‘Kerprilpro’

A new and distinct Petunia cultivar named ‘KERPRILPRO’ is disclosed, characterized by a dense, spreading growth habit, and attractive double violet flowers with darker violet veins. The plants flower freely and begin flowering under short day condition. The new variety is a Petunia, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Petunia atkinsiana.

Variety denomination: ‘KERPRILPRO’.

BACKGROUND OF THE INVENTION

‘KERPRILPRO’ is a product of a breeding and selection program for ornamental Petunia varieties to be vegetatively propagated. The new plant of the present invention comprises a new and distinct cultivar of Petunia plant.

‘KERPRILPRO’ is a seedling resulting from the crossing of an, unpatented proprietary Petunia atkinsiana referred to as ‘15-930-2’ with the pollen parent, an unpatented, proprietary, Petunia atkinsiana referred to as ‘15-930-6’, conducted in August 2015. The selection of the new variety was made in May 2016, by the inventor at a research greenhouse located in Cambridge, UK.

‘KERPRILPRO’ was first asexually reproduced by vegetative terminal cuttings at a research greenhouse in Cambridge, UK, September 2016. The new cultivar has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The cultivar ‘KERPRILPRO’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘KERPRILPRO’ These characteristics in combination distinguish ‘KERPRILPRO’ as a new and distinct Petunia cultivar:

    • 1. Attractive double flowers
    • 2. Day-length neutral flowering. Flower bud initiation occurs in day lengths of less than 8 hours.
    • 3. Spreading plant habit.
    • 4. Violet flower with dense, dark violet colored veins.
    • 5. Abundant flowering.
    • 6. Light floral fragrance.

PARENT COMPARISON

Plants of the new cultivar ‘KERPRILPRO’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘KERPRILPRO’ differ in the following:

    • 1. ‘KERPRILPRO’ flowers more abundantly than the seed parent.
    • 2. The new variety produces double flowers; the seed parent produces single flowers.
    • 3. The new variety has shorter lateral branches than the seed parent.

Plants of the new cultivar ‘KERPRILPRO’ are similar to plants of the pollen parent in most horticultural characteristics however, plants of the new cultivar ‘KERPRILPRO’ differ in the following:

    • 1. ‘KERPRILPRO’ is a low, spreading plant, the pollen parent has an upright habit.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KERPRILPRO’ can be compared to the commercial variety Petunia ‘Kerprilcomp’, U.S. Plant Pat. No. 19,327. These varieties are similar in most horticultural characteristics, having fully double flowers and distinctive dark flower veins. The new variety ‘KERPRILPRO’, however, differs in the following:

    • 1. ‘KERPRILPRO’ has a violet flower with dark violet veins, this comparator has a purple flower with dark purple veins.
    • 2. ‘KERPRILPRO’ flowers more abundantly than this comparator.
    • 3. ‘KERPRILPRO’ begins flowering earlier than this comparator.
    • 4. ‘KERPRILPRO’ produces more branches than this comparator.

Plants of the new cultivar ‘KERPRILPRO’ can also be compared to the commercial variety Petunia ‘Tumbelina Priscilla’, unpatented. These varieties are similar in most horticultural characteristics, having double flowers and compact plant forms. ‘KERPRILPRO’ however, differs in the following:

    • 1. ‘KERPRILPRO’ flowers more abundantly.
    • 2. ‘KERPRILPRO’ has a smaller flower.
    • 3. ‘KERPRILPRO’ has more petals in the flower.
    • 4. Tumbelina Priscilla has veins colored N82A; the new variety has veins colored Violet 86A and 86B.
    • 5. ‘KERPRILPRO’ has a more stable flower color.
    • 6. ‘KERPRILPRO’ flowers earlier and in short days.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘KERPRILPRO’ grown in a greenhouse, in Cambridge, United Kingdom.

FIG. 2 illustrates in full color a typical mature flower of ‘KERPRILPRO’ during Spring. Age of the plant photographed is approximately 90 days from a rooted cutting in a 20 cm basket.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
