Abstract

A distinct cultivar of hybrid tea rose plant named `Preveris`, characterized by its large yellow and orange flowers; long and strong stems; dark green leaves; and good postproduction longevity.

Description

The present invention relates to a new and distinct cultivar of hybrid tea rose plant, botanically known as Rosa hybrida, commercially used as a cut flower, and hereinafter referred to by the cultivar name Preveris.
The new cultivar is a product of a planned breeding program conducted by the inventor in Rijsenhout, The Netherlands. The objective of the breeding program was to develop cut rose varieties with novel and attractive flower colors, long and strong stems, dark leaves, and good postproduction longevity. The new cultivar originated from a cross made by the inventor in 1993 of two proprietary seedlings. The proprietary selection P151 was the female, or seed, parent, and the proprietary selection 92-331 was the male, or pollen, parent. The cultivar Preveris was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Rijsenhout, The Netherlands.
Asexual propagation of the new cultivar by cuttings taken at Rijsenhout, The Netherlands, has shown that the unique features of this new rose plant are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and are determined to be unique characteristics of `Preveris`. These characteristics in combination distinguish the new rose plant as a new and distinct cultivar:
1. Large yellow and orange flowers.
2. Long and strong stems.
3. Dark green leaves.
4. Good postproduction longevity.
The new rose plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light or fertility level, without, however, any variance in genotype.
BRIEF DESCRIPTION OF PHOTOGRAPH
The accompanying colored photograph illustrates the new rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph comprises a top perspective view of typical flowering stems of the new rose plant grown in Rijsenhout, The Netherlands. Flower and foliage color in these photographs may appear different from the actual colors due to light reflectance.
