Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP CON Y05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP CON Y05’ is a product of an induced mutation of the parent Chrysanthemum plant variety ‘PPP CON OR05’ (U.S. Plant Pat. No. 18,094) 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 CON Y05’ by terminal cuttings and tissue culture was performed in Oostnieuwkerke, Belgium and Oxnard, Calif., 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 CON 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 CON Y05.’ These characteristics in combination distinguish ‘PPP CON Y05’ as a new and distinct Chrysanthemum cultivar:

    • 1. Large bright yellow inflorescences;
    • 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 second week of September.

Plants of the new cultivar ‘PPP CON Y05’ are similar to plants to the parent variety, ‘PPP CON OR05,’ in most horticultural characteristics, however plants of the new cultivar ‘PPP CON Y05’ are smaller in height than the parent. Also, ‘PPP CON Y05’ have a larger inflorescence diameter. Finally, the ray florets of ‘PPP CON Y05’ are bright yellow compared to the orange ray florets of the parent.

In comparison to the commercially available variety ‘GEDI ONE AVI’ (U.S. Plant Pat. No. 13,455), ‘PPP CON Y05’ has a much wider plant spread. Additionally, the new variety ‘PPP CON Y05’ has lighter, greener foliage. Further, the new variety ‘PPP CON Y05’ has a longer inflorescence longevity and the ray florets are a much brighter, truer yellow than the yellow-orange ray florets of the comparable variety ‘GEDI ONE AVI.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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