Abstract

A new and distinct cultivar of Rose plant named ‘Esm Pacarina’, characterized by its long, moderately strong and upright flowering stems; durable foliage; yellow orange-colored flowers with orange and orange red-colored margins; good postproduction longevity; and resistance to Botrytis.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘ESM PACARINA’.
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 Pacarina’.
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, 2000 of a proprietary Rose selection identified as code name Line 53, not patented, as the female, or seed, parent with a proprietary Rose selection identified as code name Line 50, 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, 2001.
Asexual reproduction of the new Rose plant by cuttings at El Quinche, Pichincha, Ecuador since April, 2001, 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 Pacarina’. These characteristics in combination distinguish ‘Esm Pacarina’ as a new and distinct Rose plant:
    • 1. Long, moderately strong and upright flowering stems.
    • 2. Durable foliage.
    • 3. Yellow orange-colored flowers with orange and orange red-colored margins.
    • 4. Good postproduction longevity.
    • 5. 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 dark pink and red bi-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 freely flowering than plants of the male parent selection.
    • 2. Plants of the new Rose have slightly smaller 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 salmon pink-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Korlumara’, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of ‘Korlumara’ in the following characteristics:
    • 1. Plants of the new Rose were not as vigorous as plants of ‘Korlumara’.
    • 2. Plants of the new Rose had smaller leaves than plants of ‘Korlumara’.
    • 3. Plants of the new Rose had slightly smaller flowers than plants of ‘Korlumara’.
    • 4. Plants of the new Rose had fewer petals per flower than plants of ‘Korlumara’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 Pacarina’.
The photograph at the upper right of the sheet is a top perspective close-up view of a typical flower of ‘Esm Pacarina’.
The photograph at the center of the sheet is a close-up view of the upper and lower surfaces of typical petals of ‘Esm Pacarina’.
The photographs at the lower right of the sheet are close-up views of the upper and lower surfaces of typical leaves of ‘Esm Pacarina’.
 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 ground beds in a polyethylene-covered greenhouse in El Quinche, Pichincha, Ecuador and under commercial Rose production practices. Plants were pinched about 13 to 14 weeks after planting. Plants were three 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.
