BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gypsophila plant, botanically known as Gypsophila hybrida, grown commercially as a cut flower, and hereinafter referred to by the name ‘ESM G057’.

The new Gypsophila plant is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program is to create new productive and uniform Gypsophila plants with numerous large double flowers and good postproduction longevity.

The new Gypsophila plant originated from a cross-pollination conducted by the Inventor in El Quinche, Pichincha, Ecuador in November 2010 of a proprietary selection of Gypsophila hybrida identified as line 251, not patented, as the female, or seed, parent with a proprietary selection of Gypsophila hybrida identified as line 210, not patented, as the male, or pollen, parent. The new Gypsophila plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in El Quinche, Pichincha, Ecuador in March 2016.

Asexual reproduction of the new Gypsophila plant by cuttings in a controlled environment in El Quinche, Pichincha, Ecuador since June 2017 has shown that the unique features of this new Gypsophila plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gypsophila 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, daylength 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 ‘ESM G057’. These characteristics in combination distinguish ‘ESM G057’ as a new and distinct Gypsophila plant:

• • 1. Strong flowering stems.
  • 2. Uniform and freely flowering habit.
  • 3. Large and dense inflorescences with large double white-colored flowers.
  • 4. Relatively high cut flower yield.
  • 5. Good postproduction longevity.

In side-by-side comparisons, plants of the new Gypsophila differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Gypsophila have denser inflorescences than plants of the female parent selection.
  • 2. Flowers of plants of the new Gypsophila are double-types whereas flowers of plants of the female parent selection are semi-double-types.
  • 3. Flowers of plants of the new Gypsophila have more petals and petaloids than flowers of plants of the female parent selection.

In side-by-side comparisons, plants of the new Gypsophila differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Gypsophila are more vigorous and denser than plants of the male parent selection.
  • 2. Stems and flowering stems of plants of the new Gypsophila are sturdier than and not as flexible as stems and flowering stems of the male parent selection.
  • 3. Plants of the new Gypsophila flower about four to six weeks earlier than plants of the male parent selection.
  • 4. Flowers of plants of the new Gypsophila are double-types whereas flowers of plants of the male parent selection are semi-double-types.

Plants of the new Gypsophila can also be compared to plants of Gypsophila hybrida ‘Esm Alicia’, disclosed in U.S. Plant Pat. No. 19,479. In side-by-side comparisons, plants of the new Gypsophila differ from plants of ‘Esm Alicia’ in the following characteristics:

• • 1. Plants of the new Gypsophila flower two weeks later than plants of ‘Esm Alicia’.
  • 2. Flowers of plants of the new Gypsophila are double-types whereas flowers of plants of ‘Esm Alicia’ are semi-double-types.
  • 3. Flowers of plants of the new Gypsophila have more petals and petaloids than flowers of plants of ‘Esm Alicia’.

Plants of the new Gypsophila can also be compared to plants of Gypsophila hybrida ‘ESM G052’, disclosed in a U.S. Plant patent application Ser. No. 18/981,530 filed concurrently. In side-by-side comparisons, plants of the new Gypsophila differ from plants of ‘ESM G052’ in the following characteristics:

• • 1. Plants of the new Gypsophila are not as vigorous as plants of ‘ESM G052’.
  • 2. Plants of the new Gypsophila flower about one week earlier than plants of ‘ESM G052’.
  • 3. Inflorescences of plants of the new Gypsophila have more flowers than inflorescences of plants of ‘ESM G052’.
  • 4. Flowers of plants of the new Gypsophila have more petals/petaloids than flowers of plants of ‘ESM G052’.
  • 5. Plants of the new Gypsophila yield more flowering stems per plant as plants of ‘ESM G052’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in ground beds in an outdoor nursery in El Quinche, Pichincha, Ecuador in March and under cultural practices which approximate those generally used in commercial cut Gypsophila production. During the production of the plants, day temperatures ranged from 14° C. to 21° C., night temperatures ranged from 6° C. to 9° C. and light levels averaged 19.3 klux. Plants were pinched one time three weeks after planting and were 16 weeks old when the photographs and the detailed description were taken.
