| Abstract: |
A new and distinct cultivar of Argyranthemum plant named `Supait339`, characterized by its compact, mounded, upright and outwardly spreading plant habit; freely branching habit, dense and bushy plants; freely flowering habit with numerous inflorescences per plant; anemone-type inflorescence form with white-colored ray florets and yellow-colored disc florets. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Argyranthemum plant named `Supait339`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar denomination: Argyranthemum frutescens cultivar Supait339.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Argyranthemum plant, botanically known as Argyranthemum frutescens and hereinafter referred to by the cultivar name `Supait339`.
The new Argyranthemum is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the program is to create and develop new compact Argyranthemum cultivars with numerousinflorescences, interesting inflorescence form, and attractive ray floret coloration.
The new Argyranthemum originated from a cross-pollination by the Inventor in September, 2000, of the Argyranthemum frutescens cultivar Summer Melody, disclosed in U.S. Plant Pat. No. 11,763, as the female, or seed, parent, with theArgyranthemum frutescens cultivar Sam, not patented, as the male, or pollen, parent. The new Argyranthemum was discovered and selected by the Inventor as a plant within the progeny of the stated cross-pollination in a controlled environment in Cobbitty,New South Wales, Australia in September, 2001. The selection of the new Argyranthemum was based on its attractive inflorescence form and ray floret coloration.
Asexual reproduction of the new Argyranthemum by terminal cuttings taken in a controlled environment in Cobbitty, New South Wales, Australia since September, 2001, has shown that the unique features of this new Argyranthemum are stable andreproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Argyranthemum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of `Supait339` and distinguish the new Argyranthemum as a new and distinct cultivar: 1. Compact, mounded, upright and outwardly spreadingplant habit. 2. Freely branching habit, dense and bushy plants. 3. Freely flowering habit with numerous inflorescences per plant. 4. Anemone inflorescence form with white-colored ray florets and yellow-colored disc florets.
Plants of the new Argyranthemum differ from plants of the female parent, the cultivar Summer Melody, in inflorescence form and ray floret coloration as plants of the cultivar Summer Melody have double-type inflorescences and pink-colored rayflorets. Plants of the new Argyranthemum differ from plants of the male parent, the cultivar Sam, in inflorescence form and ray floret coloration as plants of the cultivar Sam have daisy-type inflorescences and primrose-colored ray florets.
Plants of the new Argyranthemum differ from plants of the cultivar Supalav, disclosed in U.S. Plant patent application Ser. No. 10/818,517 and the cultivar Supamon, disclosed in U.S. Plant patent application Ser. No. 10/818,516, primarily infloret coloration. Plants of the new Argyranthemum differ from plants of the cultivar Supasat, disclosed in U.S. Plant patent application Ser. No. 10/818,494, in inflorescence form and floret coloration.
Plants of the new Argyranthemum can be compared to plants of the cultivar Summer Angel, disclosed in U.S. Plant Pat. No. 11,085. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Argyranthemumdiffered from plants of the cultivar Summer Angel in the following characteristics: 1. Plants of the new Argyranthemum were more compact than plants of the cultivar Summer Angel. 2. Plants of the new Argyranthemum and the cultivar Summer Angeldiffered in disc floret coloration as plants of the cultivar Summer Angel had white-colored disc florets. 3. Plants of the new Argyranthemum had shorter peduncles than plants of the cultivar Summer Angel.
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 colors of the new Argyranthemum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Supait339` grown in a one-gallon container.
The photograph at the bottom of the sheet comprises a close-up view of inflorescences of `Supait339`.
