Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by small anemone-type inflorescences, consistent flowering response to short days, blooming consistently after 51 days of short day length, pure white ray florets; a yellow disc with a green eye, and a free branching habit.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: GG GOBI 08.

BACKGROUND OF THE INVENTION

The new cultivar ‘GG GOBI 08’ is a product of a cross between the male parent ‘Davis’ (U.S. Plant Pat. No. 7,325) and the female parent ‘TTI101’ (unpatented). The new cultivar was discovered and selected by Leo Van Zanten in August of 2003 in Oxnard, Calif.

Asexual reproduction of the new cultivar ‘GG GOBI 08’ by terminal cuttings was performed in Oxnard, Calif., and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘GG GOBI 08’ 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 ‘GG GOBI 08.’ These characteristics in combination distinguish ‘GG GOBI 08’ as a new and distinct Chrysanthemum cultivar:

- 1. Small, white anemone-type inflorescences;
- 2. Yellow disc with a green eye;
- 3. Free branching habit; and
- 4. Consistent flowering response to short days, blooming consistently after 51 days of short day length.

Plants of the new cultivar ‘GG GOBI 08’ are similar to plants of the male parent variety, ‘Davis’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOBI 08’ have a larger plant spread. Also, the new cultivar ‘GG GOBI 08’ has a smaller inflorescence diameter and longer inflorescence longevity. Additionally, the ray florets of ‘GG GOBI 08’ are a different color than the male parent. Finally, ‘GG GOBI 08’ has a shorter response time.

Plants of the new cultivar ‘GG GOBI 08’ are similar to plants of the female parent variety, ‘TTI101’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOBI 08’ are shorter but have a wider plant spread. Also, the new cultivar ‘GG GOBI 08’ has a smaller inflorescence diameter. Additionally, the ray florets of ‘GG GOBI 08’ are white compared to the yellow ray florets of the female parent. Finally, ‘GG GOBI 08’ has a shorter response time.

In comparison to the commercially available variety ‘Tasman’ (not patented in the United States), ‘GG GOBI 08’ is shorter and wider. Additionally, the new variety ‘GG GOBI 08’ has a smaller inflorescence diameter and more pure white ray florets. Further, the new variety ‘GG GOBI 08’ has a more consistently yellow disc with a green heart, compared to the mostly darker green disc of the comparable variety. Finally, ‘GG GOBI 08’ has longer inflorescence longevity.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘GG GOBI 08’ grown in a 6 inch container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions. The colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
