Abstract

A new and distinct cultivar of Rose plant named ‘Esm Guinda’, characterized by its long, strong and upright flowering stems; durable foliage; red-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Rosa hybrida. Cultivar denomination: ‘Esm Guinda’.
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 Guinda’.
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 September, 2004 of a proprietary Rose selection identified as code number 108, not patented, as the female, or seed, parent with a proprietary Rose selection identified as code number 129, 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, 2005.
Asexual reproduction of the new Rose plant by cuttings at El Quinche, Pichincha, Ecuador since July, 2005, 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
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Esm Guinda’ . These characteristics in combination distinguish ‘Esm Guinda’ as a new and distinct cultivar:
    • 1. Long, strong and upright flowering stems.
    • 2. Durable foliage.
    • 3. Red-colored flowers.
    • 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 have fewer thorns than plants of the female parent selection.
    • 2. Plants of the new Rose have smaller flowers than plants of female parent selection.
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 are more freely flowering than plants of the male parent selection.
    • 3. Plants of the new Rose have larger flowers than plants of male parent selection.
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 following characteristics:
    • 1. Plants of the new Rose were more vigorous and had stronger stems than plants of ‘Freedom’.
    • 2. Plants of the new Rose had smaller leaves and leaflets than plants of ‘Freedom’.
    • 3. Plants of the new Rose flowered earlier and more freely than plants of ‘Freedom’.
    • 4. Plants of the new Rose had fewer petals per flower than 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 slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose.
The photograph at the upper left of the sheet comprises a side perspective view of a typical flowering stem of ‘Esm Guinda’.
The photograph at the lower left of the sheet is a close-up view of typical flowers of ‘Esm Guinda’.
The photographs at the top right of the sheet is a close-up view of a typical flower and the upper and lower surfaces of typical petals of ‘Esm Guinda’.
The photographs at the lower right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘Esm Guinda’.
 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 El Quinche, Pichincha, Ecuador, in a polyethylene-covered greenhouse and under commercial production practices. Plants were pinched about 13.5 weeks after planting. Plants were about 30 months old when the photographs and description were taken. During the production of the plants, day temperatures ranged from about 16° C. to 30° C., night temperatures ranged from about 12° C. to 16° C. and light levels ranged from about 800 to 1,200 foot-candles.
