plant named ‘J-1’

Abstract

A new cultivar of Calibrachoa plant named ‘J-1’ that is characterized by double red-purple flowers, vigorous growth and early flowering.

Description

Botanical classification: Calibrachoa sp.

Variety denomination: ‘J-1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant botanically known as Calibrachoa sp. and hereinafter referred to by the cultivar name ‘J-1’.

‘J-1’ is a naturally occurring branch mutation of a proprietary Calibrachoa cultivar ‘I-11’ (not patented). ‘J-1’ was discovered in a greenhouse in a cultivated area of Bnei-Zion, Israel in December of 2009.

Asexual reproduction first occurred when terminal cuttings of the new cultivar ‘J-1’ were propagated in December of 2009 in Bnei-Zion, Israel. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Calibrachoa cultivar ‘J-1’. These traits in combination distinguish ‘J-1’ as a new and distinct cultivar apart from other existing known varieties of Calibrachoa.

• • 1. Calibrachoa ‘J-1’ exhibits double red-purple flowers.
  • 2. Calibrachoa ‘J-1’ exhibits vigorous growth.
  • 3. Calibrachoa ‘J-1’ exhibits early flowering.

The closest comparison cultivar is the parent plant Calibrachoa ‘I-11’. The new cultivar ‘J-1’ is distinguishable from the parent Calibrachoa ‘I-11’ by the following characteristics:

• • 1. ‘J-1’ exhibits a large central flower whorl. The flowers of ‘I-11’ do not have a central flower whorl.
  • 2. ‘J-1’ exhibits lighter color flowers than ‘I-11’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Calibrachoa ‘J-1’. The plant in the photograph shows an overall view of a 3.5 month old plant.

The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Calibrachoa cultivar named ‘J-1’. Data was collected in Ben-Zion, Israel from 3.5 month plastic greenhouse grown plants in 12 cm containers. The time of year was Winter. The average temperature during the day was 22° Centigrade and 15° Centigrade at night. The average light level was 700 Lux. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘J-1’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
