plant named ‘gen R273’

Botanical designation:

Cultivar denomination: ‘GEN R273’.

A European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Genviv Holdings, LLC of Miami, Florida on Aug. 9, 2025, application number 2025/1777. Foreign priority is not claimed to this European Community Plant Breeder's Rights application.

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as, commercially produced and used as a cut flower Rose plant, and hereinafter referred to by the name ‘GEN R273’.

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 unique flower colors and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor in March 2012 of a proprietary Rose selection identified as line R758, not patented, as the female, or seed, parent with a proprietary Rose selection identified as line R673, 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 August 2013.

Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since February 2014 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

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 ‘GEN R273’. These characteristics in combination distinguish ‘GEN R273’ as a new and distinct Rose plant:

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

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

Plants of the new Rose can also be compared to plants of‘GEN R233’, not patented. In side-by-side comparisons, plants of the new Rose differ from plants of ‘GEN R233’ in the following characteristics:

The aforementioned photographic sheet and the following observations and measurements describe plants grown in ground beds in a polyethylene-covered greenhouse in Cayambe, Pichincha, Ecuador and produced under typical cut Rose production practices. Plants were grown year round and were 30 months old when the photographs and the description were taken. During the production of the plants, day temperatures ranged from 17° C. to 21° C., night temperatures ranged from 5° C. to 8° C. and light levels averaged 19,338 lux.
