摘要： The disclosure provides an aseptic sowing and raising seedling method for distant hybridization seeds of Phalaenopsis and Rhynchostylis retusa, which takes Phalaenopsis as female parent and Rhynchostylis retusa as male parent to obtain hybridization fruit pods by artificial pollination, the fruit pods are pretreated, and the seeds are aseptically sowed, germinated, protocorm proliferated and differentiated, strong seedlings rooted, acclimatized and transplanted to obtain distant hybridization offspring groups. The disclosure has the advantages of high seed germination rate, large seedling number, short seedling time and good seedling quality, which solves the problems that the seeds of Phalaenopsis distant hybridization process are difficult to succeed due to affinity, and are extremely difficult to germinate and raise seedlings under natural conditions. Therefore, a large number of seedlings can be obtained in a short period by aseptic sowing and artificial propagation, which lays a foundation for breeding excellent varieties of Phalaenopsis distant hybridization.
