Poinsettia plant named ‘Fismars 339’

Abstract

A new poinsettia plant named ‘Fismars 339’ particularly distinguished by brilliant red flower color, large, rosette-like, flat inflorescence, dark green, ovate shaped leaves, evenly branching, medium size, good shape for packing and transportation, mid season flowering and good keeping characteristics.

Description

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

Varietal denomination: ‘Fismars 339’.

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 ‘Fismars 339.’

‘Fismars 339’ is a product of a planned breeding program. The new cultivar ‘Fismars 339’ has brilliant red bracts, dark green foliage, mid season flowering, and about medium sized plant habit.

‘Fismars 339’ originated from an induced mutation discovered in the parent variety ‘Fismars’ (U.S. Plant Pat. No. 14,977).

Irradiations of young plants of the variety ‘Fismars’ had been made in Ahrenburg, Germany, in May 2003. The treated plants were grown out in Hillscheid, Germany, and propagated by shoot cuttings. The resulting plants were screened for positive mutations. In the spring of 2004, a branch mutation was discovered, which was grown and examined as a separate clone.

Horticultural examinations of plants grown from cuttings of the plant were made in the fall to winter of 2005. Examinations continuing thereafter on a larger scale, have demonstrated that the combination of characteristics as herein disclosed for ‘Fismars 339’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Fismars 339’ 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 Breeders' Rights for this cultivar were applied for in the European Union on Jun. 2, 2008 and in Canada on Jul. 4, 2008. ‘Fismars 339’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF DRAWING

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fismars 339’ with colors being as true as possible with an illustration of this type. The photographic drawing is a flowering pot, taken on Dec. 1, 2008, with plants potted in mid July 2008, about 19 weeks old.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in in Hillscheid, Germany, latitude 50° north, in mid December 2008 on plants that were grown on benches in a greenhouse. Culture of these plants had started in late July 2008 with planting rooted cuttings in 14 cm pots and 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.

Color Chart used: Royal Horticultural Society Colour Chart (RHS) 2001

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. Brilliant-red bracts, nearly without any lobes
  • 2. Relatively large, flat, rosette-like inflorescences
  • 3. Dark green foliage, ovate-shaped leaves
  • 4. Medium sized, evenly mounding plant habit
  • 5. Good transportation ability and keeping quality
  • 6. Mid season flowering

DIFFERENCES BETWEEN THE NEW VARIETY ‘FISMARS 339’ AND A SIMILAR VARIETY

‘Fismars 339’ differs from ‘Fismars’ (U.S. Plant Pat.
