Petunia plant named ‘Kerprilcomp’

Abstract

A new and distinct cultivar of Petunia plant named ‘Kerprilcomp’, characterized by its compact and outwardly spreading to trailing growth habit; freely branching habit; freely flowering habit; double purple violet-colored flowers with darker purple venation; and good garden performance.

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Kerprilcomp’.

BACKGROUND OF THE INVENTION

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

The new Petunia is a product of a planned breeding program conducted by the Inventors in Over, Cambridge, United Kingdom. The objective of the breeding program is to create new Petunia cultivars with double and attractive flowers.

The new Petunia originated from a cross-pollination made by the Inventors on Aug. 15, 2001 in Over, Cambridge, United Kingdom of a proprietary selection of Petunia×hybrida identified as code number 01-45-14, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number 01-45-8, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Over, Cambridge, United Kingdom on May 30, 2002.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Over, Cambridge, United Kingdom since October, 2002, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Kerprilcomp has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Kerprilcomp’. These characteristics in combination distinguish ‘Kerprilcomp’ as a new and distinct cultivar of Petunia:

• • 1. Compact and outwardly spreading to trailing growth habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Double purple violet-colored flowers with darker purple venation.
  • 5. Good garden performance.

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

• • 1. Plants of the new Petunia are more trailing than and not as upright as plants of the female parent selection.
  • 2. Plants of the new Petunia have double flowers whereas plants of the female parent selection have single flowers.
  • 3. Plants of the new Petunia and the female parent selection differ in flower color.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in the flower color as plants of the male parent selection have magenta-colored flowers.

Plants of the new Petunia can also be compared to plants of the Petunia cultivar Kerpril, disclosed in U.S. Plant patent application Ser. No. 09/399,874 (not abandoned). In side-by-side comparisons conducted in Over, Cambridge, United Kingdom, plants of the new Petunia differed from plants of the cultivar Kerpril in the following characteristics:

• • 1. Plants of the new Petunia were more compact than plants of the cultivar Kerpril.
  • 2. Plants of the new Petunia flowered about three days earlier than plants of the cultivar Kerpril.
  • 3. Plants of the new Petunia had darker colored flowers than plants of the cultivar Kerpril.
  • 4. Plants of the new Petunia had longer peduncles than plants of the cultivar Kerpril.
