Abstract: A new and distinct cultivar of Gypsophila plant named `Esm Rena`, characterized by its erect and strong flowering stems; early, uniform and freely flowering habit; large luminous white-colored flowers with numerous petals and petaloids; and good postproduction longevity.
Claim: It is claimed:

1. A new and distinct Gypsophila plant named `Esm Rena` as illustrated and described.
Description: Botanical designation:Gypsophila hybrida.

Cultivar denomination: `ESM RENA`.

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 Rena`.

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 Gypsophila cultivars with many petals per flowerand 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 148, not patented, as the female, or seed, parentwith a proprietary selection of Gypsophila hybrida identified as Line 31, not patented, as the male, or pollen, parent. The cultivar Esm Rena was discovered and selected by the Inventor as a flowering plant from within the progeny of the statedcross-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 June, 2004, has shown that the unique features of this new Gypsophila are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The cultivar Esm Rena 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 ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Esm Rena`. These characteristics in combination distinguish `Esm Rena` as a new and distinct cultivar of Gypsophila: 1. Erect and strongflowering stems. 2. Early, uniform and freely flowering habit. 3. Large luminous white-colored flowers with numerous petals and petaloids. 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 stronger floweringstems than plants of the female parent selection. 2. Plants of the new Gypsophila had larger flowers than 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 were taller than plants ofthe male parent selection. 2. Plants of the new Gypsophila were more freely flowering than plants of the male parent selection. 3. Plants of the new Gypsophila had stronger peduncles than plants of the male parent selection.

Plants of the new Gypsophila can also 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 Gypsophiladiffered from plants of the cultivar Dangypflash in the following characteristics: 1. Plants of the new Gypsophila were taller and more narrow than plants of the cultivar Dangypflash. 2. Plants of the new Gypsophila had shorter internodes than plantsof the cultivar Dangypflash. 3. Plants of the new Gypsophila had shorter leaves than plants of the cultivar Dangypflash.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Gypsophila. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gypsophila.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of `Esm Rena`.

The photograph on the second sheet is a close-up view of typical flowers of `Esm Rena`.

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 describeplants grown in El Quinche, Pichincha, Ecuador during the winter 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.degree. C. to 28.degree. C. and night temperatures ranged from 5.degree. C. to 11.degree. 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 six-month old flowering plants. Botanical classification: Gypsophila hybrida cultivar Esm Rena.
