LATIN NAME OF THE GENUS AND SPECIES
Vanda hybrid.
VARIETY DENOMINATION
‘SPCDW1205’
BACKGROUND OF THE INVENTION
This application relates to a new cultivar of Vanda hybrid and claims priority to EU application 2012/1954 filed Sep. 17, 2012. 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 ‘M02’ with the unpatented, proprietary pollen parent referred to as Vanda ‘M58’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in January of 1989.
The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in September of 1993 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 ‘SPCDW1205’, assessing stability of the unique characteristics of this variety.
Asexual reproduction of the new cultivar ‘SPCDW1205’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in February of 2007. 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, 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 ‘SPCDW1205’ 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 ‘SPCDW1205.’ These characteristics in combination distinguish ‘SPCDW1205’ as a new and distinct Vanda cultivar:
1. Flowers with a white background, very heavily dotted greyed-purple.
2. Large flowers
3. Purple to greyed-purple lip color.
Parent Comparison
Plants of the new cultivar ‘SPCDW1205’ are similar to the seed parent, Vanda ‘M02’ in most horticultural characteristics. However the new variety, ‘SPCDW1205’ differs from ‘M02’ in the following characteristics:
- 1. Flowers of the new variety are have a patterned coloration, flowers of the parent variety are solid colored.
Plants of the new cultivar ‘SPCDW1205’ are similar to the pollen parent, Vanda ‘M58’ in most horticultural characteristics. However the new variety, ‘SPCDW1205’ differs from ‘M58’ in the following characteristics:
1. Larger flower size.
2. Different flower color.
Commerical Comparison
‘SPCDW1205’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘Black Magic’ in most horticultural characteristics. However the new variety, ‘SPCDW1205’ differs from ‘Black Magic’ in the following characteristics:
1. Flower color is red. Comparator flower color is dark purple.
2. Slightly darker leaf color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW1205’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. The plant is 5½ to 6½ years old. Plant is growing in a hanging basket without soil. FIG. 2 illustrates a close up of the flowers. The photographs were 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.
