摘　　要：Orchids make up one of the largest families of flowering plants(Orchidaceae) with a variety of ecological habitats and broad economic impact for their ornamental and medicinal values in the world.Sexual hybridization followed by the selection of attractive traits in progenies is a classical but dominant method for breeding new and improved orchid varieties. This method is typically time-consuming as most orchid genera possess a long vegetative phase that could last from one year to many years(Yu and Goh, 2001). Thus, the protracted breeding period so far remains a bottleneck for the rapid production of new orchid varieties to satisfy consumer appetites for desirable traits.
