USPP19268P2 - Chrysanthemum plant named ‘PPP ALB WH06’ - Google Patents

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, pure white outer ray florets and creamy yellow inner ray florets, free branching habit, and a consistent natural season flowering habit during the last week of September.

Description

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP ALB WH06’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP ALB WH06’ is a product of a cross between the male present ‘Bardi’ (not patented in the United States) and the female parent ‘GEDI THREE SIE’ (U.S. Plant Pat. No. 16,875). The new cultivar was discovered and selected by Dirk Pieters in September of 2002 in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP ALB WH06’ by terminal cuttings 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 ALB WH06’ 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 ALB WH06.’ These characteristics in combination distinguish ‘PPP ALB WH06’ as a new and distinct Chrysanthemum cultivar:

• • 1. Large, white decorative-type inflorescences with a creamy yellow center;
  • 2. Free branching habit;
  • 3. Consistent natural season flowering habit during the last week of September; and
  • 4. Consistent flowering response to short days, blooming consistently after 49 days of short day length.

Plants of the new cultivar ‘PPP ALB WH06’ are similar to plants of the male parent variety, ‘Bardi’ in most horticultural characteristics; however plants of the new cultivar ‘PPP ALB WH06’ are taller and wider. Also, the new cultivar ‘PPP ALB WH06’ has more inflorescences per lateral branch. Finally, ‘PPP ALB WH06’ naturally blooms three weeks earlier.

Plants of the new cultivar ‘PPP ALB WH06’ are similar to plants of the female parent variety, ‘GEDI THREE SIE’ in most horticultural characteristics; however plants of the new cultivar ‘PPP ALB WH06’ are shorter in height. Also, the new cultivar ‘PPP ALB WH06’ blooms three to four weeks later. Additionally, the female parent ‘GEDI THREE SIE’ has more inflorescences per lateral branch. Finally, the inflorescences of ‘PPP ALB WH06’ are white with a creamy yellow center while the inflorescences of the female parent ‘GEDI THREE SIE’ are orange.

In comparison to the commercially available variety ‘GEDI THREE MIL’ (U.S. Plant Pat. No. 16,843), ‘PPP ALB WH06’ has a wider plant spread. Additionally, the new variety ‘PPP ALB WH06’ has a smaller inflorescence diameter. Further, the new variety ‘PPP ALB WH06’ does not have as many inflorescences per lateral branch nor as many ray florets per inflorescence as the comparable variety. Finally, the ray florets of ‘PPP ALB WH06’ are whiter with a more yellow-orange center than the comparable variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a typical plant of ‘PPP ALB WH06’ grown in a 2 gallon container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions. The color are as nearly true as is reasonably possible in a color representation of this type.
