Abstract

A new and distinct cultivar of Gerbera plant named ‘GLOLIP21AA’, characterized by its compact, broadly upright and uniformly mounding plant habit; moderately vigorous growth habit; dense and bushy appearance; numerous inflorescences with pink-colored ray florets; upright and moderately strong peduncles; good garden performance and relative tolerance to low temperatures.

Description

Botanical designation: Gerbera hybrida.

Cultivar denomination: ‘GLOLIP21AA’.

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 ‘GLOLIP21AA’.

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 compact garden Gerbera plants with numerous attractive inflorescences, resistant to cold temperatures and good garden performance.

The new Gerbera plant originated from a cross-pollination during the spring of 2015 of a proprietary selection of Gerbera hybrida identified as code number 47180, not patented, as the female, or seed, parent with a proprietary selection of Gerbera hybrida identified as code number 47275, 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 during the summer of 2016 in De Kwakel, The Netherlands.

Asexual reproduction of the new Gerbera plant by vegetative terminal cuttings and in vitro meristem culture since the autumn of 2016 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 ‘GLOLIP21AA’. These characteristics in combination distinguish ‘GLOLIP21AA’ as a new and distinct Gerbera plant:

- 1. Compact, broadly upright and uniformly mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Dense and bushy appearance.
- 4. Numerous inflorescences with 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 larger inflorescences than plants of the female parent selection.
- 2. Plants of the new Gerbera have pink-colored ray florets whereas plants of the female parent selection have white-colored ray florets.

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 shorter and narrower leaves than plants of the male parent selection.
- 2. Plants of the new Gerbera have lighter pink-colored ray florets than plants of the male parent selection.

Plants of the new Gerbera can be compared to plants of the Gerbera hybrida ‘MAJLIP20AA’, disclosed in a U.S. Plant patent application Ser. No. 17/747,743 filed concurrently. In side-by-side comparisons, plants of the new Gerbera differ from plants of ‘MAJLIP20AA’ in the following characteristics:

- 1. Plants of the new Gerbera are not as vigorous as plants of ‘MAJLIP20AA’.
- 2. Plants of the new Gerbera have larger leaves than plants of ‘MAJLIP20AA’.
- 3. Plants of the new Gerbera have larger inflorescences than plants of ‘MAJLIP20AA’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gerbera plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gerbera plant.

The photograph is a side perspective view of a typical flowering plant of ‘GLOLIP21AA’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the winter and early spring in 17-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial garden Gerbera production. During the production of the plants, day and night temperatures ranged from 12° C. to 15° C. Plants were six months old when the photograph was taken and 20 weeks old when the description was 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.
