plant named ‘GOS202108’

Abstract

A new and distinct cultivar of Gerbera plant named ‘GOS202108’, characterized by its broadly upright and uniformly mounding plant habit; vigorous growth habit and moderate to rapid growth rate; dense and bushy appearance; numerous double type inflorescences with pale purplish pink-colored ray florets; upright and moderately strong peduncles; and good garden performance and relative tolerance to low temperatures.

Description

Botanical designation: Gerbera hybrida.

Cultivar denomination: ‘GOS202108’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant, botanically known as Gerbera hybrida and hereinafter referred to by the cultivar name ‘GOS202108’.

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new garden Gerbera plants with numerous and attractive inflorescences, resistance to low temperatures and good garden performance.

The new Gerbera plant originated from a cross-pollination in September 2020 of a proprietary selection of Gerbera hybrida identified as code number GO 1718, not patented, as the female, or seed, parent with a proprietary selection of Gerbera hybrida identified as code number GO 1433, not patented, as the male, or pollen, parent. The new Gerbera plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in August 2021.

Asexual reproduction of the new Gerbera plant by vegetative terminal cuttings since February 2022 in a controlled environment in De Kwakel, The Netherlands, has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental 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 ‘GOS202108’. These characteristics in combination distinguish ‘GOS202108’ as a new and distinct Gerbera plant:

• • 1. Broadly upright and uniformly mounding plant habit.
  • 2. Vigorous growth habit and moderate to rapid growth rate.
  • 3. Dense and bushy appearance.
  • 4. Numerous double type inflorescences with pale purplish pink-colored ray florets.
  • 5. Upright and moderately strong peduncles.
  • 6. Good garden performance and relative tolerance to low temperatures.

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

• • 1. Plants of the new Gerbera have smaller inflorescences than plants of the female parent selection.
  • 2. Plants of the new Gerbera have smaller ray florets than plants of the female parent selection.

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

• • 1. Plants of the new Gerbera have narrower leaves than plants of the male parent selection.
  • 2. Inflorescences of plants of the new Gerbera are double types whereas inflorescences of plants of the male parent selection are semi-double types.

Plants of the new Gerbera can be compared to plants of the Gerbera hybrida ‘Garsurprise’, disclosed in U.S. Plant Pat. No. 27,962. In side-by-side comparisons, plants of the new Gerbera differ from plants of ‘Garsurprise’ in the following characteristics:

• • 1. Plants of the new Gerbera have larger inflorescences than plants of ‘Garsurprise’.
  • 2. Inflorescences of plants of the new Gerbera are double types whereas inflorescences of plants of ‘Garsurprise’ are single types.
  • 3. Ray florets of plants of the new Gerbera are pale purplish pink in color whereas ray florets of plants of ‘Garsurprise’ are dark red purple in color.
