Abstract

A new and distinct cultivar of Calibrachoa plant named ‘USCALI17’, characterized by its semi-upright plant habit; freely branching habit; freely flowering habit; large red purple-colored flowers; good weather tolerance; and resistance to Thielaviopsis.

Description

Botanical classification/cultivar designation: Calibrachoa sp. cultivar USCALI17.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related applications: Calibrachoa Plant Named ‘USCALI48’ (U.S. Plant patent application Ser. No. 10/827,541) and Calibrachoa Plant Named ‘USCALI4’ (U.S. Plant patent application Ser. No. 10/827,545).

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 ‘USCALI17’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the program is to create new heat-tolerant and disease-resistant Calibrachoa cultivars with desirable plant habit and attractive flower colors.

The new Calibrachoa originated from a cross-pollination made by the Inventor on May 10, 1998 of a proprietary seedling selection of Calibrachoa identified as code number CJ20-7, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa identified as code number CJ19-2, not patented, as the male, or pollen, parent. The new Calibrachoa was selected by the Inventor on Jun. 15, 1999 in a controlled environment in Gensingen, Germany.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Gensingen, Germany since Jun. 25, 1999, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar USCALI17 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, water status and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USCALI17’. These characteristics in combination distinguish ‘USCALI17’ as a new and distinct cultivar of Calibrachoa:

    • 1. Semi-upright to eventually cascading plant habit.
    • 2. Freely branching habit.
    • 3. Freely flowering habit.
    • 4. Large red purple-colored flowers.
    • 5. Good weather tolerance; tolerant to rain and low and high temperatures.
    • 6. Resistant to Thielaviopsis.

Plants of the new Calibrachoa differ primarily from plants of the parent selections in plant habit as plants of the female selection are more upright than plants of the new Calibrachoa and plants of the male parent are more creeping than plants of the new Calibrachoa.

Plants of the new Calibrachoa can be compared to plants of the cultivar Million Bells Trailing Pink, U.S. Plant Pat. No. 10,287. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa had a more upright plant habit than plants of the cultivar Million Bells Trailing Pink. In addition, plants of the new Calibrachoa and the cultivar Million Bells Trailing Pink differed in flower color.

Plants of the new Calibrachoa can also be compared to plants of the cultivar Colorburst Pink, not patented. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa had a more upright plant habit than plants of the cultivar Colorburst Pink. In addition, plants of the new Calibrachoa and the cultivar Colorburst Pink differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘USCALI17’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of ‘USCALI17’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 15-cm containers for about five weeks were used for the aforementioned photographs and following description. Plants were grown under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Bonsall, Calif. During the production period, day temperatures ranged from 18 to 35° C. and night temperatures ranged from 7 to 18° C.
