Abstract

A new and distinct cultivar of Rose plant named ‘ESM R136’, characterized by its upright and strong flowering stems; moderately vigorous growth habit and high productivity; freely flowering habit; bright red-colored flowers that are typically grown as spray types; excellent postproduction longevity; and tolerance to Botrytis.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘ESM R136’.
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 R136’.
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 attractive flowers and excellent postproduction longevity.
The new Rose plant originated from a cross-pollination made by the Inventor in November, 2008 of a proprietary Rose selection identified as Line 199, not patented, as the female, or seed, parent with a proprietary Rose selection identified as Line 222, 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 September, 2009.
Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since March, 2010 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Rose have not been observed under all possible combinations of 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ESM R136’. These characteristics in combination distinguish ‘ESM R136’ as a new and distinct Rose plant:
    • 1. Upright and strong flowering stems.
    • 2. Moderately vigorous growth habit and high productivity.
    • 3. Freely flowering habit.
    • 4. Bright red-colored flowers that are typically grown as spray types.
    • 5. Excellent postproduction longevity.
    • 6. Tolerance to Botrytis.
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. Stems of plants of the new Rose have fewer thorns than stems of plants of the female parent selection.
    • 3. Flowers of plants of the new Rose have fewer petals than flowers of plants of the female parent selection.
    • 4. Plants of the new Rose and the female parent selection differ in flower color as plants of the female parent selection have velvety red-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 shorter than plants of the male parent selection.
    • 2. Stems of plants of the new Rose had more thorns than stems of the male parent selection.
    • 3. Flower buds and flowers of plants of the new Rose are slightly larger than flower buds and flowers of plants of the male parent selection.
    • 4. Flowers of plants of the new Rose have fewer petals than flowers of plants of the male parent selection.
    • 5. Plants of the new Rose and the male parent selection differ in flower color as plants of the male parent selection have orange-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Esm Fant’, disclosed in U.S. Plant Pat. No. 18,896. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of ‘Esm Fant’ in the following characteristics:
    • 1. Plants of the new Rose were more freely branching than plants of ‘Esm Fant’.
    • 2. Plants of the new Rose had longer internodes than plants of ‘Esm Fant’.
    • 3. Stems of plants of the new Rose had fewer thorns than stems of plants of ‘Esm Fant’.
    • 4. Inflorescences of plants of the new Rose had more flowers than inflorescences of plants of ‘Esm Fant’.
    • 5. Flowers of plants of the new Rose had fewer petals than flowers of plants of ‘Esm Fant’.
    • 6. Plants of the new Rose and ‘Esm Fant’ differed slightly in flower color.
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 slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.
The photographs on the left side of the sheet comprise side perspective views of typical flowering stems of ‘ESM R136’.
The photograph at the upper right of the sheet is a close-up view of a typical flower of ‘ESM R136’.
The photograph at the lower right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘ESM R136’.
 DETAILED BOTANICAL DESCRIPTION
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 hydroponic Rose production practices. Plants were pinched 13 to 14 weeks after planting and were 2.5 years old when the description and photographs were taken. During the production of the plants, day temperatures ranged from 16° C. to 30° C., night temperatures ranged from 12° C. to 16° C. and light levels ranged from 800 to 1,200 foot-candles.
