Poinsettia plant named ‘PER1362’

Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1362’, characterized by its uniform, upright and mounded plant habit; vigorous growth habit; freely and upright to somewhat outwardly branching habit; dark green-colored leaves; under natural season conditions, plants flower on or about November 8 in Southern California; large inflorescences with peach-colored flower bracts with dark pink-colored flecks and spots; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER1362’.

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 cultivar name ‘PER1362’.

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 uniform Poinsettia plants having large inflorescences with attractive flower bracts and excellent post-production longevity.

The new Poinsettia plant originated from a cross-pollination made by the Inventor in December, 2007 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number PE2-31, not patented, as the female, or seed, parent, with Euphorbia pulcherrima Willd. ‘PER2804’, disclosed in U.S. Plant Pat. No. 19,295, 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, 2008.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since February, 2009 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 combinations of 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 ‘PER1362’. These characteristics in combination distinguish ‘PER1362’ as a new and distinct Poinsettia plant:

• • 1. Uniform, upright and mounded plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely and upright to somewhat outwardly branching habit.
  • 4. Dark green-colored leaves.
  • 5. Under natural season conditions, plants flower on or about November 8 in Southern California.
  • 6. Large inflorescences with peach-colored flower bracts with dark pink-colored flecks and spots.
  • 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 the following characteristics:

• • 1. Plants of the new Poinsettia have more vigorous than plants of the female parent selection.
  • 2. Plants of the new Poinsettia and the female parent selection differ in leaf and flower bract aspect plants of the female parent selection have leaves and flower bracts that are reflexed.
  • 3. Plants of the new Poinsettia flower about twelve days earlier than plants of the female parent selection when grown under natural season conditions.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differ primarily from plants of the male parent, ‘PER2804’, in the following characteristics:

• • 1. Plants of the new Poinsettia have darker green-colored leaves than plants of ‘PER2804’.
  • 2. Plants of the new Poinsettia have smaller flower bracts than plants of ‘PER2804’.
  • 3. Plants of the new Poinsettia and ‘PER2804’ differ in flower bract color as plants of ‘PER2804’ have bright red-colored flower bracts.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Peterstar Pink’, disclosed in U.S. Plant Pat. No. 9,879. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘Peterstar Pink’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more vigorous than plants of ‘Peterstar Pink’.
  • 2. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Peterstar Pink’.
  • 3. Plants of the new Poinsettia and ‘Peterstar Pink’ differed in flower bract color as plants of ‘Peterstar Pink’ had pink-colored flower bracts.
  • 4. Plants of the new Poinsettia flowered about 17 days earlier than plants of ‘Peterstar Pink’.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘PER975’, disclosed in U.S. Plant Pat. No. 16,882. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘PER975’ in the following characteristics:

• • 1. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘PER975’.
  • 2. Plants of the new Poinsettia and ‘PER975’ differed in flower bract color as plants of ‘PER975’ had light pink to pale yellow-colored flower bracts.
  • 3. Plants of the new Poinsettia flowered about 13 days earlier than plants of ‘PER975’.

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 26° 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 21 weeks old when the photographs and the description were taken.
