New hybrids of torch ginger as a cut flower in Thailand
Five torch ginger hybrids (Etlingera elatior × Etlingera fulgens) were planted at three locations (the Chiang Rai, Loei and Chanthaburi Horticultural Research Centers) during 2016-2019 to evaluate yield and flower quality in comparison with a commercial cultivar 'Dang Dok'. The four hybrids had export-suitable cup-shaped flowers, with dark red, red or red-pink bracts. The flowers were approximately half the size of 'Dang Dok', but with comparable peduncle length. Yields of these hybrid clones ranged from 129 to 404 flowers clump‑1 year‑1, but varied by location depending on soil pH and the amount of exchangeable potassium. Clone #8 performed very well in all testing locations, yielding 244-361 flowers clump‑1 year‑1, and was named 'Yala 1'. Vase life of the four hybrids, harvested at 50% flower opening stage, were 8.0-9.9 days at ambient conditions, similar to that of 'Dang Dok'.
