Description

Botanical designation: Anthurium andreanum.

Cultivar denomination: ‘AN2973182’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR AND APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Anthura B. V. of Bleiswijk, The Netherlands on Nov. 22, 2023, application number 2023/2443. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum and hereinafter referred to by the name ‘AN2973182’.

The new Anthurium plant is a product of a controlled breeding program conducted by the Inventor in Bleiswijk, The Netherlands. The objective of the breeding program is to create new freely-clumping cut flower Anthurium plants with attractive red-colored, durable and glossy spathes.

The new Anthurium plant originated from a cross-pollination made by the Inventor in August 2001 in Bleiswijk, The Netherlands of a proprietary selection of Anthurium andreanum identified as code number 00-002340-0006, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 01-003366-0001, not patented, as the male, or pollen, parent. The new Anthurium was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bleiswijk, The Netherlands in October 2004.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since January 2009 has shown that the unique features of this new Anthurium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Anthurium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AN2973182’. These characteristics in combination distinguish ‘AN2973182’ as a new and distinct cut flower Anthurium plant:

    • 1. Upright to outwardly arching plant habit.
    • 2. Narrowly cordate dark green-colored leaves.
    • 3. Large inflorescences that are positioned within to slightly above the foliar plane on strong and slightly outwardly scapes.
    • 4. Inflorescences with two spathes.
    • 5. Glossy and rugose red-colored spathes and lighter red-colored spadices.
    • 6. Durable spathes that impart good inflorescence longevity.

Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Spathes of plants of the new Anthurium are more rugose than spathes of plants of the female parent selection.
    • 2. Spathes of plants of the new Anthurium are red in color whereas spathes of plants of the female parent selection are pink in color.

Plants of the new Anthurium differ primarily from plants of the male parent selection in the following characteristics:

    • 1. Spathes of plants of the new Anthurium are not as large as spathes of plants of the male parent selection.
    • 2. Spathes of plants of the new Anthurium are broadly cordate in shape whereas spathes of plants of the male parent selection are close to rotund in shape.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘Anthilci’, not patented. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘Anthilci’ in the following characteristics:

    • 1. Spathes of plants of the new Anthurium are more rugose than spathes of plants of ‘Anthilci’.
    • 2. Spadices of plants of the new Anthurium are light red in color whereas spadices of plants of ‘Anthilci’ are green and white in color.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in ground beds during the summer in a glass-covered greenhouse in Bleiswijk, The Netherlands. Plants were grown under conditions and practices which approximate those generally used in commercial Anthurium production. During the production of the plants, day and night temperatures ranged from about 19° C. to 22.5° C. and light levels ranged from 100 μmol to 200 μmol. Plants were 6.5 years old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
