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, pink two tone ray florets, free branching habit, and a consistent natural season flowering habit during early September.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP MIL PK05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP MIL PK05’ is a product of induced mutation of the parent Chrysanthemum plant variety ‘GEDI THREE MIL’, U.S. Plant patent application Ser. No. 11/118,273, using gamma ray treatment at a dose of 20 Gy. The new cultivar was discovered and selected by Dirk Pieters in September 2003 in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP MIL PK05’ 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 MIL PK05’ 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 MIL PK05.’ These characteristics in combination distinguish ‘PPP MIL PK05’ as a new and distinct Chrysanthemum cultivar:

- 1. Pink two-tone 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 in early September.

Plants of the new cultivar ‘PPP MIL PK05’ are similar to plants of the parent variety, ‘GEDI THREE MIL’ in most horticultural characteristics, however the new cultivar ‘PPP MIL PK05’ is taller than the parent and has more ray florets. Additionally, the new variety ‘PPP MIL PK05’ has different color ray florets than the parent ‘GEDI THREE MIL’.

In comparison to the commercially available variety ‘GEDI TWO CAN’ (U.S. Plant Pat. No. 14,474), ‘PPP MIL PK05’ has a darker center in the bloom. Additionally, the new variety ‘PPP MIL PK05’ naturally blooms approximately fifteen days earlier than the comparable variety. Further, the new variety ‘PPP MIL PK05’ has a larger diameter inflorescence and has more inflorescence per flowering branch than the comparable variety ‘GEDI TWO CAN.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PPP MIL PK05’ 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

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.
