Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Zembla Sunny’, characterized by its decorative-type inflorescences with dark yellow-colored ray florets; freely flowering habit; early and uniform flowering response; and good postproduction longevity.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Zembla Sunny.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and referred to by the name ‘Zembla Sunny’.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum cultivar Zembla, disclosed in U.S. Plant Pat. No. 14,052. The new Chrysanthemum was discovered and selected by the Inventor on Jun. 18, 2002 within a population of flowering plants of the cultivar Zembla in a controlled environment in 's Gravenzande, The Netherlands.
Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in 's Gravenzande, The Netherlands since Jul. 18, 2002, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The cultivar Zembla Sunny 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 ‘Zembla Sunny’. These characteristics in combination distinguish ‘Zembla Sunny’ as a new and distinct cultivar:
    • 1. Decorative-type inforescences with dark yellow-colored ray florets; typically grown as a spray-type.
    • 2. Freely flowering habit.
    • 3. Early and uniform flowering response.
    • 4. Good postproduction longevity.
Plants of the new Chrysanthemum can be compared to plants of the parent, the cultivar Zembla. In side-by-side comparisons conducted in 's Gravenzande, The Netherlands, plants of the new Chrysanthemum differed from plants of the cultivar Zembla in the following characteristics:
    • 1. Plants of the new Chrysanthemum were not as vigorous as plants of the cultivar Zembla.
    • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Zembla.
    • 3. Plants of the new Chrysanthemum and the cultivar Zembla differed in ray floret coloration as plants of the cultivar Zembla had white-colored ray florets.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Zembla Yellow, disclosed in U.S. Plant Pat. No. 14,733. In side-by-side comparisons conducted in 's Gravenzande, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Zembla Yellow in the following characteristics:
    • 1. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Zembla Yellow.
    • 2. Plants of the new Chrysanthemum and the cultivar Zembla Yellow differed in ray floret coloration as plants of the cultivar Zembla Yellow had lighter yellow-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing 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 actual color of the new Chrysanthemum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of ‘Zembla Sunny’.
The photograph at the bottom left of the sheet is a close-up view of upper surface of a typical inflorescence and a typical leaf of ‘Zembla Sunny’.
The photograph at the bottom right of the sheet is a close-up view of lower surface of a typical inflorescence and a typical leaf of ‘Zembla Sunny’.
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 aforementioned photographs and following observations and measurements describe plants grown during the winter and early spring in 's Gravenzande, The Netherlands, under commerical practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During production of the plants, day and night temperatures averaged 19° C. and light levels were about 4,000 lux. Plants were grown as spray-types and were about ten weeks from planting when the photographs and the description were taken.
  • Botanical classification: Chrysanthemum×morifolium cultivar Zembla Sunny.
  • Commercial classification: Decorative-type Chrysanthemum typically grown as a spray-type cut flower.
  • Parentage: Naturally-occurring whole plant mutation of Chrysanthemum×morifolium cultivar Zembla, disclosed in U.S. Plant Pat. No. 14,052.
  • Propagation:
