New TTDARES-bred Dendrobium Nobile Varieties Registered with Royal Horticulture Society: Taitung Wedding, Taitung Quartz Pink, and Taitung Positive Passion

2021-06-23

After six years of work on breeding new varieties of Dendrobium nobile by the Taitung District Agricultural Research and Extension Station (TTDARES) of the Council of Agriculture, Executive Yuan, three such varieties (Taitung wedding, Taitung quartz pink, and Taitung positive passion) were registered with the Royal Horticulture Society on January 4, 2020. The three are yellow-flowered hybrids whose plump flowers bloom readily even in warm environments while maintaining their leaves, which makes them great for commercial mass production. They are grown at low altitudes (below 50 meters) in greenhouses or net houses. Since they do not need to be kept cool, their carbon footprint, an aspect the international community is highly concerned with, is much smaller and production costs are lower.

Taitung wedding has multiple stems, producing three annually. The eye-catching flowers are large, bright in color with strong contrast, and grow as tall as 30 centimeters. Taitung quartz pink changes in color: the blooms first appear as light yellow before gradually becoming pink, a relatively rare phenomenon on the commercial market. Taitung positive passion has deep yellow, mid-sized blooms whose petal edges are embellished with a red-purple, and it readily blooms in warm temperatures. Dendrobium nobile is a crucial element in driving Taitung’s competitiveness in the industry. In recent years, major flower companies from the US and Europe have actively sought out new varieties in Taiwan, so breeding good new strains has become important in boosting competitiveness. The three varieties introduced here will be promoted through means of paid transfers or variety rights permission, accelerating the diversification of usage and contributing to a strong foundation for Taiwan’s Dendrobium nobile industry.
