Calibrachoa plant named ‘01C-J-4’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘01C-J-4’, characterized by its semi-prostrate, low mounding and outwardly spreading plant habit; freely branching growth habit; freely flowering habit; golden yellow-colored flowers with red-colored speckling and rust-colored venation; and good weather tolerance.

Description

Botanical classification/cultivar designation: Calibrachoa sp. cultivar 01C-J-4.

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 name ‘01C-J-4’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventors in Tochigi-ken, Japan. The objective of the breeding program is to create new early-flowering Calibrachoa cultivars that have stronger growth habit and attractive flower coloration.

The new Calibrachoa originated from a cross-pollination made by the Inventors in the Autumn of 2000, in Tochigi-ken, Japan, of the Calibrachoa cultivar Sunbelki, disclosed in U.S. Plant Pat. No. 11,558, as the female, or seed, parent with a proprietary Calibrachoa selection identified as code number 99-2-3, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Tochigi-ken, Japan, on Jun. 10, 2001. The selection of this plant was based on its strong plant growth habit and attractive flower coloration.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Tochigi-ken, Japan, since Aug. 10, 2001, 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 01C-J-4 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘01C-J-4’. These characteristics in combination distinguish ‘01C-J-4’ as a new and distinct cultivar of Calibrachoa:

• • 1. Semi-prostrate, low mounding and outwardly spreading plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Golden yellow-colored flowers with red-colored speckling and rust-colored venation.
  • 5. Good weather tolerance; tolerant to wind, rain, and low and high temperatures.

Plants of the new Calibrachoa are most similar to plants of the female parent, the cultivar Sunbelki. In side-by-side comparisons conducted by the Inventors in Tochigi-ken, Japan, plants of the new Calibrachoa differed from plants of the cultivar Sunbelki in the flowering characteristics:

• • 1. Plants of the new Calibrachoa were not as prostrate in plant habit as plants of the cultivar Sunbelki.
  • 2. Plants of the new Calibrachoa had smaller flowers than plants of the cultivar Sunbelki.
  • 3. Plants of the new Calibrachoa flowered later than plants of the cultivar Sunbelki.
  • 4. Plants of the new Calibrachoa and the cultivar Sunbelki differed in flower coloration as plants of the cultivar Sunbelki had light yellow-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the male parent selection. In side-by-side comparisons conducted by the Inventors in Tochigi-ken, Japan, plants of the new Calibrachoa differed from plants of the male parent selection in the flowering characteristics:

• • 1. Plants of the new Calibrachoa were more freely flowering than plants of the male parent selection.
  • 2. Plants of the new Calibrachoa and the male parent selection differed in flower coloration as plants of the male parent selection had dark yellow-colored flowers.

Compared to plants of the cultivar 01C-J-6, disclosed in a U.S. Plant patent application Ser. No. 10/919,012, plants of the new Calibrachoa flower later and differ in flower coloration.

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 one-gallon containers were used for the aforementioned photographs and the following description. Plants were grown under conditions which closely approximate commercial production conditions during the spring in Santa Paula, Calif. in a polyethylene-covered greenhouse. Plants were about five months old when the photographs and description were taken. During the production period, day temperatures ranged from 16 to 29° C., night temperatures ranged from 4 to 13° C., and maximum light levels ranged from 3,000 to 6,000 footcandles.
