GENUS AND SPECIES
Anthurium andreanum L.
VARIETY DENOMINATION
‘ANTHDOZAL’
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHDOZAL’. The new variety originated from a naturally occurring, single plant mutation found in a production clone of ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in Bleiswijk, The Netherlands. The original variety is a red Anthurium pot plant designated ‘ANTHEPEDI’.
A single plant was selected in January 2006 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a five-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this variety have been applied for in Europe on Apr. 25, 2013. ‘ANTHDOZAL’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands.
1) Pink spathes;
2) White spadix;
3) Rich shoot formation;
4) Compact plant habit; and
5) Green foliage.
DESCRIPTION OF THE PHOTOGRAPH
This new Anthurium plant is illustrated by the accompanying photograph which shows the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a 60-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2014.
DESCRIPTION OF THE NEW VARIETY
The following detailed description sets forth the distinctive characteristics of ‘ANTHDOZAL’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 60-week old plants which were planted from tissue culture in 14-cm pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in February 2014. Color readings were taken under 5000 lux natural light in the greenhouse: Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

- Flowering time:
- General.—One small rooted untreated tissue culture plant of 4 cm tall will flower after 6 to 8 months, depending on the season, and 2 to 4 blossoms appear. More blossoms appear after some additional weeks so that a full flowering and commercial plant will have 6 to 8 pink spathes. Smaller blossoms may occur on less mature plants.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES
‘ANTHDOZAL’ differs from the natural mutation parent and commercial variety ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in that ‘ANTHDOZAL’ has pink spathes (RHS 52A), whereas ‘ANTHEPEDI’ has red spathes (RHS 45B).
‘ANTHDOZAL’ differs from commercial variety ‘ANTHCORYO’ (unpatented) in that ‘ANTHDOZAL’ has stronger shoot formation and slightly blistered spathes, whereas ‘ANTHCORYO’ has weak shoot formation and unblistered spathes.
‘ANTHDOZAL’ can be compared to commercial varieties Anthurium ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) and ‘ANTHCORYO’ (unpatented). Additional comparison data is shown in Table 1 below.
