Abstract

A new and distinct cultivar of Rose plant named ‘Esm R001’, characterized by its strong and upright flowering stems; vigorous growth habit; durable leaves; large intense yellow-colored flowers; good postproduction longevity; and resistance to Botrytis.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘ESM R001’.
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 R001’.
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 freely-flowering cut flower Rose varieties with novel and attractive flower colors and excellent postproduction longevity.
The new Rose plant originated from a cross-pollination made by the Inventor in March, 2005 of a proprietary Rose selection identified as code name Line 13, not patented, as the female, or seed, parent with a proprietary Rose selection identified as code name Line 183, 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 January, 2006.
Asexual reproduction of the new Rose plant by cuttings at El Quinche, Pichincha, Ecuador since October, 2006, 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 environmental conditions. The phenotype may vary somewhat with variations in environment 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 R001’. These characteristics in combination distinguish ‘Esm R001’ as a new and distinct Rose plant:
    • 1. Strong and upright flowering stems.
    • 2. Vigorous growth habit.
    • 3. Durable leaves.
    • 4. Large intense yellow-colored flowers.
    • 5. Good postproduction longevity.
    • 6. Resistant 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 smaller than plants of female parent selection.
    • 2. Plants of the new Rose have smaller flowers than plants of the female parent selection.
    • 3. Plants of the new Rose and the female parent selection differ in flower color as plants of the female parent selection have light yellow-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 taller than plants of the male parent selection.
    • 2. Plants of the new Rose have larger flowers than plants of the male parent selection.
    • 3. Plants of the new Rose and the male parent selection differ in flower color as plants of the male parent selection have light yellow-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Golden Gate’, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of ‘Golden Gate’ in the following characteristics:
    • 1. Plants of the new Rose were more vigorous and larger than plants of ‘Golden Gate’.
    • 2. Plants of the new Rose had thicker and stronger stems than plants of ‘Golden Gate’.
    • 3. Plants of the new Rose had larger leaves than plants of ‘Golden Gate’.
    • 4. Plants of the new Rose had larger flowers than plants of ‘Golden Gate’.
    • 5. Flowers of plants of the new Rose were longer lasting than flowers of plants of ‘Golden Gate’.
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 photograph at the left of the sheet comprises a side perspective view of a typical flowering stem of ‘Esm R001’.
The photograph at the upper right of the sheet is a close-up view of a typical flower of ‘Esm R001’.
The photograph at the bottom left of the sheet is a close-up view of typical flowers of ‘Esm R001’.
The photographs at the lower right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘Esm R001’.
 DETAILED BOTANICAL DESCRIPTION
Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown in 10-cm containers in a polyethylene-covered greenhouse in El Quinche, Pichincha, Ecuador and under typical hydroponic Rose production practices. Plants were pinched about 13 to 14 weeks after planting. Plants were 2.5 years old when the photographs and description 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.
