Calibrachoa plant named ‘CBRZ0034’

Abstract

A new Calibrachoa plant named ‘CBRZ0034’ particularly distinguished by large red flowers with a thin dark red ring at the throat of the flower. The throat is yellow inside the flower at the base of the petals. The plant has large flowers, green foliage, good branching, semi-trailing plant habit, and has little sensitivity to soil pH.

Description

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

Varietal denomination: ‘CBRZ0034’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Calibrachoa, botanically known as Calibrachoa hybrida, and hereinafter referred to by the variety name ‘CBRZ0034’.

‘CBRZ0034’ is a product of a planned breeding program. The new cultivar has large red flowers with a thin dark red ring at the throat of the flower. The throat is yellow inside the flower at the base of the petals. The plant has large flowers, green foliage, good branching, semi-trailing plant habit, and has little sensitivity to soil pH.

‘CBRZ0034’ originated from a hybridization made in February 2015 in a greenhouse in Gilroy, Calif., USA. The female parent was a yellow flower selection made in a breeding population and is identified as ‘CASB0116-1’. The male parent of ‘CBRZ0034’ was an unpatented proprietary plant with red without a dark ring at the throat of the corolla and a smaller flower, known as ‘3053-1’ originating from a seedling selected in Gilroy, Calif.

The resulting seeds were sown in August 2015 and ‘CBRZ0034’ was selected as one flowering plant within the progeny of the stated cross in November 2015 in a controlled environment in Gilroy, Calif.

The first act of asexual reproduction of ‘CBRZ0034’ was accomplished when vegetative stem cuttings were propagated from the initial selection in the winter of 2015 in a controlled environment in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2016, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CBRZ0034’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CBRZ0034’ 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 has not yet been applied for. ‘CBRZ0034’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘CBRZ0034’ directly from the inventor.

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 Calibrachoa as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘CBRZ0034’ with colors being as true as possible with an illustration of this type. The photographic drawings show in FIG. 1. a close-up of the flowers and in FIG. 2. a flowering plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in the greenhouse in Gilroy in February 2019.

The measurements and observations were made in February 2019 in Gilroy, Calif. on plants grown in 4 inch pots in the greenhouse.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2015.
