Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘ATH THREE YTLG’.

BACKGROUND OF THE INVENTION

The new cultivar ‘ATH THREE YTLG’ is a discovered natural mutation of the parent variety ‘CGG TNG8’ (U.S. Plant Pat. No. 11,740). The new cultivar ‘ATH THREE YTLG’ was discovered and selected by Lucilene Anatriello in May, 2001, in San Jose Do Rio Preto, State of Sao Paulo, Brazil. The new variety was discovered and selected as a natural mutation which was present on a single branch of the parent variety that was growing in a controlled environment in a plot of approximately 100 plants of the parent variety.

Asexual reproduction of the new cultivar ‘ATH THREE YTLG’ by terminal cuttings and tissue culture was performed in a controlled environment in Oxnard, Calif. and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ATH THREE YTLG’ 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 in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ATH THREE YTLG.’ These characteristics in combination distinguish ‘ATH THREE YTLG’ as a new and distinct Chrysanthemum cultivar:

    • 1. The new variety has a yellow-colored daisy-type flower.
    • 2. The plant has a very round shape.
    • 3. The new variety flowers prolifically.
    • 4. The plant is free-branching and flexible.
    • 5. The plant has medium vigor.
    • 6. The new variety naturally blooms in the last week of August.

Plants of the new cultivar ‘ATH THREE YTLG’ are similar to plants of the parent variety, ‘CGG TNG8,’ in most horticultural characteristics. Plants of the new cultivar ‘ATH THREE YTLG’ have ray florets that are a different color than the ray florets of the parent variety.

In comparison to the commercially available variety ‘GEDI YT8’ (U.S. Plant Pat. No. 11,725), ‘ATH THREE YTLG’ has more ray florets and a flower that lasts approximately nine days longer than the comparable variety. Additionally, the new variety ‘ATH THREE YTLG’ naturally blooms about three to four weeks earlier than the comparable variety ‘GEDI YT8.’

In comparison to the commercially available variety ‘GEDI TWO YLATL’ (U.S. Plant Pat. No. 14,482), ‘ATH THREE YTLG’ has more numerous ray florets that are lighter yellow in color. The flower of the new variety ‘ATH THREE YTLG’ has a larger diameter than the flower of the comparable variety. Further, the new variety ‘ATH THREE YTLG’ has approximately 13 fewer flowers per stem than the comparable variety ‘GEDI TWO YLATL.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘ATH THREE YTLG’ grown in a 6-inch container. One cutting was used in the pot. The colors are as nearly true as is reasonably possible in a color representation of this type.
