plant named ‘Petdero’

Abstract

A new Petunia plant named ‘Petdero’ particularly distinguished by the large, bold red-purple flowers, good floriferousness, medium green foliage, early flowering with a good center flowering habit, and exceptional branching with outwardly spreading plant habit.

Description

Latin name of the genus and species of the plant claimed: Petunia hybrida.

Varietal denomination: ‘Petdero’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Petunia, botanically known as Petunia hybrida, and hereinafter referred to by the variety name ‘Petdero’.

‘Petdero’ is a product of a planned breeding program. The new cultivar has large, bold red-purple flowers, good floriferousness, medium green foliage, early flowering with a good center flowering habit, and exceptional branching with outwardly spreading plant habit.

‘Petdero’ originated from a hybridization made in August 2004 in a controlled breeding environment in Enkhuizen, Netherlands. The female parent was the proprietary, unpatented plant designated ‘D1314-1’, with dark rose flowers.

The male parent of ‘Petdero’ was the proprietary, unpatented plant designated ‘C1328-1’, with pink flowers. The resultant seed was sown in February 2005.

‘Petdero’ was selected as one flowering plant within the progeny of the stated cross in the May 2005 in a controlled environment in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘Petdero’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2005 in a controlled environment in Enkhuizen, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Petdero’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Petdero’ 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.

A Plant Breeder's Right for this cultivar was applied for in Canada on Feb. 9, 2010 (#10-6826). ‘Petdero’ has not been made publicly available more than one year prior to the filing of this application.

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 Petunia as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Petdero’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety and a close-up of the flowers growing in a 4 inch pot.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. from plants growing California from plants growing in a greenhouse trial in April 2010. These plants were approximately 13-14 weeks of age.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
