USPP19318P2 - Gypsophila plant named ‘ESM Chispa’ - Google Patents

Abstract

A new and distinct cultivar of Gypsophila plant named ‘Esm Chispa’, characterized by its compact and mounding growth habit; uniform and freely flowering habit; small semi-double white-colored flowers; and good postproduction longevity and garden performance.

Description

Botanical designation: Gypsophila hybrida.

Cultivar denomination: ‘Esm Chispa’.

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 Chispa’.

The new Gypsophila 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 freely flowering pot-type Gypsophila cultivars.

The new Gypsophila originated from an open-pollination made by the Inventor in El Quinche, Pichincha, Ecuador in August, 2001 of a proprietary selection of Gypsophila hybrida identified as Line 34, not patented, as the female, or seed, parent with an unknown selection of Gypsophila hybrida. The cultivar Esm Chispa was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated open-pollination in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new Gypsophila by cuttings in a controlled environment in El Quinche, Pichincha, Ecuador since October, 2002, has shown that the unique features of this new Gypsophila are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Esm Chispa has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 Chispa’. These characteristics in combination distinguish ‘Esm Chispa’ as a new and distinct cultivar of Gypsophila:

• • 1. Compact and mounding growth habit.
  • 2. Uniform and freely flowering habit.
  • 3. Small semi-double white-colored flowers.
  • 4. Good postproduction longevity and garden performance.

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 were more compact than plants of the female parent selection.
  • 2. Plants of the new Gypsophila had smaller flowers than plants of the female parent selection.
  • 3. Plants of the new Gypsophila were more freely flowering than plants of the female parent selection.

Plants of the new Gypsophila can be compared to plants of the Gypsophila cultivar Dangypflash, disclosed in U.S. Plant Pat. No. 12,422. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Gypsophila differed from plants of the cultivar Dangypflash in the following characteristics:

• • 1. Plants of the new Gypsophila were more compact than plants of the cultivar Dangypflash.
  • 2. Plants of the new Gypsophila had shorter internodes than plants of the cultivar Dangypflash.
  • 3. Plants of the new Gypsophila had shorter leaves than plants of the cultivar Dangypflash.
  • 4. Plants of the new Gypsophila were more freely flowering than plants of the cultivar Dangypflash.
  • 5. Flowers of plants of the new Gypsophila were longer-lasting than plants of the cultivar Dangypflash.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in El Quinche, Pichincha, Ecuador during the winter in containers in an outdoor nursery and under conditions and 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 about five weeks after planting and were grown under long day/short day conditions. Measurements and numerical values represent averages for typical 15-week old flowering plants.
