USPP26562P3 - Sansevieria plant named ‘SUPSAN1301’ - Google Patents

Abstract

A new and distinct Sansevieria cultivar named ‘SUPSAN1301’ is disclosed, characterized by unique plant form, rosette leaf arrangement, and leaves that change from cylindrical to less terete as they mature. The new variety is a Sansevieria, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Sansevieria aeethiopica×cylindrica.

Variety denomination: ‘SUPSAN1301’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Sansevieria aeethiopica×cylindrica. The new variety is the product of a planned breeding program, originating as a seedling from the open pollination of an unpatented, unnamed, proprietary seed parent Sansevieria aeethiopica with an unknown, unpatented, proprietary pollen parent variety of Sanservieria cylindrica. The actual pollen variety is unknown because the cross was made by means of open pollination process in a nursery where several proprietary hybrids of Sanservieria cylindrica were present. Any of the present hybrids could have acted as the pollen variety. All aforementioned Sanservieria cylindrica hybrids were created by the breeder and never commercially introduced or published and therefore do not have a variety name. The open pollination took place in 2003.

The new variety was first observed by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in 2005 after planting as a seedling in 2004 in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SUPSAN1301’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SUPSAN1301’ was first performed at a research greenhouse belonging to the inventor in Chonburi, Thailand by leaf cuttings of original plant in 2005. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, belonging to the inventor, and not accessible to the public. Through subsequent propagation, more than 8 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 ‘SUPSAN1301’ 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 ‘SUPSAN1301’. These characteristics in combination distinguish ‘SUPSAN1301’ as a new and distinct Sansevieria cultivar:

• • 1. The young leaves of the candidate variety have a more cylindrical shape and as they mature, the form gradually changes from cylindrical to less and less terete.
  • 2. Shape of plant; leaves arranged more as a rosette, rather than arranged in as a fan shape, or spiral which is common for Sanservieria cylindrica varieties.
  • 3. Growth habit of the plant is unique as a whole.

PARENT COMPARISON

Plants of the new cultivar ‘SUPSAN1301’ are similar to the seed parent, the unpatented, unnamed, proprietary Sansevieria aeethiopica in most horticultural characteristics. However the new variety, ‘SUPSAN1301’ differs from seed parent in the following characteristics:

• • 1. Leaves much longer and pointy, thicker in caliber and much more terete to cylindrical. Mother variety; leaves much flatter, shorter and broader.
  • 2. More heavily branched, leaves arranged in a more rosette like way.
  • 3. Taller less compact form.

Plants of the new cultivar ‘SUPSAN1301’ are similar to the possible but unknown pollen parent, Sanservieria cylindrica in most horticultural characteristics. However the new variety, ‘SUPSAN1301’ differs from possible pollen parent in the following characteristics:

• • 1. Shorter leaves, less cylindrical than father variety. Leaves mature from more cylindrical to more terete.
  • 2. Rosette growth form. Farther variety is of fan shape to spiraling form.
  • 3. Leaf texture is smoother.

COMMERCIAL COMPARISON

There is no similar variety but ‘SUPSAN1301’ could perhaps be best compared with the unpatented commercial variety Sanservieria cylindrica ‘Skyline’ because the spotting of the leaf is somewhat similar. However the new variety, ‘SUPSAN1301’ differs from ‘Skyline’ in the following characteristics:

• • 1. Leaves have slight arch. Comparator has straight leaves.
  • 2. Branches very heavily. Branches produce many leaves with very short internodes. Comparator produces long branches which have leaves with very long internodes.
  • 3. More rosette form. Comparator form is more fan shaped.
  • 4. Very smooth leaf texture. Comparator leaf texture is coarse.
  • 5. Leaves are less cylindrical to terete. Comparator leafs are more cylindrical.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SUPSAN1301’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. The plant is 40 weeks old a 12 cm circular pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
