Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCALI402-1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘USCALI402-1’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to create new Calibrachoa cultivars with uniform plant habit and attractive flowers.

The new Calibrachoa originated from a cross-pollination made by the Inventor on Apr. 20, 2004 in Hikone, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code number CJ04-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number CJ04-09, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany on May 24, 2005.

Asexual reproduction of the new Calibrachoa by terminal cuttings in a controlled environment in Gensingen, Germany since May 25, 2005 has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar USCALI402-1 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperatures, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USCALI402-1’. These characteristics in combination distinguish ‘USCALI402-1’ as a new and distinct cultivar of Calibrachoa:

    • 1. Compact, mounding and outwardly spreading growth habit.
    • 2. Numerous pale yellow-colored flowers.
    • 3. Resistant to Thielaviopsis.
    • 4. Good garden performance.

The new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Calibrachoa are not as upright as plants of the female parent selection.
    • 2. Plants of the new Calibrachoa are more freely branching than plants of the female parent selection.

Plants of the new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Calibrachoa are more upright than plants of the male parent selection.
    • 2. Plants of the new Calibrachoa have larger flowers than plants of the male parent selection.

Plants of the new Calibrachoa can be compared to plants of the cultivar Sunbelki, disclosed in U.S. Plant Pat. No. 11,558. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa differed from plants of the cultivar Sunbelki in the following characteristics:

    • 1. Plants of the new Calibrachoa flowered earlier than plants of the cultivar Sunbelki.
    • 2. Plants of the new Calibrachoa and the cultivar Sunbelki differed in flower color as plants of the cultivar Sunbelki had yellow-colored flowers.
    • 3. Plants of the new Calibrachoa were observed to be resistant to Thielaviopsis whereas plants of the cultivar Sunbelki were observed to susceptible to Thielaviopsis.

Plants of the new Calibrachoa can also be compared to plants of the cultivar KLECA05104, not patented. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa differed from plants of the cultivar KLECA05104 in the following characteristics:

    • 1. Plants of the new Calibrachoa were more compact and upright than plants of the cultivar KLECA05104.
    • 2. Plants of the new Calibrachoa were more freely branching than plants of the cultivar KLECA05104.
    • 3. Plants of the new Calibrachoa and the cultivar KLECA05104 differed in flower color as plants of the cultivar KLECA05104 had lemon Yellow-colored flowers.
