Anthurium (Anthurium andraeanum Hort.), a tropical herbaceous perennial, is one of the most important cut-flower crops in the global floriculture industry. It produces a showy, brightly colored, and modified bract (spathe), and a stalk-like inflorescence (spadix), which are carried on a long, slender peduncle. Cut anthuriums are also known for their especially long vase life, depending on the variety, season, and cultivation conditions (Elibox and Umaharan, 2010; Farrell et al., 2012; Paull et al., 1992).
Anthuriums grow best when the maximum daytime temperatures range from 26 to 32 °C in advanced greenhouses equipped with temperature and humidity controls. However, in many tropical areas located far from their original habitat, they are also grown in simplified, shaded greenhouses to reduce production costs, and therefore often suffer heat stress (>32 °C) in summer and cold stress (<16 °C) in winter, which reduces productivity, and impacts spathe coloration and other quality traits negatively. Although some commercial cultivars have been released and are grown extensively, many more with novel colors and shapes, high-stress tolerance, long-lasting vase life, and so on, are still urgently needed in the anthurium industry.
In the early 2000s, the Tropical Crops Genetic Resources Institute, Chinese Academy of Tropical Agricultural Sciences (TCGRI-CATAS) launched breeding programs to develop new cut anthurium cultivars adapted to the South China climate. ‘Victory Flag’, presented here, is a promising hybrid that meets current market and regional industry standards.
