plant named ‘Daiichi Bluette Purple2’

Abstract

A new and distinct Petunia cultivar named ‘Daiichi Bluette Purple2’ is disclosed, characterized by distinctive vibrant purple flowers and a trailing plant habit. 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: ‘Daiichi Bluette Purple2’.

The new Petunia cultivar resulted as part of a planned breeding program by the inventors Jun Tsukahara, and Kuniyoshi Konishi, 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 2005. The new variety was discovered in November of 2007 by the inventors in a group of seedlings resulting from that crossing, in a commercial greenhouse in Yame, Fukuoka, Japan.

Asexual reproduction of the new cultivar ‘Daichi Bluette Purple2’ was first performed by vegetative cuttings at a commercial greenhouse in Yame, Fukuoka, Japan in January 2008. Subsequently many generations have been produced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Daiichi Bluette Purple2’ 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 ‘Daiichi Bluette Purple2’. These characteristics in combination distinguish ‘Daiichi Bluette Purple2’ as a new and distinct Petunia cultivar:

• • 1. Distinctive vibrant purple flowers.
  • 2. Trailing Plant Shape.

COMPARISON TO THE PARENT VARIETIES

Plants of the new cultivar ‘Daiichi Bluette Purple2’ are similar in most horticultural characteristics to plants of the unnamed proprietary seed parent. However, the seed parent has shorter calyx than the new cultivar. Additionally, the seed parent has a less trailing ing and taller plant form than ‘Daiichi Bluette Purple2’.

Plants of the new cultivar ‘Daiichi Bluette Purple2’ are similar in most horticultural characteristics to plants of the unnamed proprietary pollen parent. However, the pollen parent has a different petal form. Additionally, the pollen parent has a less trailing and shorter plant form than ‘Daiichi Bluette Purple2’.

COMPARISON TO COMMERCIAL VARIETIES

The new cultivar can be compared to the unpatented commercial variety ‘Bluette Purple’. ‘Daiichi Bluette Purple2’ is similar to this commercial variety in most horticultural characteristics, however, the new variety has an overall taller plant form, with longer stems and more creeping habit.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Daiichi Bluette Purple2’ grown in a greenhouse, in a 6 inch pot. Age of the plant photographed is approximately 12 weeks from a rooted cutting. 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.
