Abstract

A distinctive cultivar of Hybrid Tea Rose plant named ‘Schirus’, characterized by its dark green-colored leaves; vigorous growth habit; long and strong flowering stems; large white-colored flowers with numerous petals; high yield of cut flowering stems; and good postproduction longevity.

Description

Botanical classification/cultivar designation: Rosa hybrida cultivar Schirus.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hybrid Tea Rose plant, botanically known as Rosa hybrida, and hereinafter referred to by the cultivar name Schirus.
The new cultivar is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program was to develop new cut Rose cultivars with a high yield of cut flowering stems, attractive flower color, long and strong stems, dark green leaves and good postproduction longevity.
The new cultivar originated from a cross made by the Inventor in 1999 of two unnamed proprietary selections, not patented. The cultivar Schirus was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in De Kwakel, The Netherlands. The new cultivar differs primarily from plants of the parental unnamed proprietary selections in flower color.
Asexual reproduction of the new cultivar by cuttings taken at De Kwakel, The Netherlands, since 2000, 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 ‘Schirus’. These characteristics in combination distinguish the new Hybrid Tea Rose as a new and distinct cultivar:
    • 1. Dark green-colored leaves.
    • 2. Vigorous growth habit.
    • 3. Long and strong flowering stems.
    • 4. Large white-colored flowers with numerous petals.
    • 5. High yield of cut flowering stems.
    • 6. Good postproduction longevity.
Plants of the new Hybrid Tea Rose can be compared to plants of the cultivar Schreblank, not patented. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Hybrid Tea Rose differed from plants of the cultivar Schreblank in the following characteristics:
    • 1. Plants of the new Hybrid Tea Rose had longer flowering stems than plants of the cultivar Schreblank.
    • 2. Flowers of plants of the new Hybrid Tea Rose had more petals than flowers of plants of the cultivar Schreblank.
BRIEF DESCRIPTION OF PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Hybrid Tea Rose.
The photograph at the top of the sheet comprises a side perspective view of a typical flower of the new Hybrid Tea Rose.
The photograph at the bottom of the sheet comprises a top perspective view of the lower surface (left) and the upper surface (right) of typical leaves of the new Hybrid Tea Rose.
 DETAILED BOTANICAL DESCRIPTION
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 and light without, however, any variance in genotype.
The aforementioned photographs, following observations and measurements describe plants grown in De Kwakel, The Netherlands, in glass-covered greenhouses with an average day temperature of 19° C. and an average night temperature of 15° C. Plants used for the photographs and the description were about five months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
