It is claimed:

1. A new and distinct cultivar of Chrysanthemum plant named ‘Golden Surfer’, as illustrated and described.

Description:

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Golden Surfer’.

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 ‘Golden Surfer’.

The new Chrysanthemum is the product of a planned breeding program conducted by the Inventor in Staden, Belgium. The objective of the breeding program is to develop new garden Chrysanthemums with a flowering date of mid-September, unique inflorescence forms, attractive ray and disc coloration and good resistance to wind and rain.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in September, 2000, in Staden, Belgium, of the Chrysanthemum×morifolium cultivar Bronia, not patented, as the female, or seed, parent with the Chrysanthemum×morifolium cultivar Rumba, disclosed in U.S. Plant Pat. No. 8,462, 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 stated cross-pollination in a controlled environment in Staden, Belgium.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in Staden, Belgium since November, 2001, 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 Golden Surfer 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 ‘Golden Surfer’. These characteristics in combination distinguish ‘Golden Surfer’ as a new and distinct cultivar:

    • 1. Upright and rounded growth habit.
    • 2. Freely branching growth habit.
    • 3. Uniform and freely flowering habit.
    • 4. Duplex-type inflorescences with bright yellow-colored ray florets and yellow green-colored disc florets.
    • 5. Excellent garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female parent, the cultivar Bronia. In side-by-side comparisons conducted in Staden, Belgium, plants of the new Chrysanthemum differed from plants of the cultivar Bronia in the following characteristics:

    • 1. Plants of the new Chrysanthemum flowered about 39 days earlier than plants of the cultivar Bronia grown under natural season conditions.
    • 2. Plants of the new Chrysanthemum and the cultivar Bronia differed in inflorescence form and ray floret coloration.

Plants of the new Chrysanthemum can be compared to plants of the male parent, the cultivar Rumba. In side-by-side comparisons conducted in Staden, Belgium, plants of the new Chrysanthemum differed from plants of the cultivar Rumba in the following characteristics:

    • 1. Plants of the new Chrysanthemum flowered about 44 days earlier than plants of the cultivar Rumba grown under natural season conditions.
    • 2. Plants of the new Chrysanthemum and the cultivar Rumba differed in inflorescence form and ray floret coloration.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Pjhavan, disclosed in U.S. Plant Pat. No. 14,268. In side-by-side comparisons conducted in Staden, Belgium, plants of the new Chrysanthemum differed from plants of the cultivar Pjhavan in the following characteristics:

    • 1. Plants of the new Chrysanthemum were more rounded in form than and not as upright as plants of the cultivar Pjhavan.
    • 2. Plants of the new Chrysanthemum flowered about two weeks earlier than plants of the cultivar Pjhavan grown under natural season conditions.
    • 3. Inflorescences of plants of the new Chrysanthemum were smaller than inflorescences of plants of the cultivar Pjhavan.
    • 4. Plants of the new Chrysanthemum and the cultivar Pjhavan differed in ray floret coloration.

Plants of the new Chrysanthemum can also be compared to plants of the cultivar Orka, not patented. In side-by-side comparisons conducted in Staden, Belgium, plants of the new Chrysanthemum differed from plants of the cultivar Orka in the following characteristics:

    • 1. Plants of the new Chrysanthemum were larger and more rounded in form than plants of the cultivar Orka.
    • 2. Plants of the new Chrysanthemum flowered about four days earlier than plants of the cultivar Orka grown under natural season conditions.
    • 3. Plants of the new Chrysanthemum and the cultivar Orka differed in inflorescence form and ray floret coloration.
    • 4. Plants of the new Chrysanthemum were not sensitive to Rust infection whereas plants of the cultivar Orka were sensitive to Rust infection.

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 colors of the new Chrysanthemum.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Golden Surfer’.

The photograph at the bottom of the sheet comprises a close-up view of the upper and lower surfaces of typical leaves (top) and typical inflorescences (bottom) of ‘Golden Surfer’.

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 summer and fall in Oostnieuwkerke-Staden, Belgium, under commercial practice in an outdoor nursery. During the production of the plants, day temperatures averaged 15° C. and night temperatures averaged 13° C. Plants were pinched about two weeks after planting. Plants were about four months from planting into 19-cm containers when the photographs and the description were taken.
