Abstract: A new and distinct cultivar of Rose plant named `Esm R068`, characterized by its upright, long and strong flowering stems; vigorous growth habit and high productivity; red-colored flowers that are typically grown as single stems; and excellent postproduction longevity.
Claim: It is claimed:

1. A new and distinct Rose plant named `Esm R068` as illustrated and described.
Description: Botanical designation: Rosahybrida.

Cultivar denomination: `ESM R068`.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as a cut flower Rose plant, and hereinafter referred to by the name `Esm R068`.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program was to develop new cut flower Rose varieties with red-colored flowers and excellentpostproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor in May, 2007 of a proprietary Rose selection identified as Line 17, not patented, as the female, or seed, parent with a proprietary Rose selection identified as Line299, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in El Quinche,Pichincha, Ecuador in April, 2008.

Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since July, 2008 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

Plants of the new Rose 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 and light intensity, withouthowever, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Esm R068`. These characteristics in combination distinguish `Esm R068` as a new and distinct Rose plant: 1. Upright, long and strongflowering stems. 2. Vigorous growth habit and high productivity. 3. Red-colored flowers that are typically grown as single stems. 4. Excellent postproduction longevity.

Plants of the new Rose differ from plants of the female parent selection in the following characteristics: 1. Plants of the new Rose are taller than plants of female parent selection. 2. Plants of the new Rose are more productive than plantsof female parent selection. 3. Flowering stems of plants of the new Rose have fewer thorns than flowering stems of plants of the female parent selection. 4. Plants of the new Rose have larger flowers than plants of the female parent selection. 5. Plants of the new Rose and the female parent selection differ in flower color as plants of the female parent selection have orange and pink bi-colored flowers.

Plants of the new Rose differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Rose are more productive than plants of the male parent selection. 2. Plants of the new Rose and the male parentselection differ in flower color as plants of the male parent selection have red and lighter red bi-colored flowers.

Plants of the new Rose can be compared to plants of Rose `Freedom`, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of `Freedom` in the followingcharacteristics: 1. Plants of the new Rose were more vigorous than plants of `Freedom`. 2. Plants of the new Rose were broader than plants of `Freedom`. 3. Plants of the new Rose had shorter internodes than plants of `Freedom`. 4. Plants of thenew Rose had stronger flowering stems than plants of `Freedom`. 5. Plants of the new Rose and `Freedom` differed in stem color as plants of `Freedom` had green-colored stems. 6. Plants of the new Rose flowered earlier than plants of `Freedom`. 7. Flowers of plants of the new Rose were larger with fewer petals than flowers of plants of `Freedom`. 8. Flowers of plants of the new Rose were longer lasting than flowers of plants of `Freedom`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.

The photograph at the left of the sheet comprises a side perspective view of typical flowering stem of `Esm R068`.

The photograph at the upper right of the sheet is a close-up view of a typical flower of `Esm R068`.

The photographs at the bottom right of the sheet are close-up views of the upper and lower surfaces of typical leaves of `Esm R068`.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose 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 and light intensity, without,however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown in 10-liter containers in a polyethylene-covered greenhouse in El Quinche, Pichincha, Ecuador and under typical hydroponicRose production practices. Plants were pinched about 13 to 14 weeks after planting. Plants were 61 weeks old when the photographs and detailed description were taken. During the production of the plants, day temperatures ranged from 16.degree. C. to30.degree. C., night temperatures ranged from 12.degree. C. to 16.degree. C. and light levels ranged from 800 to 1,200 foot-candles.
