Abstract

A new and distinct cultivar of Alpinia plant named ‘LY1’ is disclosed characterized by robust plants with observed resistance to ginger blast. Inflorescences are long and composed of attractive pink flowers with yellow interior petaloids. Plants have a long flowering season, of nearly 8 months, with full-flowering from June to September in Guangdong Province, China. The new variety is useful as both a cut flower and landscape plant in warm climates.

Description

Latin name of the genus and species: Alpinia zerumbet x henryi.

Variety denomination: ‘LY1’.

BACKGROUND OF THE INVENTION

The new cultivar, Alpinia ‘LY1’, is the product of a planned breeding program. The intent of the breeding program was to produce new ornamental ginger varieties for both cut flower and landscape purposes with improved resistance to diseases and pests in hot, wet climates. The new variety originated from a cross pollination of an unpatented, unnamed seed parent, Alpinia zerumbet with the pollen parent an unpatented, unnamed variety of Alpinia henryi. The cross pollination was made during May of 2010 in Guangdong Province, China at a research nursery. The new cultivar ‘LY1’ was selected in December of 2013 at the same location.

Asexual reproduction of the new cultivar ‘LY1’ was first performed by division in Guangdong Province at a research nursery January of 2014. Alpinia ‘LY1’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘LY1’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environmentenvironmenE 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 ‘LY1’. These characteristics in combination distinguish ‘LY1’ as a new and distinct Alpinia cultivar:

- 1. Usefulness as both a cut flower and landscape plant in warm climates.
- 2. Strong plants resistant to typical diseases and pests found in warm climates.
- 3. Ornamental flowers with pink petals and yellow interior petaloids.
- 4. Long inflorescences.
- 5. Long flowering season, of nearly 8 months, with full-flowering from June to September in Guangdong Province, China.

PARENTAL COMPARISON

Plants of the new cultivar ‘LY1’ are similar to plants of the seed parent in most horticultural characteristics. However, plants of the new cultivar ‘LY1’ differ in the following:

- 1. Alpinia ‘LY1’ produces inflorescences of a brighter pink, with less flowers per inflorescence.
- 2. Alpinia ‘LY1’ produces flowers over a longer time, approximately 8 months.
- 3. Alpinia ‘LY1’ produces a smaller, lighter colored fruit than the seed parent.

Plants of the new cultivar ‘LY1’ are similar to the pollen parent in most horticultural characteristics. However, plants of the new cultivar ‘LY1’ differ in the following:

- 1. Alpinia ‘LY1’ produces longer inflorescences, which are more drooping than those of the pollen parent.
- 2. Plants of Alpinia ‘LY1’ are taller than plants of the pollen parent.
- 3. Alpinia ‘LY1’ produces darker colored fruit than the seed parent.

COMMERCIAL COMPARISON

The new cultivar ‘LY1’ can be compared to the unpatented commercial variety Alpinia zerumbet ‘Variegata’. Plants of the new cultivar ‘LY1’ differ in the following:

- 1. Plants of Alpinia ‘LY1’ are taller than plants of ‘Variegata’.
- 2. Flowers of Alpinia ‘LY1’ are brighter pink than flowers of ‘Variegata’.
- 3. Alpinia ‘LY1’ produces more inflorescences for cut flower purposes than ‘Variegata’.
- 4. Alpinia ‘LY1’ produces lighter colored fruit than ‘Varigata’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate in full color typical plants of ‘LY1’ grown outdoors, in the ground in Guangdong Province, China. The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of the new Alpinia plant. Temperatures ranged from approximately 2° C. to 38° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.
