Rose plant named ‘Esm Fant’

Abstract

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

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Esm Fant’.

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 Fant’.

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 May, 2001 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 42, not patented, as the male, or pollen, parent. The cultivar Esm Fant 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, 2002, 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 Fant’. These characteristics in combination distinguish ‘Esm Fant’ as a new and distinct cultivar:

• • 1. Long and upright flowering stems.
  • 2. Uniform and freely flowering habit.
  • 3. Dark red-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 have longer flowering stems than plants of the parent selections.
  • 2. Plants of the new Rose are more freely flowering than plants of the parent selections.
  • 3. Plants of the new Rose and the parent selections differ in flower color.

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

• • 1. Plants of the new Rose had longer flowering stems than plants of the cultivar Red Mikado.
  • 2. Plants of the new Rose were more freely branching than plants of the cultivar Red Mikado.
  • 3. Plants of the new Rose flowered later than plants of the cultivar Red Mikado.
  • 4. Plants of the new Rose were more freely flowering than plants of the cultivar Red Mikado.
  • 5. Flowers of plants of the new Rose were longer-lasting than flowers of plants of the cultivar Red Mikado.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose, 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 top of the sheet comprises a side perspective view of a typical flowering stem of ‘Esm Fant’.

The photograph at the bottom of the sheet is a close-up view of a typical flower of ‘Esm Fant’.

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 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.
