USPP30137P3 - Sansevieria plant named ‘SUPSAN1605’ - Google Patents

Abstract

A new and distinct Sansevieria plant named ‘SUPSAN1605’ which is characterized by the combination of a relatively large plant size, an upright to outward growth habit, long, linear succulent foliage with a semi-terete cross-section, green foliage with inconspicuous green radial bands, and the stability of all 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 Sansevieria hybrid.

Variety denomination: The inventive variety of Sansevieria disclosed herein has been given the variety denomination ‘SUPSAN1605’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2016/3021, filed Dec. 1, 2016, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Sansevieria variety ‘SUPSAN1605’ originated as a seedling selection from the controlled pollination of the proprietary seed parent, Sansevieria hybrid ‘MXJM1105’ (not patented), with the proprietary pollen parent, Sansevieria hybrid ‘MXJF1105’ (not patented). Both parents were developed by, and are owned by, the inventor and were never commercially released. Said crossing was conducted by the inventor in a small, netted greenhouse in Chonburi, Thailand in December of 2008. Seeds from said cross were harvested, then germinated, and the resulting seedlings were grown to a mature size in order to evaluate for a desirable combination of commercial characteristics. In June of 2011, one candidate plant was observed to exhibit a unique growth habit and leaf coloration. After confirmation of the distinctness and stability of the characteristics first observed, the inventor selected the new Sansevieria cultivar, ‘SUPSAN1605’, for commercial introduction.

Asexual Reproduction: Asexual reproduction of ‘SUPSAN1605’ by way of harvesting vegetative ground shoots was first initiated in June of 2011 at Chonburi, Thailand. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public. Through subsequent propagation of vegetative ground shoots, five generations have been reproduced which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SUPSAN1605’ has not been observed under all possible environmental conditions and 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 ‘SUPSAN1605’. These characteristics in combination distinguish ‘SUPSAN1605’ as a new and distinct Sansevieria cultivar:

• • 1. Sansevieria ‘SUPSAN1605’ is a relatively large plant with an upright to outward growth habit; and
  • 2. Sansevieria ‘SUPSAN1605’ exhibits a vertically flattened, orbicular plant form; and
  • 3. Sansevieria ‘SUPSAN1605’ exhibits long, linear succulent foliage with a semi-terete cross-section; and
  • 4. Sansevieria ‘SUPSAN1605’ exhibits green foliage with inconspicuous mottled radial bands which are slightly darker green.

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 ‘SUPSAN1605’ grown in a commercial greenhouse in Chonburi, Thailand. This plant is approximately 12 months old, shown planted in a 10 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 of ‘SUPSAN1605’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements, made in October of 2017, describe averages from a sample set of six specimens of 12 month old ‘SUPSAN1605’ plants grown in 10 cm containers, at a commercial greenhouse in Chonburi, Thailand. The plants were grown using conventional greenhouse production protocols for Sansevieria plants which consisted of overhead irrigation, 50% shade cloth, and no fertilizer. No photoperiodic or chemical treatments were given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SUPSAN1605’ 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).
