USPP37136P2 - Aloe plant named ‘AMIAL2139’ - Google Patents

Abstract

A new and distinct Aloe plant named ‘AMIAL2139’ which is characterized by a rosette of succulent foliage that gives rise to an abundance of small, secondary rosettes which will eventually ring the entire primary rosette, foliage with an upright attitude, dark green foliage with a moderate abundance of light yellow-green, nearly white, oblong protuberances loosely arranged in highly irregular transverse rows on both the upper and lower leaf surfaces, dentate leaf margins with an abundance of spine-like teeth, and the stability of these characteristics from generation to generation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Aloe hybrida.

Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘AMIAL2139’.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIAL2139’ is a seedling selection resulting from the selected cross pollination of an unnamed interspecific Aloe rouhii x Aloe descoingsii hybrid plant (not patented), the seed parent, and an unnamed Aloe vera plant that typifies the species (not patented), the pollen parent. The crossing was made by the inventor in the spring of 2019 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the spring of 2020, one seedling was observed which exhibited erect dark green foliage with an abundance of oblong foliar protuberances, unlike the parent plants and all other progeny in the trials. Upon confirmation of distinctness and stability, ‘AMIAL2139’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL2139’, by way of rooting leaf cuttings, was first initiated in the summer of 2020 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through four subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIAL2139’ 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 ‘AMIAL2139’. These characteristics in combination distinguish ‘AMIAL2139’ as a new and distinct Aloe vera plant:

• • 1. ‘AMIAL2139’ exhibits a primary rosette of succulent foliage which gives rise to an abundance of small, secondary rosettes which will eventually ring the entire primary rosette with age; and
  • 2. ‘AMIAL2139’ exhibits dark green succulent foliage which is held upright and slightly outward; and
  • 3. ‘AMIAL2139’ exhibits dentate leaf margins with an abundance of spine-like teeth that are colored light greyed-green and lightly suffused with greyed-orange at their tips; and
  • 4. ‘AMIAL2139’ exhibits a moderate abundance of light yellow-green, nearly white, oblong protuberances loosely arranged in highly irregular transverse rows on both the upper and lower leaf surfaces.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘AMIAL2139’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 40 weeks old, shown planted in a 14 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, adaxial surface of the mature foliage ‘AMIAL2139’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the abaxial surface of the mature foliage of ‘AMIAL2139’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in October of 2020 describe averages from a sample set of six specimens of 40-week-old ‘AMIAL2139’ plants grown in 14 cm nursery containers at commercial greenhouse in Honselersdijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe which consisted of minimal overhead irrigation, minimal fertilizer applications, and control measures for common pests and diseases. No photoperiodic treatments or artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIAL2139’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, Sixth Edition.

A botanical description of ‘AMIAL2139’ and a comparison with the parent plants and the closest known commercial comparator is provided below.
