Poinsettia plant named ‘Fismars’

Abstract

A new and distinct Poinsettia plant named ‘Fismars’, characterized as having medium red bract color; medium sized bracts in tight and flat rosette-like arrangement; dark green foliage with weak lobes; about medium sized, V-shaped with the branches slanting upright; and begin of flowering mid season.

Description

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

Variety denomination: Fismars.

The present invention relates to a new and distinct cultivar of poinsettia plant known by the cultivar name ‘Fismars’, and botanically known as Euphorbia pulcherrima.

‘Fismars’ is a product of a planned breeding program which had the objective of creating new poinsettia cultivars with red flower color in combination with dark-green foliage and good cultivation ability. ‘Fismars’ originated from a hybridization made by the inventor, Katharina Zerr, in Hillscheid, Germany, in 1996.

The female parent is the poinsettia variety ‘490’ (U.S. Plant Pat. No. 7,825), which is characterized by red bract color, dark-green foliage, and early flowering. The male parent is a proprietary poinsettia cultivar, designated No. ‘298’ (unpatented), having bright red bracts, dark-green foliage, bracts and leaves with strong lobes, and upright plant habit with strong branch s.

The seeds germinated in the spring of 1997, and the resulting seedlings were selected during flowering period in the late summer of 1997. ‘Fismars’ was discovered and selected as a flowering plant within the progeny of the stated cross by Katharina Zerr. A cutting was taken from the seedling plant and grown out for examination of single-stem plants in the late fall to winter of 1997/98.

In the spring of 1999, more cuttings were taken from the chosen seedling and grafted on rootstocks of ‘Beckmann's Altrosa’, U.S. Plant Pat. No. 9,336, in order to enhance branching ability. From the upper area of the successfully grafted plants, shoot tip cuttings were taken for the cultivation of branched plants for the second examination in the fall of 1999.

Horticultural examination (of the clone) starting in 1999 and continuing thereafter has confirmed that the combination of characteristics as herein disclosed for ‘Fismars’ are firmly fixed and retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fismars’ which in combination distinguish this Poinsettia as a new and distinct cultivar:

1. Medium red bract color;

2. Medium siz d bracts in tight and flat rosette-like arrangem nt;

3. Dark green foliag with w ak lobes;

4. About medium sized, v-shaped with the branches slanting upright; and

5. Begin of flowering mid season

‘Fismars’ 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. The following observations, measurements and comparisons describe plants grown in Hillscheid, Germany, under greenhouse conditions which approximate those generally used in commercial practice.

Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fismars’ is the parent cultivar ‘490’ and the variety ‘Fiscor’ (U.S. Plant Pat. No. 9,364).

In comparison to parent cultivar ‘490’ also known as ‘Freedom Red’, ‘Fismars’ has smaller bracts with very little rugosity, leaves with only weak expression of lobes, more uniform plant habit with more upright directed branches, and medium, instead of early, beginning of flowering.

In comparison to ‘Fiscor’, ‘Fismars’ has a slightly less intense bract color, less distinct lobing of bracts and leaves, and similar plant size, but different habit: it is less wide, more V-shaped, which means an advantage for packing and shipment.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic drawing shows typical inflorescence and foliage of ‘Fismars’, with colors being as true as possible with illustrations of this type. The photograph shows a mature potted plant.

DETAILED BOTANICAL DESCRIPTION

The plants described had been grown in a greenhouse in Dorsten, Germany, from summer to fall of 2002. Rooted cuttings were planted into 13 cm pots on July 17, and were pinched on August 1, leaving 7-8 leaves. Initially, the temperature was between a minimum of 20° C. and 26° C. maximum (ventilation temperature), and lower from late September, minimum 18° C. to 24° C. maximum. Growth regulator was applied twice, in early and in late August. The plants initiated flowers under short-day conditions under natural short-day conditions in fall, no black cloth was applied.

Observations and measurements were mainly taken in early December, when the plants were in full flower and about 20 weeks old. In the following description color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined indoors in a north light.
