| Abstract: |

| Claim: |
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named `Dekspits`, as illustrated and described. |
| Description: |
Botanicaldesignation: Chrysanthemum.times.morifolium.
Cultivar denomination: `Dekspits`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium and referred to by the name `Dekspits`.
The new Chrysanthemum is the product of a planned breeding program conducted by the Inventor in Hensbroek, The Netherlands. The objective of the breeding program is to create new cut Chrysanthemum cultivars with interesting inflorescence formsand attractive floret coloration.
The new Chrysanthemum originated from a cross-pollination made by the Inventor on Feb. 25, 2002, in Hensbroek, The Netherlands, of a proprietary selection of Chrysanthemum identified as code number 5000,97, not patented, as the female, or seed,parent with a proprietary Chrysanthemum selection identified as code number 5003,60, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single plant within the progeny of the statedcross-pollination in a controlled environment in Hensbroek, The Netherlands.
Asexual reproduction of the new Chrysanthemum by terminal cuttings in Hensbroek, The Netherlands since January, 2003, 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 Dekspits has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length and light intensity, without, however, any variance ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Dekspits`. These characteristics in combination distinguish `Dekspits` as a new and distinct cutlivar: 1. Large decorative spider-typeinflorescences with quilled-shaped, yellow green to pale yellow-colored ray florets; typically grown as a single stem-type. 2. Strong and upright flowering stems. 3. Early and uniform flowering response. 4. Good postproduction longevity.
Plants of the new Chrysanthemum can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the female parent selection inthe following characteristics: 1. Plants of the new Chrysanthemum were more vigorous than plants of the female parent selection. 2. Plants of the new Chrysanthemum flowered earlier than plants of the female parent selection. 3. Color of developingray florets of plants of the new Chrysanthemum was lighter green than color of developing ray florets of the female parent selection.
Plants of the new Chrysanthemum can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the male parent selection in thefollowing characteristics: 1. Plants of the new Chrysanthemum flowered earlier than plants of the male parent selection. 2. Plants of the new Chrysanthemum had smaller ray florets than plants of the male parent selection. 3. Plants of the newChrysanthemum and the male parent selection differed in ray floret coloration as plants of the male parent selection had white-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Anastasia Yellow, disclosed in U.S. Plant Pat. No. 14,293. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the newChrysanthemum differed primarily from plants of the cultivar Anastasia Yellow in the following characteristics: 1. Plants of the new Chrysanthemum were more vigorous than plants of the cultivar Anastasia Yellow. 2. Plants of the new Chrysanthemum hadshorter ray florets than plants of the cultivar Anastasia Yellow. 3. Plants of the new Chrysanthemum and the cultivar Anastasia Yellow differed in ray floret coloration as plants of the cultivar Anastasia Yellow had 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 slightlyfrom the color values cited in the detailed botanical description which accurately describe the actual colors of the new Chrysanthemum.

The photograph at the bottom left of the sheet comprises a close-up view of upper surface of a typical inflorescence and a typical leaf of `Dekspits`.
The photograph at the bottom right of the sheet comprises a close-up view of lower surface of a typical inflorescence and a typical leaf of `Dekspits`.
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 followingobservations and measurements describe plants grown during the summer and autumn in Hensbroek, The Netherelands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by shortday/long night treatments to induce flower initiation and developement. During the production of the plants, day temperatures ranged from 17.5 to 30.degree. C., night temperatures ranged from 18.5 to 24.degree. C. and light levels were about fivekilolux. Plants were pinched once and were about ten weeks from planting when the photographs and the description were taken. Botanical classification: Chrysanthemum.times.morifolium cultivar Dekspits. Commercial classification: Decorative spider-typeChrysanthemum typically grown as a single stem-type cut flower. Parentage: Female or seed parent.--Proprietary selection of Chrysanthemum.times.morifolium identified as code number 5000,97, not patented. Male or pollen parent.--Proprietary selection ofChrysanthemum.times.morifolium identified as code number 5003,60, not patented. Propagation: Type.--Terminal tip cuttings. Time to initiate roots, summer.--About 6 days at 20.degree. C. Time to initiate roots, winter.--About 7 days at 20.degree. C.Time to produce a rooted cutting, summer.--About 14 days at 20.degree. C.
