ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as
Argyranthemum frutescens
and referred to by the cultivar name Sugar Button.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program was to develop compact and freely-flowering Marguerite daisies that have inflorescences with good form and floret color.
The new cultivar originated from a cross made by the Inventor in 1993 of a proprietary selection of
Argyranthemum frutescens
identified as number AB5003, as the male or pollen parent, with a proprietary selection of
Argyranthemum frutescens
identified as number
AB
50052, as the female or seed parent. The cultivar Sugar Button was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Cobbitty, New South Wales, Australia.
Plants of the new Marguerite Daisy are different from plants of the male parent, the selection number AB5003, in plant height, plant diameter, leaf color, inflorescence size and ray floret color.
Plants of the new Marguerite Daisy are different from plants of the female parent, the selection number AB50052, in plant diameter, inflorescence size and ray floret color.
Asexual reproduction of the new cultivar by terminal cuttings and by tissue culture in Cobbitty, New South Wales, Australia, has shown that the unique features of this new Marguerite Daisy are stable and are reproduced true to type in successive propagations.
SUMMARY OF THE INVENTION
The new cultivar 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 characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Sugar Button’ which distinguish ‘Sugar Button’ as a new and distinct cultivar:
1. Upright, mounding and compact plant habit.
2. Green-colored stems, no anthocyanin.
3. Freely branching, dense plants with short internodes.
4. Freely flowering with numerous inflorescences per plant.
5. Medium-sized anemone-type inflorescences.
6. Pure white ray and bright yellow disc florets that gradually become white with development.
Plants of the new Marguerite Daisy can be compared to plants of the cultivar Sugar and Ice, disclosed in U.S. Plant Pat. No. 11,040. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Marguerite Daisy are slightly taller and more narrow than plants of the cultivar Sugar and Ice. In addition, plants of the new Marguerite Daisy have shorter leaves and smaller inflorescences than plants of Sugar and Ice.
