Abstract
A new and distinct cultivar of Rose plant named ‘ESM R031’, characterized by its upright, long and strong flowering stems; vigorous growth habit and high productivity; relatively large red-colored flowers that are typically grown as spray types; excellent postproduction longevity; and relative tolerance to Powdery Mildew.
Description
Botanical designation: Rosa hybrida.
Cultivar denomination: ‘ESM R031’.
The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, which is commercially produced as a cut flower Rose plant and hereinafter referred to by the name ‘ESM R031’.
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 unique and attractive flowers 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 Line 90, not patented, as the female, or seed, parent with a proprietary Rose selection identified as Line 42, 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 November, 2006.
Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since February, 2007 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.
Plants of the new Rose have not been observed under all possible environmental conditions and cultural practices. The phenotype of the new Rose plant 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 R031’. These characteristics in combination distinguish ‘ESM R031’ as a new and distinct Rose plant:
-
- 1. Upright, long and strong flowering stems.
- 2. Vigorous growth habit and high productivity.
- 3. Relatively large red-colored flowers that are typically grown as spray types.
- 4. Excellent postproduction longevity.
- 5. Relative tolerance to Powdery Mildew.
Plants of the new Rose differ from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Rose are more vigorous and larger than plants of female parent selection.
- 2. Plants of the new Rose have larger flowers than plants of 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 pink-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 vigorous and larger than plants of the male parent selection.
- 2. Plants of the new Rose and the male parent selection differ in flower color as plants of the male parent selection have darker red-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Babe’, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of ‘Babe’ in the following characteristics:
-
- 1. Plants of the new Rose were more vigorous and larger than plants of ‘Babe’.
- 2. Plants of the new Rose had shorter internodes than plants of ‘Babe’.
- 3. Plants of the new Rose had larger leaflets than plants of ‘Babe’.
- 4. Plants of the new Rose flowered later than plants of ‘Babe’.
- 5. Plants of the new Rose had larger sprays with more flowers per spray than plants of ‘Babe’.
- 6. Plants of the new Rose had larger flowers than plants of ‘Babe’.
- 7. Plants of the new Rose and ‘Babe’ differed in flower color as plants of ‘Babe’ had light orange-colored flowers.
- 8. Plants of the new Rose had shorter peduncles than plants of ‘Babe’.
- 9. Plants of the new Rose are more tolerant to Powdery Mildew than plants of ‘Babe’.
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 typical flowering stem of ‘ESM R031’.
The photograph at the lower left is a close-up view of a typical flower of ‘ESM R031’.
The photograph at the upper right is a close-up view of a typical spray of flowers of ‘ESM R031’.
The photographs at the bottom right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘ESM R031’.
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 about 13 to 14 weeks after planting. Plants were 3.5 years old when the photographs and detailed 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.
