Abstract

A new Anthurium plant particularly distinguished by having big, bright-red, symmetricly round, durable spathes that slowly turn brown-red with age, green, durable leaves, moderate shoot formation, flowers early and continuously throughout the year, a compact plant habit and a plant height of 35 cm to 40 cm, is disclosed.

Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘Antholodoj’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the cultivar name ‘Antholodoj’. The new cultivar originated from a hybridization made in 2000 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant ‘Anthbnzl’ (U.S. Plant Pat. No. 17,134), while the male parent was a red Anthurium pot plant ‘Anthepedi’ (U.S. Plant Pat. No. 18,644).

The new cultivar was selected in 2002 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 cultivar were applied with the European Union on Jan. 26, 2007. ‘Antholodoj’ not been made publicly available 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 cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands.

• • 1) Bright-red symmetricly round spathes;
  • 2) Green, large durable leaves that are positioned diagonal to vertical;
  • 3) Inflorescence grows just above the foliage;
  • 4) Moderate shoot formation;
  • 5) Compact plant habit;
  • 6) Flowers early and rich and continuously throughout the year; and
  • 7) Is a type of pot plant with a plant height of 35 cm to 40 cm.

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 2007.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Antholodoj’. 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 17-cm pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November of 2007. 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 CULTIVARS

‘Antholodoj’ differs from the female parent ‘Anthbnzl’ (U.S. Plant Pat. No. 17,134), by having less cupped leaves, less shoots, a longer spadix touching spathe lobes, more symmetric spathes and a smaller angle between the spathe and spadix than ‘Anthbnzl’.

‘Antholodoj’ differs from the male parent and commercial variety ‘Anthepedi’ (U.S. Plant Pat. No. 18,644), by having a smaller spathe and a shorter spadix than ‘Anthepedi’. See Table 1 below.
