USPP18377P2 - Chrysanthemum plant named ‘GG GOSUN 05’ - Google Patents

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by upright daisy type inflorescences with spoon-shape ray florets, consistent flowering response to short days, blooming consistently after 52 days of short day length, yellow ray florets and a moderate branching habit.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘GG GOSUN 05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘GG GOSUN was origination from a cross made by Leo Van Zanten in a planned breeding program in October 2000 between the unpatented male parent ‘Tasman’ and the female parent ‘Red Delano’ (U.S. Plant Pat. No. 8,345). The new cultivar was discovered and selected by Leo Van Zanten in June 2001 in Oxnard, Calif.

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

• • 1. Daisy type inflorescence with an upright aspect;
  • 2. Yellow ray florets;
  • 3. Spoon-shape ray florets;
  • 4. And a moderate-branching habit.

Plants of the new cultivar ‘GG GOSUN 05’ are similar to plants of the male parent variety ‘Tasman’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOSUN 05’ have yellow ray florets compared to the white ray florets of the male parent. Also, the new cultivar ‘GG GOSUN 05’ has more yellow-green foliage than the male parent. Further, the new cultivar ‘GG GOSUN 05’ has spoon-type ray florets compared to the oblanceolate-shaped ray florets of the male parent.

Plants of the new cultivar ‘GG GOSUN 05’ are similar to plants of the female parent variety ‘Red Delano’ in most horticultural characteristics, however plants of the new cultivar ‘GG GOSUN 05’ have yellow ray florets compared to the dark red ray florets of the female parent. Also, ‘Red Delano’ has a decorative inflorescence form whereas ‘GG GOSUN 05’ has a daisy-type inflorescence form. Further, the new variety ‘GG GOSUN 05’ has spoon-type ray florets compared to the oblong-shaped ray florets of the female parent.

In comparison to the commercially available variety ‘Miramar’ (U.S. Plant Pat. No. 7,469), ‘GG GOSUN 05’ has an upright inflorescence aspect compared to the flat aspect of the comparable variety. Additionally, the new variety ‘GG GOSUN 05’ has a smaller inflorescence diameter. Further, the new variety ‘GG GOSUN 05’ different color ray and disc florets than the comparable variety.
