CROSS-REFERENCE TO A RELATED APPLICATION AND STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

This application claims priority to a Canadian Plant Breeders' Rights application filed on May 17, 2019, application number 19-9877. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed Plant Breeder's Rights documents.

The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia X hybrida and hereinafter referred to by the name ‘BBTUN91601M2’.

The new Petunia plant is a naturally-occurring branch mutation of Petunia X hybrida ‘USTUN91601’, disclosed in U.S. Plant Pat. No. 29,663. The new Petunia plant was discovered by the Inventor on a single flowering plant from within a population of plants of ‘BBTUN91601’ in a controlled greenhouse environment in Carleton, Mich. on Aug. 15, 2017.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Carleton, Mich. since Aug. 15, 2017 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘BBTUN91601M2’. These characteristics in combination distinguish ‘BBTUN91601M2’ as a new and distinct Petunia plant:

• • 1. Upright to outwardly spreading and mounding to eventually trailing plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit; dense and bushy plant form.
  • 4. Early and freely flowering habit.
  • 5. Dark red purple and white bi-colored flowers.
  • 6. Excellent garden performance.

Plants of the new Petunia can be compared to plants of the mutation parent, ‘USTUN91601’. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUN91601’ in plant and growth habit as plants of the new Petunia are more freely branching, denser and more uniformly mounding than plants of ‘USTUN91601’.

Plants of the new Petunia can be compared to plants of ‘Kakegawa S36’, disclosed in U.S. Plant Pat. No. 14,037. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Kakegawa S36’ in the following characteristics:

• • 1. Plants of the new Petunia are more mounding than and not as trailing as plants of ‘Kakegawa S36’.
  • 2. Plants of the new Petunia flower earlier than plants of ‘Kakegawa S36’.
  • 3. Plants of the new Petunia and ‘Kakegawa S36’ differ in flower color as plants of the new Petunia have dark red purple and white bi-colored flowers whereas plants of ‘Kakegawa S36’ have solid magenta-colored flowers.
  • 4. Plants of the new Petunia have improved pathogen tolerance than plants of ‘Kakegawa S36’.

Plants of the new Petunia can also be compared to plants of ‘KL 1117’, disclosed in U.S. Plant Pat. No. 25,485. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘KL 1117’ in the following characteristics:

• • 1. Plants of the new Petunia are more mounding than and not as trailing as plants of ‘KL 1117’.
  • 2. Plants of the new Petunia flower earlier than plants of ‘KL 1117’.
  • 3. Plants of the new Petunia and ‘KL 1117’ differ in flower color as plants of the new Petunia have dark red purple and white bi-colored flowers whereas plants of ‘KL 1117’ have white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Petunia plant 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 Petunia plant.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘BBTUN91601M2’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘BBTUN91601M2’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken.
