plant named ‘AN2772113’

Abstract

A new and distinct cultivar of Anthurium plant named ‘AN2772113’, characterized by its upright to outwardly arching and uniform plant habit; freely clumping growth habit; bushy and dense plants; narrowly cordate dark green-colored leaves; freely flowering habit; inflorescences that are positioned within to slightly above the foliar plane on strong and mostly upright scapes; broadly cordate white-colored spathes and light orangish yellow-colored spadices; and durable spathes that impart good inflorescence longevity.

Description

Botanical designation: Anthurium andreanum.

Cultivar denomination: ‘AN2772113’.

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 2023/2440. 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 ‘AN2772113’.

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 Anthurium plants with attractive white-colored, durable and glossy spathes.

The new Anthurium plant originated from a cross-pollination made by the Inventor in October, 2013 in Bleiswijk, The Netherlands of a proprietary selection of Anthurium andreanum identified as code number 10-020860-0002, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 10-024661-0005, 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 May, 2016.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since August, 2018 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 ‘AN2772113’. These characteristics in combination distinguish ‘AN2772113’ as a new and distinct Anthurium plant:

• • 1. Upright to outwardly arching and uniform plant habit.
  • 2. Freely clumping growth habit; bushy and dense plants.
  • 3. Narrowly cordate dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Inflorescences that are positioned within to slightly above the foliar plane on strong and mostly upright scapes.
  • 6. Broadly cordate white-colored spathes and light orangish yellow-colored spadices.
  • 7. 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. Plants of the new Anthurium are not as freely clumping as plants of the female parent selection.
  • 2. Spathes of plants of the new Anthurium are broadly cordate in shape whereas spathes of plants of the female parent selection are broadly ovate in shape.
  • 3. Spadices of plants of the new Anthurium are not as tapering as spadices of plants of the female parent selection.

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

• • 1. Basal leaf lobes of plants of the new Anthurium are flat and separate whereas basal leaf lobes of plants of the male parent selection are incurved and close to imbricate.
  • 2. Spathes of plants of the new Anthurium are more rugose than spathes of plants of the male parent selection.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘Anthfraxk’, disclosed in U.S. Plant Pat. No. 30,921. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘Anthfraxk’ in the following characteristics:

• • 1. Basal leaf lobes of plants of the new Anthurium are flat and separate whereas basal leaf lobes of plants of ‘Anthfraxk’ are incurved and close to imbricate.
  • 2. Spathes of plants of the new Anthurium are glossier than spathes of plants of ‘Anthfraxk’.
  • 3. Spadices of plants of the new Anthurium are not as tapering as spadices of plants of ‘Anthfraxk’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 17-cm containers during the late winter 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 twelve months 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.
