Gypsophila plant named ‘Esm Cirque’

Abstract

A new and distinct cultivar of Gypsophila plant named ‘Esm Cirque’, characterized by its erect and strong flowering stems; early, uniform and freely flowering habit; double luminous white-colored flowers; and good postproduction longevity.

Description

Botanical designation: Gypsophila hybrida.

Cultivar denomination: ‘Esm Cirque’.

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 Cirque’.

The new Gyposphila 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 Gyposphila cultivars with many petals per flower and straight stems.

The new Gypsophila originated from a cross-pollination made by the Inventor in El Quinche, Pichincha, Ecuador in August, 2003 of a proprietary selection of Gypsophila hybrida identified as Line 114, not patented, as the female, or seed, parent with a proprietary selection of Gypsophila hybrida identified as Line 56, not patented. The cultivar Esm Cirque was discovered and selected by the Inventor as a flowering plant from within the progeny of the state cross-pollination in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new Gyposphila by cuttings in a controlled environment in El Quinche, Pichincha, Ecuador since August, 2004, 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 Cirque 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 Cirque’. These characteristics in combination distinguish ‘Esm Cirque’ as a new and distinct cultivar of Gypsophila:

• • 1. Erect and strong flowering stems.
  • 2. Early, uniform and freely flowering habit.
  • 3. Double 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 flowered earlier than plants of the female parent selection.
  • 2. Plants of the new Gypsophila had larger flowers than plants of the female parent selection.
  • 3. Flowers of plants of the new Gypsophila had more petals than flowers of plants of the female parent selection.

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 had stronger flowering stems than plants of the male parent selection.
  • 2. Plants of the new Gypsophila had smaller flowers than plants of the male parent selection.

Plants of the new Gypsophila can be compared to plants of the Gypsophila cultivar New Hope, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Gypsophila differed from plants of the cultivar New Hope in the following characteristics:

• • 1. Plants of the new Gypsophila had shorter internodes than plants of the cultivar New Hope.
  • 2. Plants of the new Gypsophila had shorter, but broader leaves than plants of the cultivar New Hope.
  • 3. Plants of the new Gypsophila flowered earlier and more freely than plants of the cultivar New Hope.
  • 4. Plants of the new Gypsophila did not produce seeds and fruits whereas plants of the cultivar New Hope produced seeds and fruits.

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 during the winter in El Quinche, Pichincha, Ecuador in ground beds 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 four-month old flowering plants.
