Abstract

A new and distinct Gasteria cultivar named ‘AMIAL1622’ which is characterized by thick succulent foliage arranged in a compact rosette with an erect to arched attitude, near ovate to deltoid foliage that is dark green and moderately to densely covered with near white papillae, as well as 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 Gasteria hybrid.

Variety denomination: The inventive variety of Gasteria disclosed herein has been given the variety denomination ‘AMIAL1622’.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIAL1622’ is the result of a planned breeding program carried out at a commercial greenhouse in Heerhugowaard, The Netherlands. In the spring of 2013, the inventor performed the controlled intergeneric cross-pollination of the species Gasteria carinata (an unnamed plant), the seed parent, with the species Aloe aristata (an unnamed plant), the pollen parent. In early 2014, a seedling that exhibited potential commercial value was selected from all other progeny of the same cross. The seedling was given the reference code “16-0098” and allowed to grow to a mature size, for further evaluation to confirm the stability of the characteristics initially observed. In the summer of 2014, the claimed plant was selected for commercialized.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL1622’, by way of rooting leaf cuttings, was first initiated in the summer of 2015 at the inventor's commercial greenhouse in Heerhugowaard, The Netherlands. Through three subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIAL1622’ 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 ‘AMIAL1622’. These characteristics in combination distinguish ‘AMIAL1622’ as a new and distinct Gasteria cultivar:

    • 1. ‘AMIAL1622’ exhibits thick succulent foliage with an erect to arched attitude, arranged in a compact rosette; and
    • 2. ‘AMIAL1622’ exhibits large leaves that are near ovate to deltoid in shape, with an apiculate apex; and
    • 3. ‘AMIAL1622’ exhibits dark green leaves which are moderately covered with white papillae on the adaxial leaf surface and densely covered with near white papillae on the abaxial leaf surface.
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 ‘AMIAL1622’ grown in a commercial greenhouse in Heerhugowaard, The Netherlands. This plant is approximately 9 months old, shown planted in a 10.5 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage arrangement of ‘AMIAL1622’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage ‘AMIAL1622’.

FIG. 4 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 ‘AMIAL1622’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in January of 2017 describe averages from a sample set of six specimens of 9 months old ‘AMIAL1622’ plants grown in 10 cm nursery containers at commercial greenhouse in Heerhugowaard, The Netherlands. Plants were produced using conventional greenhouse production protocols for Gasteria which consisted of minimal irrigation and fertilizer applications, and chemical pest and disease control measures against mealy bug and Botrytis as required. Plants were grown under approximately 50 percent shade and 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. ‘AMIAL1622’ 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, 2015 (sixth edition).
