USPP17809P2 - Rose plant named ‘Evera 141’ - Google Patents

Abstract

A new and distinct cultivar of rose plant named ‘Evera 141’, characterized by its upright and rounded plant habit; dark green-colored leaves; freely flowering habit; large fully double red-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Evera 141’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the Rose class, botanically known as Rosa hybrida, commercially known as a potted Rose and hereinafter referred to by the name ‘Evera 141’.

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

The new Rose plant originated from a cross-pollination made by the Inventor on Mar. 1, 2003 of two unnamed proprietary Rosa hybrida seedlings, not patented. The cultivar Evera 141 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Denmark. Plants of the new cultivar differ primarily from plants of the parent selections primarily in flower color.

Asexual reproduction of the new Rose plant by cuttings in Denmark since Feb. 10, 2004, 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 new Rose plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Evera 141’. These characteristics in combination distinguish the new Rose plant as a new and distinct cultivar:

• • 1. Upright and rounded plant habit.
  • 2. Dark green-colored leaves.
  • 3. Freely flowering habit.
  • 4. Large fully double dark red-colored flowers.
  • 5. Flowers held upright on strong and erect peduncles.
  • 6. Good postproduction longevity.

Plants of the new Rose plant can be compared to plants of the Rose cultivar Evera 103, disclosed in U.S. Plant Pat. No. 16,780. In side-by-side comparisons conducted in Denmark, plants of the new Rose differed from plants of the cultivar Evera 103 in the following characteristics:

• • 1. Plants of the new Rose were more freely flowering than plants of the cultivar Evera 103.
  • 2. Plants of the new Rose had smaller flowers with twice as many petals per flower than plants of the cultivar Evera 103.
  • 3. Plants of the new Rose and the cultivar Evera 103 differed in flower coloration as plants of the cultivar Evera 103 had yellow orange-colored flowers.
