Variety traits

Phalaenopsis flower color

Phalaenopsis Bl.

A diagnostic trait in DUS testing of Phalaenopsis, assessed according to international UPOV protocols using the RHS chart and the CIELab system.

In the reference 95 varieties crop Moth Orchid, where this is mentioned in the description.

The evaluation of Phalaenopsis color is performed on fully open flowers when at least 50% of the inflorescence has bloomed. The examination covers the inner side of the petals, sepals, lip, and column. The Royal Horticultural Society (RHS) color chart serves as the primary tool for shade recording, while the CIELab coordinate system is used for the quantitative analysis of anthocyanin pigment accumulation.

In breeding, color is defined as a combination of the primary and secondary colors, such as spots or stripes. Genetic studies focus on managing the expression of the PeMYB2, PeF3H, and PeDFR genes to obtain new patterns. During the examination for distinctness, uniformity, and stability (DUS) of varieties, a key requirement is the preservation of species-specific color characteristics, which allows for the differentiation of natural traits from artificial coloring.
