Abstract

A new and distinct cultivar of Rose plant named ‘Esm Tecno’, characterized by its strong and upright flowering stems; moderately vigorous growth habit; early flowering habit; large creamy white and yellow-colored flowers with light peach tonality; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘ESM TECNO’.
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 Tecno’.
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 February, 2002 of a proprietary Rose selection identified as code name Line 34, not patented, as the female, or seed, parent with a proprietary Rose selection identified as code name Line 10, 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 March, 2003.
Asexual reproduction of the new Rose plant by cuttings at El Quinche, Pichincha, Ecuador since November, 2004, 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 Tecno’. These characteristics in combination distinguish ‘Esm Tecno’ as a new and distinct Rose plant:
    • 1. Strong and upright flowering stems.
    • 2. Moderately vigorous growth habit.
    • 3. Early flowering habit.
    • 4. Large creamy white and yellow-colored flowers with light peach tonality.
    • 5. Good 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 have larger 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 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 taller 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 yellow-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Fenice’, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of ‘Fenice’ in the following characteristics:
    • 1. Plants of the new Rose were not as vigorous as plants of ‘Fenice’.
    • 2. Plants of the new Rose flowered earlier than plants of ‘Fenice’.
    • 3. Flowers of plants of the new Rose were more fragrant than flowers of plants of ‘Fenice’.
    • 4. Plants of the new Rose and ‘Fenice’ differed in flower color as plants of ‘Fenice’ had creamy pink-colored flowers.
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 Tecno’.
The photograph at the upper right of the sheet is a close-up view of a typical flower of ‘Esm Tecno’.
The photograph at the bottom left of the sheet is a close-up view of typical flowers of ‘Esm Tecno’.
The photographs at the center right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘Esm Tecno’.
The photograph at the lower right is a close-up view of an opening flower of ‘Esm Tecno’.
 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 four 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.
