USPP36929P2 - Aloe plant named ‘AMIAL2136’ - Google Patents

Abstract

A new and distinct variety of Aloe plant named ‘AMIAL2136’ which is characterized by succulent foliage arranged in a basal rosette and held upright to outward, dark green lanceolate foliage with spine-like teeth evenly spaced along the margins, mature foliage in the lower whorls of the rosette which are sparsely to moderately covered with small orbicular protuberances arranged in irregular longitudinal rows on the abaxial surface, 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 A. vera x A. arborescens.

Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘AMIAL2136’.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIAL2136’ is a seedling selection resulting from the controlled pollination of an unnamed Aloe vera plant (unpatented), the seed parent, and an unnamed Aloe arborescens plant (unpatented), 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 that was observed exhibited an abundance of small light yellow-green orbicular protuberances loosely arranged in irregular longitudinal rows on the abaxial surface the dark green foliage when compared to the parent plants and all other progenies. The mutation was noted for its unique foliage color and growth habit and was subsequently isolated for further evaluation to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘AMIAL2136’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL2136’, 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 five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIAL2136’ 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 ‘AMIAL2136’. These characteristics in combination distinguish ‘AMIAL2136’ as a new and distinct Aloe vera plant:

• • 1. ‘AMIAL2136’ exhibits a large rosette of succulent foliage which gives rise to a plurality of secondary rosettes as the plant ages; and
  • 2. ‘AMIAL2136’ exhibits dark green succulent foliage which is held upright and slightly outward, with the distalmost portions of laminas curled outward; and
  • 3. ‘AMIAL2136’ exhibits an adaxial foliar surface that is devoid of protuberances; and
  • 4. ‘AMIAL2136’ exhibits an abaxial foliar surface that is devoid of protuberances with the exception of the oldest foliage in the outer whorls of the rosette which occasionally exhibits a sparce to moderate abundance of small yellow-green protuberances that are loosely arranged in irregular longitudinal rows; and
  • 5. ‘AMIAL2136’ exhibits dentate leaf margins with an abundance of prominent spine-like teeth that are colored light greyed-green, generally appearing as a near-white color.

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 ‘AMIAL2136’ 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 ‘AMIAL2136’.

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 ‘AMIAL2136’.

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 ‘AMIAL2136’ 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 pest and disease control measures for mealybugs and botrytis. 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. ‘AMIAL2136’ 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.
