Poinsettia plant named ‘SYEP22432’

Abstract

A new Poinsettia plant named ‘SYEP22432’ particularly distinguished by the bright red flower color, relatively large inflorescences with bracts a little upright directed, dark green foliage, early flowering response, and medium to strong vigor with good branching.

Description

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

Varietal denomination: ‘SYEP22432’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Poinsettia, botanically known as Euphorbia pulcherrima, and hereinafter referred to by the variety name ‘SYEP22432’.

‘SYEP22432’ is a product of a planned breeding program. The new cultivar has bright red flower color, relatively large inflorescences with bracts a little upright directed, dark green foliage, early flowering response, and medium to strong vigor with good branching.

‘SYEP22432’ originated from a hybridization made in the summer of 2003 in a controlled breeding environment in Hillscheid, Germany. The seed was sown in February 2004. The first act of asexual reproduction was accomplished in July 2004, when the shoot tip of each seedling plant was propagated.

The female parent was the proprietary plant designated ‘# 892’, unpatented, with deep bluish red bract color, larger dark green leaves, upright and vigorous habit, and mid-season flowering response.

The male parent of ‘SYEP22432’ was the proprietary plant designated as ‘Fispoin 7776’ with large red bracts, dark green foliage with moderate lobes and about medium sized plant habit with relatively upright directed stems.

‘SYEP22432’ was selected as one flowering plant within the progeny of the stated cross in December 2004 in a controlled environment in Hillscheid, Germany. In April 2005, additional shoot tips were cut and grafted on rootstocks of the variety ‘Maren’, in order to improve the branching ability. Shoot tip cuttings from the successfully grafted stems were rooted in the summer of 2006 and cultivated for the first trial through the fall and winter of 2006 in a greenhouse in Hillscheid, Germany.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in April 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘SYEP22432’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘SYEP22432’ 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.

Plant Breeder's Rights for this cultivar were applied for in Canada on Feb. 11, 2009 and in Switzerland on Mar. 19, 2009. ‘SYEP22432’ has not been made publicly available more than one year prior to the filing of this application.

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 as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘SYEP22432’ with colors being as true as possible with an illustration of this type. The photographic drawings show flowering potted plants of the new variety.

FIG. 1, taken on Nov. 12, 2008 shows a view of the bracts from the top of plant, on a plant about 20 weeks old;

FIG. 2, taken on Nov. 20, 2008, shows a side view of a 16 week old plant.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany in mid December 2008 on about 20 week old plants growing in a greenhouse. Culture of these plants had started in late July 2008 with planting rooted cuttings in 14 cm pots and terminal pinching about 2 weeks later. The plants were grown under natural day light in the fall (no black cloth to initiate earlier flowering) and at the moderately warm temperature of 18° C. for the bench heating.
