USPP22623P2 - Poinsettia plant named ‘SYEP0791’ - Google Patents

Abstract

A new Poinsettia plant named ‘SYEP0791’ particularly distinguished by its bright red bract color, ovate bract shape, medium sized, horizontally shaped inflorescences, dark green foliage, leaf without lobes, medium sized, v-shaped plant habit, and early flowering.

Description

Latin name of the genus and species of the plant claimed: Euphorbia pulcherrima.

Varietal denomination: ‘SYEP0791’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Poinsettia plant, botanically known as Euphorbia pulcherrima, and hereinafter referred to by the variety name ‘SYEP0791’.

‘SYEP0791’ is a product of a planned breeding program. The new cultivar ‘SYEP0791’ has bright red colored, ovate bracts, dark green foliage, leaves nearly without any lobes, medium sized, v-shaped plant habit, and early flowering.

‘SYEP0791’ originated as a naturally occurring whole plant mutation of the parent variety ‘Fismars’ discovered by the inventor in November 2007 in a Poinsettia trial in Ahlem near Hannover, Germany. ‘Fismars’ has been disclosed in U.S. Plant Pat. No. 14,977. ‘Fismars’ has medium red bracts, dark-green foliage, and about mid season start of flowering.

As an earlier flowering line might be desirable, the mutated plant, ‘SYEP0791’, was taken to Hillscheid, Germany, for further examination and for evaluation of the stability of the new feature.

The first act of asexual reproduction of ‘SYEP0791’ was accomplished when shoot tips were cut and rooted in the spring of 2008. The resulting plants were grown out and in the end of July 2008 propagated and cultivated for the first trial in the fall and winter of 2008.

Horticultural examination of plants grown from cuttings of the plant initiated in the summer of 2008 in Hillscheid, Germany, and continuing thereafter on a larger scale, has demonstrated that the combination of characteristics as herein disclosed for ‘SYEP0791’ are firmly fixed and are retained through successive generations of asexual reproduction.

Plant Breeders' Rights for this cultivar were applied for in Canada on Mar. 8, 2010 (No. 10-6880), in the European Union on Nov. 4, 2010 (No. 2010/2356), and in Switzerland on Nov. 11, 2010 (No.10-2697). ‘SYEP0791’ has not been made publicly available more than one year prior to the filing of this application.

‘SYEP0791’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length

DESCRIPTION OF DRAWING

The accompanying photographic drawings show typical flower and foliage characteristics of ‘SYEP0791’ with colors being as true as possible with an illustration of this type.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Enkhuizen, Netherlands, on Dec. 16, 2010 on about 18 week old plants growing in a greenhouse. Cultivation of these plants had started on Aug. 10, 2010 when rooted cuttings were planted into 12 cm pots and pinched about 2 weeks later.

The plants were grown under natural day light in the fall (no black cloth was applied to initiate earlier flowering) and at the moderately warm temperature of 18°-20° C. for the bench heating.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown on benches in a greenhouse in Hillscheid, Germany. The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Poinsettia plant as a new and distinct variety.

• • 1. Bright red colored bracts with nearly no lobes
  • 2. Medium to large sized inflorescences, with the bracts flat and overlapping
  • 3. Dark green foliage, ovate leaves nearly without any lobes
  • 4. About medium vigor, v-shaped habit with upright directed stems
  • 5. Early flowering response
  • 6. Good packing and transportation ability

DIFFERENCES BETWEEN THE NEW VARIETY ‘SYEP0791’ AND SIMILAR VARIETIES

‘SYEP0791’ has a similar bract color as the parent, the commercial variety ‘Fismars’, disclosed in U.S. Plant Pat. No. 14,977. ‘SYEP0791’ differs mainly by its earlier start of flowering, and by its slightly lower plant habit, yet larger inflorescences.

In contrast to ‘Fismars 339’ (U.S. Plant Pat. No. 21,054), ‘SYEP0791’ has a somewhat less deep red main flower bract color and earlier flowering.

In comparison to the commercial variety ‘Freedom Red’, patented under the designation ‘490’, U.S. Plant Pat. No. 7,825, ‘SYEP0791’ has distinctly smaller bracts, edges of bracts and leaves with only very weak expression of lobes, and a narrower plant habit with more upright directed stems.
