Rose plant named ‘Esm Alandaluz’

Abstract

A new and distinct cultivar of Rose plant named ‘Esm Alandaluz’, characterized by its long and upright flowering stems; uniform and freely flowering habit; salmon-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘ESM ALANDALUZ’.

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, and hereinafter referred to by the name ‘Esm Alandaluz’.

The new Rose 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 cultivar originated from a cross-pollination made by the Inventor in February, 2002 of a proprietary Rose selection identified as code number 90, not patented, as the female, or seed, parent with a proprietary Rose selection identified as code number 91, not patented, as the male, or pollen, parent. The cultivar Esm Alandaluz was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new Rose by cuttings at El Quinche, Pichincha, Ecuador since August, 2003, has shown that the unique features of this new Rose 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 Alandaluz’. These characteristics in combination distinguish ‘Esm Alandaluz’ as a new and distinct cultivar:

• • 1. Long and upright flowering stems.
  • 2. Uniform and freely flowering habit.
  • 3. Salmon-colored flowers.
  • 4. Excellent postproduction longevity.

Plants of the new Rose differ from plants of the parent selections in the following characteristics:

• • 1. Plants of the new Rose are more compact than plants of the parent selections.
  • 2. Plants of the new Rose are not as freely flowering as plants of the parent selections.
  • 3. Plants of the new Rose and the parent selections differ in flower color as plants of the parent selections have pink-colored flowers.

Plants of the new Rose can be compared to plants of the Rose cultivar Gracia, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Rose differed from plants of the cultivar Gracia in the following characteristics:

• • 1. Plants of the new Rose had shorter flowering stems than plants of the cultivar Gracia.
  • 2. Plants of the new Rose were narrower than plants of the cultivar Gracia.
  • 3. Plants of the new Rose had larger flowers than plants of the cultivar Gracia.
  • 4. Plants of the new Rose and the cultivar Gracia differed in flower color as plants of the cultivar Gracia had dark pink-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The new Rose has 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 about 1.5 years 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.
