Chrysanthemum plant named ‘Gedi Two Ylnov’

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by a decorative-type inflorescence, consistent flowering response to short days, blooming consistently after 49 days of short day length, free branching habit, yellow ray florets, a very uniform round growth habit, and a large quantity of blooms per flowering branch.

Description

Latin name of the genus and species: The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum morifolium.

Variety denomination: The new and distinct Chrysanthemum plant is hereinafter referred to by the cultivar name ‘Gedi Two Ylnov.’

BACKGROUND OF THE INVENTION

The new cultivar is a natural mutation that occurred on a single branch of a plant of the Chrysanthemum cultivar ‘Novare Orange’ (undistributed in the United States). The new cultivar was discovered and asexually propagated 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 cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Gedi Two Ylnov’ 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 Two Ylnov.’ These characteristics in combination distinguish ‘Gedi Two Ylnov’ as a new and distinct Chrysanthemum cultivar:

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. Yellow 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, ‘Novare Orange’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Novare Orange’ primarily in ray floret color. The inflorescences of the new cultivar also have a smaller diameter than those of the parent variety.

In comparison to the commercially available variety ‘Cleagar GF 1’ (U.S. Plant Pat. No. 10,463), ‘Gedi Two Ylnov’ has a more round plant shape and greater branching, more blooms per flowering branch, and a flatter inflorescence.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The photograph shows a plant of ‘Gedi Two Ylnov’ in a six-inch container. One cutting was used in the pot.

DETAILED BOTANICAL DESCRIPTION
