USPP22554P2 - Poinsettia plant named ‘SYEP22866’ - Google Patents

Abstract

A new Poinsettia plant named ‘SYEP22866’ particularly distinguished by its intense red bract color, medium sized inflorescences with relatively many bracts and cyathia, dark-green foliage, leaves with only weak lobes, small to medium-sized, v-shaped and tight habit with relatively upright directed stems.

Description

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

Varietal denomination: ‘SYEP22866’.

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 ‘SYEP22866’.

‘SYEP22866’ is a product of a planned breeding program. The new cultivar ‘SYEP22866’ has intense red bracts, medium sized inflorescences with relatively many bracts and many cyathia, dark green foliage, and compact, v-shaped habit with relatively strong, upright directed stems.

‘SYEP22866’ originated from a hybridization made in the summer of 2003 in a controlled breeding program in Hillscheid, Germany. The female parent was the proprietary plant ‘10049’, not patented, having deep red flower color, dark green foliage, about medium sized habit, and early flowering.

The male parent of ‘SYEP22866’ was the proprietary plant designated No. ‘298’, not patented, with bright red bracts, dark green foliage, leaves with strong lobes, and upright plant habit with strong branches.

The resulting seeds were sown in February through March 2004 and ‘SYEP22866’ was selected as one flowering plant within the progeny of the stated cross in November/December 2004 in a greenhouse in Hillscheid, Germany.

The first act of asexual reproduction of ‘SYEP22866’ had been accomplished when shoot tip cuttings were used from the initial selection in late July 2004, rooted and cultivated for the above mentioned small trial.

More cuttings were used from the selected plant from April through May 2005 and grafted onto rootstocks of the variety ‘Maren’, in order to improve the branching ability. Shoot tip cuttings from successfully grafted stems were used in the summer of summer of 2007. They were rooted and cultivated as branched plants for a small trial in the fall and winter of 2007.

Horticultural examination of plants grown from cuttings of the plant initiated in the summer of 2007 in Hillscheid, Germany, and continuing thereafter on a larger scale, has demonstrated that the combination of characteristics as herein disclosed for ‘SYEP22866’ are firmly fixed and are retained through successive generations of asexual reproduction.

A Plant Breeder's Right for this cultivar has been applied for in Switzerland. A Plant Breeder's Right has also been applied for in Canada on Mar. 8, 2010 (No. 10-6883). ‘SYEP22866’ has not been made publicly available more than one year prior to the filing of this application.

‘SYEP22866’ 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 ‘SYEP22866’ with colors being as true as possible with an illustration of this type.

FIG. 1 shows a top view of the flower bracts of an about 17 week old plant taken on Nov. 19, 2010 at Lucas Greenhouses, Monroeville, N.J.

FIG. 2 shows a whole flowering plant. The picture had been taken in Hillscheid, Germany, on Nov. 12, 2008. It shows a 15 week old plant in a 14 cm pot.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Enkhuizen, Netherlands, on Dec. 16, 2010 on about 18 week old plants growing in a greenhouse. Culture of these plants had started on August 10 by planting rooted cuttings into 12 cm pots and pinching them 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. Intense red flower bract color
  • 2. Medium sized inflorescences with relatively many bracts and many cyathia
  • 3. Dark green foliage, weakly lobed leaves
  • 4. Small to medium sized, well-branched and tight, mounding plant habit
  • 5. V-shaped habit with relatively upright directed stems
  • 6. Early to medium flowering response
  • 7. Well suited for production of smaller plants without ‘rings’ (generally used for stabilisation and to avoid breaking off of branches) and good transportation ability

DIFFERENCES BETWEEN THE NEW VARIETY ‘SYEP22866’ AND SIMILAR VARIETIES

‘SYEP22866’ has roughly similar inflorescences and similar bract color as ‘Fisolymp’, U.S. Plant Pat. No. 14,662, but differs in plant habit. ‘SYEP22866’ is distinctly more compact with better transportation ability, while ‘Fisolymp’ tends to develop a wider plant habit.

In comparison to ‘Fiscor Dark Red’, U.S. Plant Pat. No. 12,723, ‘SYEP22866’ has bracts and leaves with no or less distinct lobes, and with narrower, more upright plant habit.

Compared with the commercial variety ‘Christmas Feelings’, U.S. Plant Pat. No. 14,618 under the designation ‘NPCW02044’, ‘SYEP22866’ develops a more compact plant habit, has a somewhat deeper red bract color, and inflorescences with longer bracts and more cyathia.
