orchid plant ‘SPCDW1203’

Abstract

A new and distinct Vanda cultivar named ‘SPCDW1203’ is disclosed, characterized by unique petal coloration of greyed-orange with greyed-red spots and stripes. The plant shows a strong tolerance of cold temperatures, for the Genus. The new variety is a Vanda, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Vanda hybrid.

Variety denomination: ‘SPCDW1203’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda, as described in EU application number 2012/1586, filed Jul. 17, 2012, grant pending, to which applicant claims priority. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘TKJL’ with the unpatented, proprietary pollen parent referred to as Vanda ‘D2JK’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in June of 2001.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in May of 2006, 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 ‘SPCDW1203’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SPCDW1203’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture, using tissue from the base of the foliage, in June of 2006. 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. Vanda propagation can be done by taking a cutting of a tip off a plant. A plant will have aerial roots, and some of these aerial roots emerge from a branch of the orchid plant between sets of leaves. Cut off the tip of the plant just below where these roots emerge, and you will have a cutting that already has aerial roots.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1203’ 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 ‘SPCDW1203’. These characteristics in combination distinguish ‘SPCDW1203’ as a new and distinct Vanda cultivar:

• • 1. Unusual greyed-orange petal color with greyed-red spots and stripes.
  • 2. Durable foliage.
  • 3. Good tolerance for cold temperatures, for the Genus
  • 4. Ligulate, foliage which is strongly carinate and slightly curved in aspect.

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW1203’ are similar to the seed parent, Vanda in most horticultural characteristics. The new variety, however, produces larger flowers than the seed parent.

Plants of the new cultivar ‘SPCDW1203’ are similar to the pollen parent, Vanda in most horticultural characteristics. Plants of the new variety, however, are more compact than the pollen parent.

COMMERCIAL COMPARISON

‘SPCDW1203’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘Sunanda Magic Gold’ in most horticultural characteristics. The new variety, however, produces sepals and petals colored orange with brown spots, whereas ‘Sunanda Magic Gold’ produces petals and sepals that are yellow with brown spots. The brown spots found on petals and sepals of ‘SPCDW1203’ are larger than those found on ‘Sunanda Magic Gold’. The new variety has a flower with a different lip shape, and different dorsal sepals than ‘Sunanda Magic Gold’. Additionally, the flower size of the new variety is smaller than that of ‘Sunanda Magic Gold’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW1203’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 3 years old.

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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
