USPP25790P2 - Portulaca plant named ‘Duecupyecro’ - Google Patents

Abstract

A new and distinct cultivar of Portulaca plant named ‘Duecupyecro’, characterized by its semi-upright to spreading growth habit; vigorous growth habit; freely branching habit; freely flowering habit; and bright yellow and red-colored flowers.

Description

Botanical designation: Portulaca hybrida.

Cultivar denomination: ‘DUECUPYECRO’.

BACKGROUND OF THE INVENTION

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

The new Portulaca 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 semi-upright Portulaca plants with numerous attractive flowers.

The new Portulaca plant originated from a cross-pollination made by the Inventor in Rheinberg, Germany in July, 2010 of a proprietary selection of Portulaca hybrida identified as code number F-1815-025, not patented, as the female, or seed, parent with a proprietary selection of Portulaca hybrida identified as code number F-1607-013, not patented, as the male, or pollen, parent. The new Portulaca plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2012.

Asexual reproduction of the new Portulaca plant cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2012, has shown that the unique features of this new Portulaca plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Portulaca 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 ‘Duecupyecro’. These characteristics in combination distinguish ‘Duecupyecro’ as a new and distinct Portulaca plant:

• • 1. Semi-upright to spreading growth habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Bright yellow and red-colored flowers.

Plants of the new Portulaca can be compared to plants of the female parent selection. Plants of the new Portulaca differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have orange red-colored flowers.

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

Plants of the new Portulaca also can be compared to plants of the Portulaca ‘Sun Dance Gold’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Portulaca differed primarily from plants of ‘Sun Dance Gold’ in the following characteristics:

• • 1. Plants of the new Portulaca were larger than plants of ‘Sun Dance Gold’.
  • 2. Plants of the new Portulaca had smaller and darker green-colored leaves than plants of ‘Sun Dance Gold’.
  • 3. Plants of the new Portulaca and ‘Sun Dance Gold’ differed slightly in flower color.
  • 4. Plants of the new Portulaca had longer and thicker peduncles than plants of ‘Sun Dance Gold’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Portulaca plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Portulaca plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Duecupyecro’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Portulaca production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 20 weeks old when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
