Abstract

A new and distinct Chrysanthemum plant variety characterized by a daisy type inflorescence, consistent flowering response to short days, blooming consistently after 49 days of short day length, free branching habit, compact growth habit, and highly floriferous plants.

Description

LATIN NAME

Dendranthema morifolium.

VARIETY

‘Gedi One Ost’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, herein after referred to by the cultivar name ‘Gedi One Ost.’

This new cultivar originated from hybridization of a female parent Chrysanthemum cultivar ‘Ballino’ (U.S. Plant patent application Ser. No. 09/550,159, now abandoned) with a male parent Chrysanthemum cultivar ‘Sunny Tripoli’ (unpatented in the United States). The new cultivar was discovered by the inventor in October 1996.

Asexual reproduction of the new cultivar by apical tip cutting and meristem tissue culture 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 ‘Gedi One Ost’ 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 ‘Gedi One Ost.’ These characteristics in combination distinguish ‘Gedi One Ost’ as a new and distinct Chrysanthemum:

1. Daisy type inflorescence;

2. Consistent flowering response to short days, blooming consistently after 49 days of short day length;

3. Free branching habit;

4. Compact growth habit; and

5. Highly floriferous plants.

Plants of the new cultivar are similar to plants of the parent cultivar, ‘Ballino,’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Ballino’ in the following characteristics:

1. The new cultivar naturally blooms 1 week later; and

2. The new cultivar has larger diameter blooms.

Plants of the new cultivar are similar to plants of the parent cultivar, ‘Sunny Tripoli,’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Sunny Tripoli’ in the following characteristics:

1. The new cultivar has more ray florets;

2. The new cultivar has a more round, uniform plant shape; and

3. The new cultivar naturally blooms 1 week later.

The new cultivar can be compared to the Chrysanthemum cultivar ‘Yellow Tripoli’ (disclosed in U.S. Plant Pat. No. 11,725). However plants of the new Chrysanthemum differed from the plants of the cultivar ‘Yellow Tripoli’ in the following characteristics:

1. The new cultivar has more ray florets;

2. The new cultivar has a more round plant shape and greater branching;

3. The new cultivar has a shorter internode length; and

4. The new cultivar has more blooms per flowering branch.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph shows a plant of ‘Gedi One Ost’ grown in an 8-inch container. A single cutting was used in the container.

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.
