Chrysanthemum plant named ‘Gedi Three Pyel’

Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by a somewhat open-centered flower with bright yellow ray florets, and a mounding, free-branching growth habit. The new variety naturally blooms in the first two weeks of September.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘Gedi Three Pyel’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of an induced mutation produced from the parent Chrysanthemum plant variety ‘Gedi Two Pad’ (U.S. Plant Pat. No. 14,501) using gamma ray treatment at a dose of 20 Gy. The new cultivar was discovered and selected by Dirk Pieters in a controlled environment in Oostnieuwkerke, Belgium, in September, 2002.

Asexual reproduction of the new cultivar ‘Gedi Three Pyel’ by terminal cuttings and 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 Three Pyel’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 Three Pyel.’ These characteristics in combination distinguish ‘Gedi Three Pyel’ as a new and distinct Chrysanthemum cultivar:

• • 1. The ray florets are bright yellow.
  • 2. The flower has a somewhat open center.
  • 3. The plant has a mounding growth habit.
  • 4. The plant is free branching.
  • 5. The plant has an early natural season bloom response in the first two weeks of September.

Plants of the new cultivar ‘Gedi Three Pyel’ are similar to plants of the parent variety, ‘Gedi Two Pad,’ in most horticultural characteristics. However, plants of the new cultivar have yellow ray florets, while the parent variety ‘Gedi Two Pad’ has pink ray florets.

In comparison to the commercially available variety ‘Gedi One Avi’ (U.S. Plant Pat. No. 13,455), the new variety ‘Gedi Three Pyel’ has less ray florets on each flower, and has approximately 12 more flowers per flowering branch.

In comparison to the commercially available variety ‘Gedi One Ces’ (U.S. Plant Pat. No. 13,797), the new variety ‘Gedi Three Pyel’ has approximately 9 more flowers per flowering branch, and has a wider but shorter leaf.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Gedi Three Pyel’ grown in a 2 gallon container. One cutting was used in the pot. The colors are as nearly true as is reasonably possible in a color representation of this type.
