Poinsettia plant named ‘PER1072’

Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1072’, characterized by its inflorescences with recurved red-colored flower bracts; recurved dark green-colored leaves; uniform, compact, upright and mounded plant habit; early season flowering; natural season flower maturity date is mid-November for plants grown in Encinitas, Calif., and excellent post-production longevity.

Description

Bontanical designation: Euphorbia pulcherrima Willd.

Variety denomination: ‘PER1072’.

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 ‘PER1072’.

The new Poinsettia 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 early flowering Poinsettia cultivars having strong stems, recurved leaves and flower bracts, attractive flower bract coloration, uniform plant habit and excellent post-production longevity.

The new Poinsettia originated from a cross-pollination made by the Inventor in December, 1999, of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number V-82, not patented, as the female, or seed, parent, with a proprietary selection of Euphorbia pulcherrima Willd. identified as V-01, not patented, as the male, or pollen, parent. The cultivar PER979 was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Encinitas, Calif, in December, 2000.

Asexual reproduction of the new Poinsettia by terminal cuttings propagated in a controlled environment in Encinitas, Calif., since July, 2001, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PER1072’. These characteristics in combination distinguish ‘PER1072’ as a new and distinct cultivar:

• • 1. Inflorescences with recurved red-colored flower bracts.
  • 2. Recurved dark green-colored leaves.
  • 3. Uniform, compact, upright and mounded plant habit.
  • 4. Early season flowering; natural season flower maturity date is mid-November for plants grown in Encinitas, Calif.
  • 5. Excellent post-production longevity.

Plants of the new Poinsettia differ from plants of the female parent selection primarily in flower bract color as plants of the female parent selection have bi-colored flower bracts.

Plants of the new Poinsettia have darker-colored leaves and flower bracts than plants of the male parent selection.

Plants of the new Poinsettia can be compared to plants of the cultivar Windark, disclosed in U.S. Plant Pat. No. 12,546. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily in time to flower as plants of the new Poinsettia flowered about two weeks earlier than plants of the cultivar Windark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘PER1072’ grown in a container.

The photograph at the bottom left of the sheet is a close-up view of typical inflorescences of ‘PER1072’.

The photograph at the bottom right of the sheet comprises a top perspective view of a typical plant of ‘PER1072’.

DETAILED BOTANICAL DESCRIPTION

The new Poinsettia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and averaged measurements describe plants grown in Encinitas, Calif. during the autumn and winter under commercial practice in a polyethylene-covered greenhouse with day temperatures averaging about 24° C., night temperatures averaging about 19° C. and light levels about 4,000 foot-candles. Single plants were grown in 16.5-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 15 weeks from unrooted cuttings when the photographs and the detailed botanical description were taken.
