Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘GG GOBTW 05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘GG GOBTW 05’ was originated from a cross made by Leo Van Zanten in a planned breeding program in December 2001 between the male parent ‘Tijuana’ (U.S. Plant Pat. No. 9,083) and the unpatented female parent ‘Mackenzie.’ The new cultivar was discovered and selected by Leo Van Zanten in August 2002 in Oxnard, Calif.

Asexual reproduction of the new cultivar ‘GG GOBTW 05’ by vegetative 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 GOBTW 05’ 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 GOBTW 05.’ These characteristics in combination distinguish ‘GG GOBTW 05’ as a new and distinct Chrysanthemum cultivar:

    • 1. Small daisy type inflorescence;
    • 2. Light purple and creamy white bi-color ray florets;
    • 3. Moderate-branching habit;
    • 4. And blooming consistently after 52 days of short day length.

Plants of the new cultivar ‘GG GOBTW 05’ are similar to plants of the male parent, ‘Tijuana’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOBTW 05’ has more lavender ray florets with pale yellow bands compared to the red-purple ray florets with white bands of the parent. Additionally, the new variety ‘GG GOBTW 05’ has a smaller inflorescence diameter. Further, the new variety ‘GG GOBTW 05’ has more green foliage compared to the dark yellow-green of the parent ‘Tijuana.’

Plants of the new cultivar ‘GG GOBTW 05’ are similar to plants of the female parent, ‘Mackenzie’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOBTW 05’ are bi-color ray florets compared to the single color purple ray florets of the female parent. Also, ‘GG GOBTW 05’ has yellow disc florets compared to the yellow-green disc florets of the female parent. Finally, the ray florets of the new cultivar ‘GG GOBTW 05’ are a much lighter purple than the dark purple ray florets of the female parent.

In comparison to the commercially available variety ‘New Yoorleans’ (U.S. Plant Pat. No. 11,215), the bi-color ray florets of ‘GG GOBTW 05’ are lavender and pale yellow compared to the dark red-purple and white bi-color ray florets of the comparable variety. Additionally, the new variety ‘GG GOBTW 05’ is smaller in both height and plant spread. Further, the new variety ‘GG GOBTW 05’ has more true green foliage and a smaller inflorescence diameter than the comparable variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘GG GOBTW 05’ grown in a 6.5-inch container. Five cuttings were used in the pot, planted late October and grown in a greenhouse. The colors are as nearly true as is reasonably possible in a color representation of this type.
