Rose plant named ‘Evera607’

Abstract

A new and distinct cultivar of Rose plant named ‘Evera607’, characterized by its upright and mounding plant habit; dark green-colored leaflets; large white-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘EVERA607’.

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 plant and hereinafter referred to by the name ‘Evera607’.

The new Rose plant 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 Rose plant originated from an open-pollination made by the Inventor in April, 2008 of Rosa hybrida ‘Evera209’, disclosed in U.S. Plant Pat. No. 21,468, as the female, or seed, parent with an unknown proprietary Rose selection as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor in September, 2009 as a single flowering plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Fåborg, Denmark.

Asexual reproduction of the new Rose plant by cuttings in a controlled greenhouse environment at Fåborg, Denmark since October, 2009 has shown that the unique features of this new Rose plant 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 ‘Evera607’. These characteristics in combination distinguish ‘Evera607’ as a new and distinct Rose plant:

• • 1. Upright and mounding plant habit.
  • 2. Dark green-colored leaflets.
  • 3. Large white-colored flowers.
  • 4. Flowers held upright on strong and erect peduncles.
  • 5. Good postproduction longevity.

Plants of the new Rose differ from plants of the female parent, ‘Evera209’ in the following characteristics:

• • 1. Stems of plants of the new Rose are slightly pubescent whereas stems of plants of ‘Evera209’ are glabrous.
  • 2. Plants of the new Rose have larger flowers than plants of ‘Evera209’.
  • 3. Flowers of plants of the new Rose are longer lasting than flowers of plants of ‘Evera209’.

Plants of the new Rose can be compared to plants of the Rose ‘Evera211’, disclosed in U.S. Plant Pat. No. 21,470. In side-by-side comparisons conducted in Fåborg, Denmark, plants of the new Rose differed from plants of ‘Evera21’ in the following characteristics:

• • 1. Plants of the new Rose had longer flower buds than plants of ‘Evera211’.
  • 2. Plants of the new Rose had thicker and stronger peduncles than plants of ‘Evera211’.
  • 3. Plants of the new Rose and ‘Evera211’ differed in flower color as plants of ‘Evera211’ had yellow-colored flowers.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the spring in Sabro, Denmark, in a glass-covered greenhouse and under cultural practices typical of commercial potted Rose production. Plants were grown in 10-cm containers, pinched two times and were three months old when the photographs and description were taken. During the production of the plants, day temperatures averaged 21° C., night temperatures averaged 19° C. and light levels ranged from 8,000 to 10,000 lux.
