Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by large decorative type inflorescences, consistent flowering response to short days, blooming consistently after 49 days of short day length, bright yellow ray florets, free branching habit, and a consistent natural season flowering habit during the last two weeks of August.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP TER Y05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP TER Y05’ is a product of an induced mutation of the parent Chrysanthemum plant variety ‘GEDI ONE TER’ (U.S. Plant Pat. No. 13,885) using gamma ray treatment at a dose of 20 Gy. The new cultivar was discovered and selected by Dirk Pieters in October 2003 in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP TER Y05’ by terminal cuttings and tissue culture was performed in Oostnieuwkerke, Belgium, 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 ‘PPP TER Y05’ 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 ‘PPP TER Y05’. These characteristics in combination distinguish ‘PPP TER Y05’ as a new and distinct Chrysanthemum cultivar:

- 1. Large decorative type inflorescence;
- 2. Consistent flowering response to short days, blooming consistently after 49 days of short day length;
- 3. Free branching habit; and
- 4. Consistent natural season flowering habit during the last two weeks of August.

Plants of the new cultivar ‘PPP TER Y05’ are similar to plants of the parent variety, ‘GEDI ONE TER’, in most horticultural characteristics, however plants of the new cultivar ‘PPP TER Y05’ has more ray florets than the ray florets of the parent variety. Additionally, the new variety is shorter than the parent and also has different color ray florets than the parent.

In comparison to the commercially available variety ‘GEDI ONE YLCEL’ (U.S. Plant Pat. No. 13,903). ‘PPP TER Y05’ has brighter yellow ray florets. Additionally, the new variety ‘PPP TER Y05’ naturally blooms approximately three weeks earlier than the comparable variety. Further, the new variety ‘PPP TER Y05’ has a larger diameter inflorescence and has more inflorescence per flowering branch than the comparable variety ‘GEDI ONE YLCEL’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PPP TER Y05’ grown in a 2 gallon container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions. The colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION
