plant named ‘SPCDW1403’

Abstract

A new and distinct Vanda cultivar named ‘SPCDW1403’ which is characterized by the combination of a light cream-yellow flower with light brown spotting of both the sepals and petals, an undulating sepal and petal margins, and the stability of all characteristics from generation to generation. The new variety is a Vanda, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Vanda spp. Jones ex R. Br.

Variety denomination: The inventive variety of Vanda disclosed herein has been given the variety denomination ‘SPCDW1403’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2014/2632, filed Oct. 27, 2014, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Vanda variety ‘SPCDW1403’ is the result of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘A169’ with the unpatented, proprietary pollen parent referred to as Vanda ‘JBP’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in October of 2002.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in April of 2007, 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 ‘SPCDW1403’, assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘SPCDW1403’ was first initiated at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in April of 2008, with the first mericlones so reproduced flowering in 2013. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation by vegetative cuttings, multiple 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 ‘SPCDW1403’ 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 ‘SPCDW1403’. These characteristics in combination distinguish ‘SPCDW1403’ as a new and distinct Vanda cultivar:

• • 1. Vanda ‘SPCDW1403’ exhibits a light cream-yellow flower; and,
  • 2. Vanda ‘SPCDW1403’ exhibits a unique light brown spotting pattern of the sepals and petals; and,
  • 3. Vanda ‘SPCDW1403’ exhibits strong undulation of both the sepal and petal margins.

This plant is approximately 5 years old, shown planted in an 8 by 8 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 ‘SPCDW1403’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical flowers of ‘SPCDW1403’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements describe a five year-old ‘SPCDW1403’ plant grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures ranged were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. When natural lighting fell below 150 Watt, artificial lighting is given at 10,000 lux for 16 hours a day.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1403’ 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, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2007 (fifth edition).
