plant named ‘PBLYG39-0’

Abstract

A new and distinct Petunia cultivar named ‘PBLYG39-0’ is disclosed, characterized by a unique flower color of yellow with a soft pink margin, compact plants and abundant flowering. The new variety is a Petunia, suitable as an outdoor garden or container plant.

Description

Latin name of the genus and species: Petunia hybrid.

Variety denomination: ‘PBLYG39-0’.

The new Petunia cultivar resulted as part of a planned breeding program by the inventor Jun Tsukahara, in Yame, Fukuoka, Japan. The objective of the breeding program was to develop new Petunia varieties with interesting colors and attractive plant forms.

The new variety resulted from the crossing of the seed parent, an unnamed, unpatented proprietary Petunia seedling with the pollen parent, an unnamed, unpatented proprietary Petunia seedling in September of 2008. The new variety was discovered in May of 2009 by the inventor in a group of seedlings resulting from that crossing, in a commercial greenhouse in Yame, Fukuoka, Japan.

Asexual reproduction of the new cultivar ‘PBLYG39-0’ by vegetative cuttings was first performed at a commercial greenhouse in Yame, Fukuoka, Japan in May of 2009. Subsequently one generation has been produced and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PBLYG39-0’ has not 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 ‘PBLYG39-0.’ These characteristics in combination distinguish ‘PBLYG39-0’ as a new and distinct Petunia cultivar:

• • 1. Unique flower color with a yellow center and soft pink colored margins.
  • 2. Very compact plant habit.
  • 3. Abundant flowering.

COMPARISON TO THE PARENT VARIETIES

Plants of the new cultivar ‘PBLYG39-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary seed parent. However, the new cultivar has a compact plant habit and smaller plants size compared to the creeping plant habit of the seed parent. Additionally, plants of the seed parent produce lavender with yellow eye colored flowers, whereas ‘PBLYG39-0’ produces flowers that are pink with yellow eye.

Plants of the new cultivar ‘PBLYG39-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary pollen parent. However, the pollen parent produces pale yellow colored double flowers, whereas the new variety produces flowers that are pink with a yellow eye. Additionally, the new variety produces smaller flowers than the pollen parent.

COMPARISON TO COMMERCIAL VARIETIES

The new cultivar can be compared to the patented commercial variety ‘Daiichi Bluette Purple2’ U.S. Plant Pat. No. 22,236. ‘PBLYG39-0’ is similar to this commercial variety in most horticultural characteristics, most specifically, in plant habit, however, plants of the new cultivar produce pink flowers with a yellow center, compared to the solid red-purple flowers of ‘Daiichi Bluette Purple2’.

The new cultivar can be compared to the patented commercial variety ‘Bluette Gradation Pink’ U.S. Plant Pat. No. 22,237. ‘PBLRS38-0’ is similar to this commercial variety in most horticultural characteristics, however, plants of the new cultivar are most compact. Additionally the new cultivar produces a larger flowers, with a softer pink outer margin coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical flowers and foliage of ‘PBLYG39-0’.

FIG. 2 illustrates a close up of the flowers of ‘PBLYG39-0’ grown in a greenhouse, in a 10 inch commercial basket. Age of the plant photographed is approximately 20 weeks from 5 rooted cuttings.

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.
