USPP31417P2 - Anthurium plant named ‘ANTHEUYK’ - Google Patents

Abstract

A new Anthurium plant named ‘ANTHEUYK’ particularly distinguished by having shiny, weakly blistered, pink, orbicular-cordate and very durable spathes that retain the original color for a very long period of time, dark green and ovate-cordate, durable leaves, pink spadices with orange-yellow tips, early and rich flowering continuously throughout the year, and a plant height of 23.0 cm to 27.0 cm is disclosed.

Description

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHEUYK’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHEUYK’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 23.0 cm to 27.0 cm height plant with shiny and weakly blistered, pink, orbicular-cordate and very durable spathes.

The new variety originated from a cross-pollination made in September 2008 in Bleiswijk, The Netherlands. The female parent was a pink Anthurium pot plant designated ‘11376-07’ (unpatented), and the male parent was a pink Anthurium pot plant designated ‘ANTHDATAM’ (U.S. Plant Pat. No. 27,699).

A single plant was selected from the progeny of the stated cross in September 2010 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands, over a 6-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 the European Union on Nov. 25, 2016. ‘ANTHEUYK’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date 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) Shiny and weakly blistered, pink, orbicular-cordate spathes;
  • 2) Pink spadices with orange-yellow tips; and
  • 3) Green, ovate-cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, bud 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 28-week old plant grown in a greenhouse in Bleiswijk, The Netherlands, in September 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 2 shows a close-up of the mature spathe.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHEUYK’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 28-week old plants which were planted from tissue culture in 9 centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in September 2018. 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.) (2015).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

The female parent plant of ‘ANTHEUYK’, cultivar ‘11376-07’, is no longer in existence, so a meaningful comparison cannot be made.

‘ANTHEUYK’ differs from the male parent plant ‘ANTHDATAM’ (U.S. Plant Pat. No. 27,699) in that ‘ANTHEUYK’ has acute leaf apexes and spathes with an upper surface color of RHS 38A, whereas ‘ANTHDATAM’ has acuminate leaf apexes and spathes with an upper surface color of RHS 52A.

‘ANTHEUYK’ differs from similar commercial variety ‘ANTHDINWAQ’ (U.S. Plant Pat. No. 26,048) in that ‘ANTHEUYK’ has acute leaf apexes and spathes with an upper surface color of RHS 38A, whereas ‘ANTHDINWAQ’ has acuminate leaf apexes and spathes with an upper surface color of RHS 51A. Additionally, ‘ANTHEUYK’ has a longer plant height than ‘ANTHDINWAQ’.

‘ANTHEUYK’ differs from similar commercial variety ‘ANTHEOCMA’ (unpatented) in that ‘ANTHEUYK’ has ovate-cordate leaves and orbicular-cordate spathes with an upper surface color of RHS 38A, whereas ‘ANTHEOCMA’ has elliptical-cordate leaves and ovate spathes with an upper surface color of RHS 38D.
