VARIETY DENOMINATION

‘ANTHDINWAQ’

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 ‘ANTHDINWAQ’. The new variety originated from a hybridization made in October 2004 in Bleiswijk, The Netherlands. The female parent is a purple-pink Anthurium pot plant named ‘ANTHUCOEN’ (U.S. Plant Pat. No. 22,630) and the male parent is a pink Anthurium plant named ‘ANTHBESKA’ (unpatented).

The new variety was selected in September 2006 from a selection of the hybridization 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 Nov. 19, 2012. ‘ANTHDINWAQ’ 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) A bright glossy pink colored small sized spathe;
  • 2) Purple spadix;
  • 3) Glossy leaves; and
  • 4) Very compact plant habit.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show 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 photographs are of a 48-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2012.

FIG. 3 shows the leaf in 2 ages.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDINWAQ’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 48-week old plants which were planted from tissue culture in 12-cm pots and grown in a greenhouse between 19° C. and 24° C. Observations were made in February 2013. 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).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDINWAQ’ differs from the female parent and commercial variety Anthurium ‘ANTHUCOEN’ (U.S. Plant Pat. No. 22,630), in that ‘ANTHDINWAQ’ has a pink spathe colour, whereas ‘ANTHUCOEN’ has a purple-pink spathe colour. Additionally, the spathes of ‘ANTHUCOEN’ are oblong, whereas the spathes of ‘ANTHDINWAQ’ are round.

‘ANTHDINWAQ’ differs from the male parent ‘ANTHBESKA’ (unpatented), by having a smaller spathe, leaves and overall plant habit.

‘ANTHDINWAQ’ can also be compared to commercial variety Anthurium ‘ANTINKELES’ (U.S. Plant Pat. No. 12,115). Additional comparison data is shown in Table 1 below.
