Abstract

A distinctive cultivar of Hybrid Tea Rose plant named ‘Yolitor’, characterized by its glossy dark green leaves; long and dark red stems; large light orange flowers; and good postproduction longevity.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Rosa hybrida cultivar Yolitor.
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 ‘Yolitor’.
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 the cultivar Pareo, not patented, as the female, or seed, parent with the cultivar Mango, not patented, as the male, or pollen, parent. The cultivar Yolitor 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 ‘Yolitor’. These characteristics in combination distinguish the new Hybrid Tea Rose as a new and distinct cultivar:
1. Glossy dark green leaves.
2. Long and dark red stems.
3. Large light orange flowers.
4. Good postproduction longevity.
Plants of the Hybrid Tea Rose can be compared to plants of the female parent, the cultivar Pareo. In side-by-side comparisions conducted by the Inventor in Salinas, Calif., plants of the new cultivar differed from plants of the cultivar Pareo in the following characteristics:
1. Flowering stems of the new Hybrid Tea Rose have more thorns than flowering stems of the cultivar Pareo.
2. Plants of the new Hybrid Tea Rose have longer flowering stems than plants of the cultivar Pareo.
3. Plants of the new Hybrid Tea Rose have light orange-colored flower petals whereas plants of the cultivar Pareo have apricot-colored flower petals.
Plants of the Hybrid Tea Rose can be compared to plants of the femal parent, the cultivar Mango. In side-by-side comparisions conducted by the Inventor in Salinas, Calif., plants of the new cultivar differed from plants of the cultivar Mango in the following characteristics:
1. Plants of the new Hybrid Tea Rose have much longer flowering stems than plants of the cultivar Mango.
2. Flowering stems of the new Hybrid Tea Rose have more thorns than flowering stems of the cultivar Mango
3. Plants of the new Hybrid Tea Rose have light orange-colored flower petals whereas plants of the cultivar Mango have golden 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
