Description

Latin name of genus and species of plant claimed: Petunia×hybrida.

Variety denomination: ‘Kersamfan’.

BACKGROUND OF THE INVENTION

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 ‘Kersamfan’.

The new cultivar originated in a controlled breeding program in Cambridge, United Kingdom during August 2001. The objective of the breeding program was the development of Petunia cultivars having single-type flowers with unique flower colors and vigorous, mounded, and trailing growth habit.

The female (seed) parent of the new cultivar was the proprietary Petunia×hybrida breeding selection designated 01-120-1, not patented, characterized by its single-type, pink flushed white-colored flowers and upright growth habit. The male (pollen) parent of the new cultivar was ‘Kercan’, U.S. Plant Pat. No. 13,787, characterized by its double-type, pink-colored flowers with deep pink-colored veins and semi-trailing growth habit. The new Petunia was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination during May 2002 in a controlled environment at Cambridge, United Kingdom.

Asexual reproduction of the new cultivar by terminal stem cuttings since May 2002 at Cambridge, United Kingdom and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Kersamfan’ as a new and distinct cultivar of Petunia plant:

    • 1. Salmon-colored flowers with deep salmon-colored veins;
    • 2. Large single-type flowers;
    • 3. Excellent branching; and
    • 4. Semi-trailing growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and growth habit and from plants of the male parent primarily in flower color and flower type.

Of the many commercially available Petunia cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Kercofan’, unpatented. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Kercofan’ in the following characteristics:

    • 1. Plants of the new cultivar have a flower color different from plants of ‘Kercofan’; and
    • 2. Plants of the new cultivar have more prominent flower petal venation than plants of ‘Kercofan’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Kersamfan’. The plants were grown 3 plants per pot in 20 cm pots for 10 weeks in a greenhouse at Cambridge, United Kingdom.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Kersamfan’.

FIG. 2 illustrates a close-up view of an individual flower of ‘Kersamfan’.

 DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where general color terms of ordinary significance are used. The color values were determined on Jun. 30, 2005 between 3:00 p.m. and 4:00 p.m. under 50% shade light conditions, in Cambridge, United Kingdom.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at Cambridge, United Kingdom 3 plants in each 20 cm pot for 10 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 64° F. to 82° F. (18° C. to 28° C.) during the day and approximately 57° F. to 68° F. (14° C. to 20° C.) during the night. Greenhouse light levels of an average of 4,645 footcandles were maintained during the day.
