plant named ‘SPCDW1103’

Abstract

A new and distinct Vanda cultivar named ‘SPCDW1103’ is disclosed, characterized by petals and sepals colored white with light purple netting. 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: ‘SPCDW1103’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda, as described in EU application number 2011/2164, filed Sep. 12, 2011, 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 ‘G248815’ with the unpatented, proprietary pollen parent referred to as Vanda ‘CTRV1815’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in October of 1987.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in June 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 ‘SPCDW1103’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SPCDW1103’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in March of 1998. 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 ‘SPCDW1103’ 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 ‘SPCDW1103’. These characteristics in combination distinguish ‘SPCDW1103’ as a new and distinct Vanda cultivar:

• • 1. Unique sepal and petal coloration of white with light purple netting.
  • 2. Improved plant compatibility for commercial growing methods.

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW1103’ are similar to the seed parent, Vanda ‘G248815’ in most horticultural characteristics. The new variety, however, produces flowers with a different color than the seed parent.

Plants of the new cultivar ‘SPCDW1103’ are similar to the pollen parent, Vanda ‘CTRV1815’ in most horticultural characteristics. The new variety, however, produces flowers more easily than the pollen parent.

COMMERCIAL COMPARISON

‘SPCDW1103’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘Blue Magic’ in most horticultural characteristics. The new variety, however, produces sepals and petals colored white with light purple netting, whereas ‘Blue Magic’ produces petals and sepals that are white with a thick, dark purple netting. Additionally, the new variety has a lip colored medium purple, whereas ‘Blue Magic’ has a lip color of dark purple.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW1103’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 5.5 years old, shown planted in a 8 cm container. 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 2001, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SPCDW1103’ plants grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures ranged were approximately 23° C. during the day and 19° C. 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. Measurements and numerical values represent averages of typical plant types.
