Rose plant named ‘ESM R129’

Abstract

A new and distinct cultivar of Rose plant named ‘ESM R129’, characterized by its upright, long and strong flowering stems; vigorous growth habit and high productivity; dark green-colored leaves; red-colored flowers that are typically grown as single-stem types; and excellent postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘ESM R129’.

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 R129’.

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 cut flower Rose varieties with attractive flowers and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor in February, 2008 of a proprietary Rose selection identified as Line 42, not patented, as the female, or seed, parent with a proprietary Rose selection identified as Line 406, 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 May, 2009.

Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since March, 2010 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 R129’. These characteristics in combination distinguish ‘ESM R129’ as a new and distinct Rose plant:

• • 1. Upright, long and strong flowering stems.
  • 2. Vigorous growth habit and high productivity.
  • 3. Dark green-colored leaves.
  • 4. Red-colored flowers that are typically grown as single-stem types.
  • 5. 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 longer flowering stems than plants of female parent selection.
  • 2. Flowers of plants of the new Rose have more petals than flowers of plants of the female parent selection.
  • 3. Flowers of plants of the new Rose are longer-lasting than flowers of plants of the 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 produce more flowering stems than plants of the male parent selection.
  • 2. Flowers of plants of the new Rose are longer-lasting than flowers of plants of the male parent selection.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘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 had longer and stronger flowering stems than plants of ‘Freedom’.
  • 2. Plants of the new Rose were more vigorous than plants of ‘Freedom’.
  • 3. Plants of the new Rose had fewer thorns than plants of ‘Freedom’.
  • 4. Plants of the new Rose had larger flower buds than plants of ‘Freedom’.
  • 5. Flowers of plants of the new Rose were longer-lasting than flowers of plants of ‘Freedom’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown in 10-liter containers in a polyethylene-covered greenhouse in El Quinche, Pichincha, Ecuador and under typical hydroponic Rose production practices. Plants were pinched 13 to 14 weeks after planting and were two years and 47 weeks old when the description and photographs 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.
