plant named ‘Dueswepurto17’

Abstract

A new and distinct cultivar of Petunia plant named ‘Dueswepurto17’, characterized by its medium to compact plant size; mounding to trailing plant habit; moderately vigorous growth habit; freely branching habit; early and freely flowering habit; relatively large flowers with white and purple violet bi-colored petals; and good garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘DUESWEPURTO17’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia X hybrida and hereinafter referred to by the name ‘Dueswepurto17’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new moderately vigorous and early-flowering Petunia plants with numerous attractive flowers.

The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2014 in Rheinberg, Germany of a proprietary selection of Petunia X hybrida identified as code number TT13-005765-008, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number TT13-002573-010, not patented, as the male, or pollen, parent. The new Petunia 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 Rheinberg, Germany in May, 2016.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2016 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of 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 ‘Dueswepurto17’. These characteristics in combination distinguish ‘Dueswepurto17’ as a new and distinct Petunia plant:

• • 1. Medium to compact plant size, mounding to trailing plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Purple violet and white bi-colored flowers.
  • 6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in plant size as plants of the new Petunia are more compact than plants of the female parent selection. In addition, plants of the new Petunia and the female parent selection differ in flower color as plants of the female parent selection have blue and yellow bi-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have red and white-colored flowers.

Plants of the new Petunia can be compared to plants of Petunia X hybrida ‘Cascadias Bicolor Purple’, not patented. Plants of the new Petunia and ‘Cascadias Bicolor Purple’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia are more compact than plants of ‘Cascadias Bicolor Purple’.
  • 2. Plants of the new Petunia flower earlier than plants of ‘Cascadias Bicolor Purple’.
  • 3. Plants of the new Petunia and ‘Cascadias Bicolor Purple’ differ in flower color as plants of ‘Cascadias Bicolor Purple’ have purple and white bi-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Petunia production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were 13 weeks old when the photograph and description were taken.
