Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yoveracruz’, characterized by its uniform and outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering response and habit; typically grown as a spray-type; early flowering habit; daisy-type inflorescences with spoon or quill-shaped ray florets; golden bronze-colored ray florets and green-colored disc florets that develop slowly; and good postproduction longevity with plants maintaining good substance and color for about three to five weeks in an interior environment.

Description

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

BACKGROUND OF THE INVENTION

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

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Fort Myers, Fla. The objective of the program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in May, 1998, in Salinas, Calif., of the Chrysanthemum cultivar Spears, disclosed in U.S. Plant Pat. No. 5,620, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as code number YB-5897, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor in March, 1999, as a single flowering plant from within the resulting progeny of the stated cross-pollination grown in a controlled environment in Fort Myers, Fla.

The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in June, 1999. Asexual reproduction by cuttings 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 Yoveracruz has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

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

- 1. Uniform and outwardly spreading plant habit.
- 2. Strong and freely branching growth habit.
- 3. Dark green-colored foliage.
- 4. Uniform flowering response and habit.
- 5. Typically grown as a spray-type.
- 6. Early flowering, eight week response time.
- 7. Daisy-type inflorescences with spoon and quill-shaped ray florets.
- 8. Golden bronze-colored ray florets and green-colored disc florets that develop slowly.
- 9. Good postproduction longevity with plants maintaining good substance and color for about three to five weeks in an interior environment.

Plants of the new Chrysanthemum can be compared to plants of the female parent, the cultivar Spears. Plants of the new Chrysanthemum differ from plants of the cultivar Spears primarily in ray floret coloration as plants of the cultivar Spears have white-colored ray florets. In addition, plants of the new Chrysanthemum are more vigorous than plants of the cultivar Spears.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ from plants of the male parent selection primarily in ray floret coloration as plants of the male parent selection have red purple-colored ray florets. In addition, plants of the new Chrysanthemum flower about one week earlier than plants of the male parent selection.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Golden State, disclosed in U.S. Plant Pat. No. 8,694. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Golden State in the following characteristics:

- 1. Plants of the new Chrysanthemum were shorter than plants of the cultivar Golden State.
- 2. Plant habit of the new Chrysanthemum was more uniform than plant habit of the cultivar Golden State.
- 3. Plants of the new Chrysanthemum and the cultivar Golden State differed in inflorescence form as plants of the cultivar Golden State had anemone-type inflorescences.

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, following observations and measurements describe plants grown and flowered during the autumn in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, the following conditions were measured: day temperatures, 21 to 27° C.; night temperatures, 17 to 19° C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cm containers, exposed to long day/short night conditions, and pinched once about two weeks later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
