ray florets and darker yellow-colored disc florets; natural season flowering in mid-October in the Northern Hemisphere; and good garden performance.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Sunny Yotasha.

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 ‘Sunny Yotasha’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Yotasha, disclosed in a U.S. Plant patent application Ser. No. 10/937,759. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of plants of the cultivar Yotasha in a controlled environment in Alva, Fla. in April, 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 June, 2002, 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 Sunny Yotasha 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 ‘Sunny Yotasha’. These characteristics in combination distinguish ‘Sunny Yotasha’ as a new and distinct cultivar of Chrysanthemum:

• • 1. Upright, outwardly spreading and rounded plant habit.
  • 2. Freely branching habit; dense and full plants.
  • 3. Uniform and freely flowering habit.
  • 4. Small daisy-type inflorescences with elongated oblong-shaped ray florets.
  • 5. Rich yellow-colored ray florets and darker yellow-colored disc florets.
  • 6. Natural season flowering in mid-October 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 parent, the cultivar Yotasha, in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered about two or three days earlier than plants of the cultivar Yotasha.
  • 2. Plants of the new Chrysanthemum and the cultivar Yotasha differed in ray floret coloration as plants of the cultivar Yotasha had bronze-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Julia, disclosed in U.S. Plant Pat. No. 9,020. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Julia in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more compact and more rounded than plants of the cultivar Julia.
  • 2. Inflorescences of plants of the new Chrysanthemum had fewer ray florets than inflorescences of plants of the cultivar Julia.
  • 3. Plants of the new Chrysanthemum flowered about ten days later than plants of the cultivar Julia.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Gedi One Ylsap, disclosed in U.S. Plant Pat. No. 13,795. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Gedi One Ylsap in the following characteristics:

• • 1. Inflorescences of plants of the new Chrysanthemum had fewer ray florets than inflorescences of plants of the cultivar Gedi One Ylsap.
  • 2. Plants of the new Chrysanthemum flowered about two weeks earlier than plants of the cultivar Gedi One Ylsap.

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.
