Rose plant named ‘98-0036’

Abstract

A new and distinct cultivar of Rose plant named ‘98-0036’, characterized by its upright and rounded plant habit; dark green-colored leaflets; freely branching growth habit; freely flowering habit; large double creamy white-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘98-0036’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as a potted Rose, and hereinafter referred to by the name ‘98-0036’.

The new Rose is a product of a planned breeding program conducted by the Inventor in Fåborg, Denmark. The objective of the breeding program was to develop new uniform potted Rose varieties with novel and attractive flower colors, disease resistance and excellent postproduction longevity.

The new cultivar originated from a cross-pollination made by the Inventor on Mar. 1, 2004 of a proprietary Rose selection identified as code number MUT-08, not patented, as the female, or seed, parent with an unnamed Rose selection, not patented, as the male, or pollen, parent. The cultivar 98-0036 was discovered and selected by the Inventor on Feb. 10, 2005 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Fåborg, Denmark.

Asexual reproduction of the new Rose by cuttings in Fåborg, Denmark since Dec. 1, 2005, has shown that the unique features of this new Rose 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 ‘98-0036’. These characteristics in combination distinguish ‘98-0036’ as a new and distinct cultivar:

• • 1. Upright and rounded plant habit.
  • 2. Dark green-colored leaflets.
  • 3. Freely branching growth habit.
  • 4. Freely flowering habit.
  • 5. Large double creamy white-colored flowers.
  • 6. Flowers held upright on strong and erect peduncles.
  • 7. Good postproduction longevity.

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

• • 1. Plants of the new Rose and the parent selections differ in plant habit.
  • 2. Plants of the new Rose and the parent selections differ in flower color.

Plants of the new Rose can be compared to plants of the Rose cultivar Evera 122, disclosed in U.S. Plant patent application Ser. No. 11/700,607. In side-by-side comparisons conducted in Fåborg, Denmark, plants of the new Rose differed from plants of the cultivar Evera 122 in the following characteristics:

• • 1. Plants of the new Rose had longer lateral branches and shorter internodes than plants of the cultivar Evera 122.
  • 2. Plants of the new Rose had longer leaves than plants of the cultivar Evera 122.
  • 3. Plants of the new Rose had fewer stamens and pistils per flower than plants of the cultivar Evera 122.
  • 4. Plants of the new Rose and the cultivar Evera 122 differed in flower color as plants of the cultivar Evera 122 had pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose, 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 colors of the new Rose.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘98-0036’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flower of ‘98-0036’.

DETAILED BOTANICAL DESCRIPTION

The new Rose has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the autumn and winter in Fåborg, Denmark, in a glass-covered greenhouse and under commercial production practices. Plants were pinched one time and were about 12 to 14 weeks old when the photographs and description were taken. During the production of the plants, day temperatures averaged 22° C., night temperatures averaged 21° C. and light levels were about 20,000 lux. Three cuttings were grown in 12-cm containers. Plants used in the description represent a single plant. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
