USPP19218P2 - Petunia plant named ‘Whip Briink’ - Google Patents

Abstract

A new petunia plant particularly distinguished by bright pink flowers, compact plant habit with vigorous growth, and an initially spreading, upright plant habit, is disclosed.

Description

Genus and species: Petunia hybrida.

Variety denomination: ‘Whip Briink’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of petunia, botanically known as a Petunia hybrida,and hereinafter referred to by the cultivar name ‘Whip Briink’. The new cultivar originated from a hybridization made in August 2002 in Gilroy, Calif. The female parent was ‘1092-1’, a pink-flowered proprietary petunia plant (unpatented), while the male parent was ‘Conbloss’, a white-flowered petunia plant (U.S. Plant Pat. No. 13,556). The seeds produced by the hybridization were sown in February 2003. A single plant selection was chosen for further evaluation and for asexual propagation in April 2003.

The new cultivar was created in 2002 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a three and a half year period. The plant has also been trialed at Gilroy, Calif., Hillscheid, Germany and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights were applied for in Europe in November 2006.

SUMMARY OF THE INVENTION

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

• • 1. Bright pink flowers;
  • 2. Compact plant habit;
  • 3. Vigorous growth; and
  • 4. An initially spreading plant habit;

DESCRIPTION OF PHOTOGRAPHS

This new petunia plant is illustrated by the accompanying photographs which show the 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 photographs are of a 20-week old plant grown in a greenhouse in Hillscheid, Germany during the summer months.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Whip Briink’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 12-to-15-week-old plants which were planted as rooted cuttings in 4-inch pots in the early spring in a greenhouse trial setting. The plants had one plant growth regulator treatment and one terminal pinch after cuttings were transplanted. Color readings were taken under natural light in the greenhouse in March. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001). Texture description data was viewed with a dissecting microscope.
