Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Serginho’, characterized by its upright, outwardly spreading and mounded plant habit; freely branching growth habit; early response time; decorative-type inflorescences with elliptic-shaped ray florets; light yellow-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘Serginho’.
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 ‘Serginho’.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Hensbroek, The Netherlands. The objective of the program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform and vigorous plant growth and good post-production longevity.
The new Chrysanthemum originated from a cross-pollination made on Mar. 21, 2003 in Hensbroek, The Netherlands of a proprietary selection of Chrysanthemum×morifolium identified as code number 1002.34, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 98.1911.02, 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 Hensbroek, The Netherlands.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Hensbroek, The Netherlands on about Dec. 1, 2003. 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 Serginho 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 ‘Serginho’. These characteristics in combination distinguish ‘Serginho’ as a new and distinct Chrysanthemum:
    • 1. Upright, outwardly spreading and mounded plant habit.
    • 2. Freely branching growth habit.
    • 3. Early response time.
    • 4. Decorative-type inflorescences with elliptic-shaped ray florets.
    • 5. Light yellow-colored ray florets.
    • 6. Good postproduction longevity with plants maintaining good substance and color for about one month in an interior environment.
Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Chrysanthemum flower earlier than plants of the female parent selection.
    • 2. Inflorescences of plants of the new Chrysanthemum have darker yellow-colored ray florets than inflorescences of plants of the female parent selection.
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 in the following characteristics:
    • 1. Plants of the new Chrysanthemum have thicker stems than plants of the male parent selection.
    • 2. Inflorescences of plants of the new Chrysanthemum are more fully double than inflorescences of plants of the male parent selection.
    • 3. Inflorescences of plants of the new Chrysanthemum have darker yellow-colored ray florets than inflorescences of plants of the male parent selection.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Yoolympia, disclosed in U.S. Plant Pat. No. 14,814. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the cultivar Yoolympia in the following characteristics:
    • 1. Leaves of plants of the new Chrysanthemum were more pubescent than leaves of plants of the cultivar Yoolympia.
    • 2. Plants of the new Chrysanthemum flowered about three to four days earlier than plants of the cultivar Yoolympia.
    • 3. Inflorescences of plants of the new Chrysanthemum had fewer ray florets than inflorescences of plants of the cultivar Yoolympia.
    • 4. Plants of the new Chrysanthemum and the cultivar Yoolympia differed in ray floret shape and color.
Plants of the new Chrysanthemum can also be compared to plants of the cultivar Yoamarillo, disclosed in U.S. Plant Pat. No. 13,970. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the cultivar Yoamarillo in the following characteristics:
    • 1. Plants of the new Chrysanthemum were more compact than plants of the cultivar Yoamarillo.
    • 2. Plants of the new Chrysanthemum flowered about three to four days earlier than plants of the cultivar Yoamarillo.
    • 3. Inflorescences of plants of the new Chrysanthemum had fewer ray florets than inflorescences of plants of the cultivar Yoamarillo.
    • 4. Plants of the new Chrysanthemum and the cultivar Yoamarillo differed in ray floret shape.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ 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 typical flowering plants of ‘Serginho’.
The photograph on at the top of the second sheet comprises a top perspective view of typical flowering plants of ‘Serginho’.
The photograph at the bottom of the second sheet comprises a close-up view of the upper (left) and lower (right) surfaces of typical inflorescences and leaves of ‘Serginho’.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 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 summer in Hensbroek, The Netherlands, in a glass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, day temperatures ranged from 20° C. to 22° C. and night temperatures were about 19° C. Unrooted cuttings were directly stuck in 12-cm containers, exposed to long day/short night conditions, and pinched once about two weeks later. About one week after the pinch, the photoinductive short day/long night treatments were initiated.
