Botanical classification/cultivar designation: Petunia×hybrida cultivar USTUNI164.
The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name USTUNI164.
The new Petunia 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 disease-resistant and heat-tolerant Petunias with semi-upright plant habit and attractive flower colors.
The new Petunia originated from a cross-pollination made by the Inventor on May 6, 1998 of the Petunia cultivar Titan White, not patented, as the female, or seed parent, with an unnamed selection of Petunia, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny on Jun. 15, 1999 in Gensingen, Germany, on the basis of its plant habit and attractive flower coloration.
Asexual reproduction of the new cultivar by terminal vegetative cuttings since Jun. 25, 1999, taken in Gensingen, Germany has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
Plants of the cultivar USTUNI164 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USTUNI164’. These characteristics in combination distinguish ‘USTUNI164’ as a new and distinct cultivar:
In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Petunia differed from plants of the female parent, the cultivar Titan White, in the following characteristics:
In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Petunia flowered earlier and had larger flowers than plants of the male parent selection.
Plants of the new Petunia can be compared to plants of the cultivars Surfinia White, not patented, and Cascadia Choice, U.S. Plant Pat. No. 8,768. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Petunia differed primarily from plants of the cultivars Surfinia White and Cascadia Choice in flower size as plants of the new Petunia have large flowers than plants of the cultivars Surfinia White and Cascadia Choice.
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 Petunia.
The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘USTUNI164’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘USTUNI164’.
The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the early spring under full sun conditions with day temperatures ranging from about 18 to about 35° C. and night temperatures ranging from about 10 to about 21° C. After planting rooted cuttings, plants were grown for about eight weeks in 15-cm containers.
