Abstract

A distinctive cultivar of Hybrid Tea Rose plant named ‘Yohopi’, characterized by its glossy dark green leaves; long, thick and dark red stems that do not have thorns; large dark pink-colored flowers with ruffled petal margins; and good postproduction longevity.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Rosa hybrida cultivar Yohopi.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hybrid Tea Rose plant, botanically known as Rosa hybrida, commercially produced as a cut flower, and hereinafter referred to by the name ‘Yohopi’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. The objective of the breeding program was to develop new cut Rose cultivars with attractive flower petal colors, long and strong stems, dark green leaves and good postproduction longevity.
The new cultivar originated from a cross made by the Inventor in 1996 of an unnamed proprietary selection as the female, or seed, parent with the Rose cultivar Laura, not patented, as the male, or pollen, parent. The cultivar Yohopi was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in April, 1998, in Madrid, Cundinamarca, Colombia.
Since December, 1998, asexual reproduction of the new cultivar by grafting on Rosa Manetti rootstocks in Madrid, Cundinamarca, Colombia, has shown that the unique features of the new cultivar 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 ‘Yohopi’. These characteristics in combination distinguish the new Hybrid Tea Rose as a new and distinct cultivar:
1. Glossy dark green leaves.
2. Long, thick and dark red stems that do not have thorns.
3. Large dark pink-colored flowers with ruffled petal margins.
4. Good postproduction longevity.
Plants of the Hybrid Tea Rose can be compared to plants of the female parent, an unnamed proprietary selection. In side-by-side comparisons conducted by the Inventor in Salinas, Calif., plants of the new cultivar differed from plants of the unnamed proprietary selection in the following characteristics:
1. Plants of the new Hybrid Tea Rose do not have thorns whereas plants of the unnamed proprietary selection have thorns.
2. Plants of the new Hybrid Tea Rose have dark pink-colored flower petals whereas plants of the unnamed proprietary selection have yellow-colored flower petals.
Plants of the Hybrid Tea Rose can be compared to plants of the male parent, the cultivar Laura. In side-by-side comparisons conducted by the Inventor in Salinas, Calif., plants of the new cultivar differed from plants of the cultivar Laura in the following characteristics:
1. Plants of the new Hybrid Tea Rose have much longer stems than plants of the cultivar Laura.
2. Plants of the new Hybrid Tea Rose do not have thorns whereas plants of the cultivar Laura have thorns.
3. Plants of the new Hybrid Tea Rose have dark pink-colored flower petals whereas plants of the cultivar Laura have yellow-colored flower petals.
Plants of the new Hybrid Tea Rose have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light, water status and/or fertilizer type and rate, without, however, any variance in genotype.
BRIEF DESCRIPTION OF PHOTOGRAPH
The accompanying colored photograph illustrates the new Hybrid Tea Rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hybrid Tea Rose. The photograph comprises a side perspective view of a typical flowering stem of the new Hybrid Tea Rose grown in Madrid, Cundinamarca, Colombia.
DETAILED BOTANICAL DESCRIPTION
The following observations and measurements describe cut flowering stems of plants grown in Madrid, Cundinamarca, Colombia, in polyethylene-covered greenhouses with day temperatures ranging from 14 to 20° C., night temperatures ranging from 4 to 8° C., and light levels ranging from 3,000 to 5,000 foot-candles. Flowering stems used in the photograph and the description were about 75 days old.
