Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1303’, characterized by its uniform, upright and mounded plant habit; moderately vigorous growth habit; freely and upright branching habit; dark green-colored leaves; mid-season flowering response; large inflorescences with dark red-colored flower bracts; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER1303’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name ‘PER1303’.

The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new upright branching Poinsettia plants having large inflorescences with red-colored flower bracts, mid-season flowering response and excellent post-production longevity.

The new Poinsettia plant originated from a cross-pollination made by the Inventor in December, 2006 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 05-447, not patented, as the female, or seed, parent, with a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 80-02, not patented, as the male, or pollen, parent. The new Poinsettia 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 Encinitas, Calif. in December, 2007.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since January, 2008 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Poinsettia 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, daylength 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 ‘PER1303’. These characteristics in combination distinguish ‘PER1303’ as a new and distinct Poinsettia plant:

• • 1. Uniform, upright and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely and upright branching habit.
  • 4. Dark green-colored leaves.
  • 5. Mid-season flowering response; under natural season conditions, plants flower in late November in Southern California.
  • 6. Large inflorescences with dark red-colored flower bracts.
  • 7. Good post-production longevity.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differ primarily from plants of the female parent selection in flower bract color as plants of the new Poinsettia have darker red-colored flower bracts than plants of the female parent selection.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differ primarily from plants of the male parent selection in flowering response as plants of the new Poinsettia flower about ten days later than plants of the male parent selection. In addition, plants of the new Poinsettia and the male parent selection differ slightly in flower bract color.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Peterstar’, disclosed in U.S. Plant Pat. No. 8,259. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘Peterstar’ in the following characteristics:

• • 1. Branching habit of plants of the new Poinsettia was more upright than branching habit of plants of ‘Peterstar’.
  • 2. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Peterstar’.
  • 3. Plants of the new Poinsettia had darker red-colored flower bracts than plants of ‘Peterstar’.

Plants of the new Poinsettia can also be compared to plants of the Euphorbia pulcherrima Willd. ‘490’, disclosed in U.S. Plant Pat. No. 7,825. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘490’ in response time as plants of the new Poinsettia flowered about one week later than plants of ‘490’ when grown under natural season conditions. In addition, plants of the new Poinsettia had a more upright branching habit than plants of ‘490’.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following detailed description were grown during the late autumn/early winter in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under natural season conditions and cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 18° C. and light levels averaged 5,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were 17 weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
