Description

LATIN NAME

Dendranthema morifolium.

VARIETY

`GEDI ONE IBE`.

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 IBE`.

This new cultivar originated from hybridization of a female parent, cultivar `Cassablanco` (unpatented in the United States), and a male parent cultivar `Papiro` (U.S. Plant Pat. No. 12,998). The new cultivar was discovered by the inventor in October 1997.

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 IBE` 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 IBE.` These characteristics in combination distinguish `GEDI ONE IBE` as a new and distinct Chrysanthemum:

1. Decorative type inflorescence;

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

3. Free branching habit;

4. White ray florets;

5. Very uniform round growth habit; and

6. Large quantity of blooms per flowering branch.

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

1. The new cultivar has more blooms per flowering branch;

2. The new cultivar has many more ray florets; and

3. The new cultivar has a wider diameter bloom.

Plants of the new cultivar are also similar to plants of the parent cultivar, `Papiro,` in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar `Papiro` in the following characteristics:

1. The new cultivar has a different flower type;

2. The new cultivar is taller and wider; and

3. The new cultivar has a wider diameter bloom.

The new cultivar can be compared to the Chrysanthemum cultivar `Odysseus` (disclosed in U.S. Plant Pat. No. 11,637). However plants of the new Chrysanthemum differed from the plants of the cultivar `Odysseus` in the following characteristics:

1. The new cultivar naturally blooms 2 weeks later;

2. The new cultivar has a more flexible plant habit;

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

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

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph shows a plant of `GEDI ONE IBE` grown in a 2-gallon container. A single cutting was used in the pot, planted mid-May and grown under outdoor field conditions.

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. The following observations and measurements describe plants grown in a commercial field in Oxnard, Calif. in the month of September 2000, 125 days from rooted cuttings. The growing conditions range from 60°C to 65°C F. at night to 70°C to 85°C F. during the day. Measurements and numerical values represent averages of typical flowering types.
