USPP18866P3 - Poinsettia plant named ‘Fismars Pink’ - Google Patents

Abstract

A new Poinsettia plant particularly distinguished by medium size, pink, ovate bracts in a flat, rosette-like arrangement, with deep green foliage, ovate leaves with nearly no lobes, early to medium flowering response and a medium size, V-shape plant habit, is disclosed.

Description

Genus and species: Euphorbia pulcherrima.

Variety denomination: ‘Fismars Pink’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of poinsettia plant, botanically known as Euphorbia pulcherrima, and hereinafter referred to by the cultivar name ‘Fismars Pink’. The new cultivar is the result of an induced mutation in the poinsettia plant ‘Fismars’ (U.S. Plant Pat. No. 14,977) made in the year 2003 in Ahrensburg, Germany.

In May 2003, young plants of ‘Fismars’ were irradiated with x-rays in Ahrensburg, Germany. The treated plants were grown in Hillscheid, Germany, and were propagated by shoot tip cuttings. The resulting plants were screened for positive mutations and examined during the flowering period in winter 2003/2004. Among these plants a pink-flowered plant was selected and asexually multiplied for further examination in 2004.

The new cultivar was created in 2003 in Ahrensburg, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Hillscheid, Germany over a two-year period. ‘Fismars Pink’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Europe on Feb. 16, 2004 and in Canada on Nov. 17, 2004.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Hillscheid, Germany.

• • 1. Pink bract color;
  • 2. Medium size, ovate bracts in a flat, rosette-like arrangement;
  • 3. Deep green foliage with ovate leaves that have nearly no lobes;
  • 4. Medium size, V-shaped plant habit; and
  • 5. An early to medium flowering response.

DESCRIPTION OF PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying photograph which shows overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a whole plant about 18-weeks old and in full flower, grown in a greenhouse in Hillscheid, Germany, in early December of 2005.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Fismars Pink’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 18-week old plants which were planted as rooted cuttings in 14-cm pots on Jul. 28, 2005 and were pinched on Aug. 12, 2005, which left 7 to 8 leaves remaining. The plants were grown in a greenhouse at a minimum temperature of 18° C. and a ventilation temperature of 24° C. The plants initiated flowers under natural short-day conditions in fall. No black cloth was applied to the greenhouse to simulate short-day conditions. No growth regulator was applied. Color readings were taken under natural light in the greenhouse. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fismars Pink’ differs from the parental cultivar ‘Fismars’ (U.S. Plant Pat. No. 14,997) by having pink instead of red bract color and a more compact plant habit than ‘Fismars’.

‘Fismars Pink’ differs from the commercial cultivar ‘Fiscorosa’ (U.S. Plant Pat. No. 10,077), by having shorter bracts, inflorescences with fewer cyathia and a more compact plant habit than ‘Fiscorosa’.

‘Fismars Pink’ differs from the commercial cultivar ‘Eckalbert’ (U.S. Plant Patent applied for) by having flatter inflorescences with shorter and more horizontally directed bracts while ‘Eckalbert’ has more funnel-shaped inflorescences. In addition, the leaves and bracts of ‘Fismars Pink’ develop nearly no lobes, while ‘Eckalbert’ shows a moderate oak leaf shape. ‘Fismars Pink’ also has a later flowering response of 4 to 8 days compared to ‘Eckalbert’.
