USPP34430P2 - Anthurium plant named ‘ANTHGNOBIC’ - Google Patents

Abstract

A new Anthurium plant named ‘ANTHGNOBIC’ particularly distinguished by having very weakly blistered and medium glossy, concave, red with white venation, cordate, and durable spathes that retain the original color for a very long period of time with dark green, deltoid, durable leaves, creamy white spadices with pink shade and orange tips, early and rich flowering continuously throughout the year, and a plant height of 22.0 cm to 26.0 cm is disclosed.

Description

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHGNOBIC’.

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 ‘ANTHGNOBIC’. 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 plant with a height of 22.0 cm to 26.0 cm having very weakly blistered and medium glossy, concave, red with white venation, cordate, and durable spathes.

The new variety originated from a cross-pollination made in February 2011 in Bleiswijk, the Netherlands. The female parent was a pink Anthurium pot plant designated ‘18574-04’ (unpatented), and the male parent was a pink Anthurium pot plant designated ‘18397-02’ (unpatented).

A single plant was selected from the progeny of the stated cross in March 2013. Asexual reproduction of the new variety by tissue culture in 2015 in Bleiswijk, the Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Community Plant Variety Rights for this variety have been applied for in the European Union on Nov. 27, 2017 (Application no. 2017/3100), by Applicant who obtained the subject matter disclosed directly from the inventor. ‘ANTHGNOBIC’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application with the exception of sales or disclosures made one year or less before the effective filing date of this claimed invention by Applicant who obtained ‘ANTHGNOBIC’ directly from the inventor.

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) Very weakly blistered and medium glossy, concave, red with white venation, cordate spathes;
  • 2) Creamy white colored spadices with pink shade and orange tips;
  • 3) Green, deltoid leaves; and
  • 4) Angle of the distal part of the spathe to the peduncle is acute.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms 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 December 2021. 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. 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 ‘ANTHGNOBIC’. 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 December 2021. 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 (RHS) (2015).
