Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP PAD WH05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP PAD WH05’ is a product of an induced mutation of 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 September 2002 in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP PAD WH05’ 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 PAD WH05’ 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 PAD WH05’. These characteristics in combination distinguish ‘PPP PAD WH05’ 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 first week of September.

Plants of the new cultivar are similar to plants of the parent variety, ‘GEDI TWO PAD,’ in most horticultural characteristics, however the new cultivar ‘PPP PAD WH05’ is shorter than the parent and has more ray florets. Additionally, the new variety ‘PPP PAD WH05’ has different color ray florets than the parent ‘GEDI TWO PAD’ and has a more apparent disc than the parent.

In comparison to the commercially available variety ‘GEDI ONE TER’ (U.S. Plant Pat. No. 13,885), ‘PPP PAD WH05’ shows disc florets with age. Additionally, the new variety ‘PPP PAD WH05’ naturally blooms one week later than the comparable variety. Further, the new variety ‘PPP PAD WH05’ has more inflorescence per flowering branch and has less ray florets per inflorescence than the comparable variety ‘GEDI ONE TER.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PPP PAD WH05’ 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.
