plant named ‘Alegnuflor942’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Alegnuflor942’, characterized by its upright and somewhat vining to climbing plant habit; moderately vigorous growth habit; early and freely flowering habit; long flowering period; dark red-colored flowers; and good garden performance.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘ALEGNUFLOR942’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Alegnuflor942’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new Mandevilla plants with large attractive flowers and are temperature-tolerant and tolerant to pathogens and pests common to Mandevilla plants.

The new Mandevilla plant originated from a cross-pollination made by the Inventor in Cobbitty, New South Wales, Australia in January, 2006 of a proprietary selection of Mandevilla hybrida identified as code number X03.2.8, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number X03.2.2, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Cobbitty, New South Wales, Australia in December, 2009.

Asexual reproduction of the new Mandevilla plant by cuttings in Macquarie Fields, New South Wales, Australia since January, 2010 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Alegnuflor942’. These characteristics in combination distinguish ‘Alegnuflor942’ as a new and distinct Mandevilla plant:

• • 1. Upright and somewhat vining to climbing plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Long flowering period.
  • 5. Dark red-colored flowers.
  • 6. Good garden performance.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Mandevilla are not as strongly vining as plants of the female parent selection.
  • 2. Plants of the new Mandevilla have smaller flowers than plants of the female parent selection.
  • 3. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have burgundy-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Mandevilla have smaller flowers than plants of the male parent selection.
  • 2. Plants of the new Mandevilla and the male parent selection differ in flower color as plants of the male parent selection have lighter red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Rio Red’, not patented. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Mandevilla differed primarily from plants of ‘Rio Red’ in the following characteristics:

• • 1. Plants of the new Mandevilla were more vigorous than plants of ‘Rio Red’.
  • 2. Plants of the new Mandevilla had slightly smaller flowers than plants of ‘Rio Red’.
  • 3. Plants of the new Mandevilla and ‘Rio Red’ differed in flower color as plants of ‘Rio Red’ had lighter red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Pretty Red’, not patented. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Mandevilla differed primarily from plants of ‘Pretty Red’ in the following characteristics:

• • 1. Plants of the new Mandevilla were not as vining as plants of ‘Pretty Red’.
  • 2. Plants of the new Mandevilla had thicker leaves than plants of ‘Pretty Red’.
  • 3. Plants of the new Mandevilla had smaller flowers than plants of ‘Pretty Red’.
