Abstract

A new and distinct Lagerstroemia cultivar named ‘DABLAGEO1’ is disclosed, characterized by early blooming, and observed mildew resistance. Plants flower prolifically, producing bright red-purple flowers. The new variety is a Lagerstroemia, normally used for outdoor ornamental purposes.

Description

Latin name of the genus and species: Lagerstroemia indica.

Variety denomination: ‘DABLAGE01’.

BACKGROUND OF THE INVENTION

The new Lagerstroemia cultivar is a product of a planned breeding program conducted by the inventor, Alain Dabadie, in Hagemau, France. The objective of the breeding program was to develop Lagerstroemia cultivars exhibiting the characteristics of early, abundant flowering and mildew resistance. The open pollination resulting in this new variety was made during August of 2010.

The seed parent is the unpatented commercial variety referred to as Lagerstroemia ‘Houston’. The pollen parent is unknown. The new variety was selected September of 2011 by the inventor in a group of seedlings resulting from the 2009 open pollination, in a seedling trial field in Landes, France.

Asexual reproduction of the new cultivar was performed by softwood cuttings. This was first performed at a commercial nursery in Landes, France during February of 2011 and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DABLAGE01’ 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 ‘DABLAGE01’ These characteristics in combination distinguish ‘DABLAGE01’ as a new and distinct Lagerstroemia cultivar;

- 1. Bright red-purple flowers.
- 2. Prolific flowering.
- 3. Early blooming.
- 4. Resistance to mildew.

Plants of the new cultivar ‘DABLAGE01’ are similar to plants of the seed parent in most horticultural characteristics; however, plants of the new cultivar ‘DABLAGE01’ differ in the following;

- 1. The new variety has a brighter pink colored flower.
- 2. The new variety produces inflorescences approximately 16 to 30 cm long, compared to the 10 to 16 cm inflorescences of the parent variety.
- 3. The new variety has resistance to mildew, the seed parent has not been observed to have resistance under same cultural conditions.
- 4. The new variety begins flowering mid-June to early July, under the same conditions the parent variety begins flowering mid-July.

The pollen parent cannot be identified.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DABLAGE01’ are comparable to the commercial variety Lagerstroemia ‘Pecos’, unpatented. The two Lagerstroemia varieties are similar in most horticultural characteristics, including observed mildew resistance, however, the new variety ‘DABLAGEO1’ differs in the following;

- 1. The new variety has a brighter pink flower.
- 2. New variety produces longer inflorescences.
- 3. New variety has a more weeping habit than the fully upright habit of ‘Pecos’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates, in full color, a typical grafted form of weeping standard plant habit of ‘DABLAGE01’ grown outdoors in Landes, France in the ground. The rootstock is an unnamed Lagerstroemia indica. Age of the plant photographed is approximately 5 years old from a rooted cutting.

FIG. 2 illustrates a close up view 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.

DETAILED BOTANICAL DESCRIPTION
