plant named ‘PBLLV40-0’

Abstract

A new and distinct Petunia cultivar named ‘PBLLV40-0’ is disclosed, characterized by unique, fully double green-white flowers. 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: ‘PBLLV40-0’.

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 research greenhouse in Yame, Fukuoka, Japan.

Asexual reproduction of the new cultivar ‘PBLLV40-0’ by vegetative cuttings was first performed at a research greenhouse in Yame, Fukuoka, Japan in September 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 ‘PBLLV40-0’ 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 ‘PBLLV40-0.’ These characteristics in combination distinguish ‘PBLLV40-0’ as a new and distinct Petunia cultivar:

• • 1. Unique green-white colored double flower.
  • 2. Very compact growth habit
  • 3. High flower count.

COMPARISON TO THE PARENT VARIETIES

Plants of the new cultivar ‘PBLLV40-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary seed parent. However, the new cultivar produces a pale greenish yellow double flower whereas the seed parent produces a pale yellow single flower. Additionally, plants of new cultivar produces a larger flower and a shorter length stem compared to those of the seed parent.

Plants of the new cultivar ‘PBLLV40-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary pollen parent. However, plants of the pollen parent produce pale yellow colored flowers that are larger than the pale greenish yellow flowers of the new cultivar. The new cultivar also produces a longer peduncle 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. ‘PBLLV40-0’ is similar to this commercial variety in most horticultural characteristics, most specifically, in plant habit, however, plants of the new cultivar produce pale yellowish green colored flowers, whereas flower of ‘Daiichi Bluette Purple2’ bright reddish purple. Additionally the new cultivar produces a double flower form compared to the single flower form of ‘Daiichi Bluette Purple2’.

The new cultivar can be compared to the patented commercial variety ‘PDBVI35-0’, U.S. Plant Pat. No. 22,985. ‘PBLLV40-0’ is similar to this commercial variety in most horticultural characteristics, most specifically, in plant habit, and both varieties have unique double flowers. However, plants of the new cultivar produce pale yellowish green colored flowers, compared to the dark purple colored flowers of ‘PDBVI35-0’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PBLLV40-0’ grown in a greenhouse, in a 10 inch commercial basket. Age of the plant photographed is approximately 20 weeks from 5 rooted cuttings.

FIG. 2 illustrates a close up of the flowers.

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.
