plant named ‘Esm G007’

Abstract

A new and distinct cultivar of Gypsophila plant name ‘Esm G007’, characterized by its erect, straight and moderately strong flowering stems; uniform and freely flowering habit; compact and dense inflorescences with luminous white-colored flowers; and good postproduction longevity.

Description

Botanical designation: Gypsophila paniculata×Gypsophila porrigens.

Cultivar denomination: ‘ESM G007’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gypsophila plant, botanically known as Gypsophila paniculata×Gypsophila porrigens, grown commercially as a cut flower, and hereinafter referred to by the name ‘Esm G007’.

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 Gypsophila plants with numerous flowers and good postproduction longevity.

The new Gypsophila plant originated from a cross-pollination conducted by the Inventor in El Quinche, Pichincha, Ecuador in August, 2007 of a proprietary selection of Gypsophila paniculata identified as Line 252, not patented, as the female, or seed, parent with a proprietary selection of Gypsophila porrigens identified as Line 337, 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 February, 2008.

Asexual reproduction of the new Gypsophila plant by cuttings in a controlled environment in El Quinche, Pichincha, Ecuador since April, 2008 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 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 G007’. These characteristics in combination distinguish ‘Esm G007’ as a new and distinct Gypsophila plant:

• • 1. Erect, straight and moderately strong flowering stems.
  • 2. Uniform and freely flowering habit.
  • 3. Compact and dense inflorescences with luminous white-colored flowers.
  • 4. Good postproduction longevity.

In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Gypsophila differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Gypsophila had moderately strong flowering stems whereas plants of the female parent selection had strong flowering stems.
  • 2. Flower form of plants of the new Gypsophila was semi-double whereas flower form of plants of the female parent selection was double.

In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Gypsophila differed from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Gypsophila were taller than plants of the male parent selection.
  • 2. Plants of the new Gypsophila had denser inflorescences than plants of the male parent selection.
  • 3. Flowers of plants of the new Gypsophila had more petals than flowers of plants of the male parent selection.
  • 4. Flower color of plants of the new Gypsophila was more luminous than flower color of plants of the male parent selection.

Plants of the new Gypsophila can also be compared to plants of the Gypsophila ‘Esmamerica’, disclosed in U.S. Plant Pat. No. 14,940. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Gypsophila differed from plants of ‘Esmamerica’ in the following characteristics:

• • 1. Plants of the new Gypsophila were shorter and broader than plants of ‘Esmamerica’.
  • 2. Plants of the new Gypsophila were not as vigorous as plants of ‘Esmamerica’.
  • 3. Inflorescences of plants of the new Gypsophila were larger and denser than inflorescences of plants of ‘Esmamerica’.
  • 4. Plants of new Gypsophila were more freely flowering than plants of ‘Esmamerica’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gypsophila 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 Gypsophila plant. The photograph comprises a side perspective view of a typical flowering stem of ‘Esm G007’ (upper left); close-up view of a typical inflorescence of ‘Esm G007’ (upper right); close-up view of a typical flower of ‘Esm G007’ (lower left); and close-up view of upper and lower surfaces of typical leaves of ‘Esm G007’ (lower right).

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 and under cultural practices which approximate those generally used in commercial cut Gypsophila production. During the production of the plants, day temperatures ranged from 11° C. to 28° C. and night temperatures ranged from 5° C. to 11° C. Plants were pinched one time five weeks after planting and five weeks after pinching, plants were grown under long day/short day conditions. Measurements and numerical values represent averages for typical 44-week old flowering plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fourth Edition, 2001, except where general terms of ordinary dictionary significance are used.
