USPP20714P2 - Mandevilla plant named ‘Fisrix Dered’ - Google Patents

Abstract

A new Mandevilla plant named ‘Fisrix Dered,’ particularly distinguished by deep red, medium sized flowers, floriferous habit, medium green, glossy leaves, very good branching ability and moderately vigorous, medium to tall, bushy plant habit.

Description

Latin name of the genus and species of the plant claimed: Mandevilla sanderi (Hemsl.) Woodson.

Varietal denomination: ‘Fisrix Dered’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Mandevilla, botanically known as Mandevilla sanderi, and hereinafter referred to by the variety name ‘Fisrix Dered.’

‘Fisrix Dered’ is a product of a planned breeding program. The new cultivar ‘Fisrix Dered’ has deep red colored flowers, is early flowering and floriferous, and has very good branching characteristics.

‘Fisrix Dered’ originated from a hybridization made in the summer of 2003 in Hillscheid, Germany. The female parent is the commercial Mandevilla variety offered as ‘Sundaville’® Red, ‘Moulin Rouge’ in France, which is identical to ‘Sunmandecrim,’ U.S. Plant Pat. No. 15,539, having red flower color, good branching characteristics, and medium green to grass green foliage. The male parent is the commercial Mandevilla variety offered as‘My Fair Lady’™ and patented as ‘Helle,’ U.S. Plant Pat. No. 9,117, with white to pale pink flower color, deep green foliage, and relatively few branches.

The seeds produced by the hybridization were sown in the fall of 2003. The resulting seedlings (plants) were evaluated in late summer to fall of 2004. ‘Fisrix Dered’ was selected as one flowering plant in a greenhouse in Hillscheid, Germany.

The plant has been asexually reproduced for the first time in the fall of 2004 and it has been propagated repeatedly by vegetative cuttings in Hillscheid, Germany over a 2–3 year period. Horticultural examination of plants grown from cuttings of the plant initiated in Hillscheid, Germany, in the spring of 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisrix Dered’ are firmly fixed and are retained through successive generations of asexual reproduction.

Plant Breeder's Rights for this cultivar were applied for in European on Dec. 13, 2006 and in Canada on Jan. 28, 2008. ‘Fisrix Dered’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF THE PHOTOGRAPH

This new Mandevilla plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant in full color. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

The photograph is of a 10 month old plant grown in a greenhouse from the late summer of 2006 to early summer of 2007.

The second photograph shows a flower and a bud.

DETAILED BOTANICAL DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘Fisrix Dered.’ The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken in early June 2007 on 9 month old plants grown in 12 cm diameter pots in a glass-covered greenhouse.

Color readings were taken under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition). Texture description details were observed under a magnifying glass.

BRIEF SUMMARY OF INVENTION

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

• • 1. Deep red colored, medium sized flowers
  • 2. Floriferous, and inflorescences with relatively many flowers
  • 3. Medium green, glossy foliage, ovate leaves
  • 4. Moderately vigorous growth with very good branching characteristics
  • 5. Relatively upright, medium to tall plant habit

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fisrix Dered’ differs from the female parent, Mandevilla plant ‘Sunmandecrim’ U.S. Plant Pat. No. 15,539, in that ‘Fisrix Dered’ has a somewhat deeper red overall flower color, and especially a deeper and more uniformly red of the flower funnel, while ‘Sunmandecrim’ shows cherry to pink funnel color. Additionally, ‘Fisrix Dered’ has a more upright plant habit, and somewhat wider leaves.

‘Fisrix Dered’ differs from the male parent, the commercial Mandevilla plant ‘Helle’ U.S. Plant Pat. No. 9,117, in that ‘Fisrix Dered’ has a different flower color (red in contrast to pale pink to white) and is more freely branching.

‘Fisrix Dered’ differs from the commercial cultivar ‘Red Riding Hood’ (unpatented) in that ‘Fisrix Dered’ has a deeper red overall flower color, somewhat less green foliage and develops a higher number of branches.
