Abstract:
There is a need to improve the existing germplasm of yellow pitaya (Selenicereus megalanthus),
particularly for fruit quality and traits. The genetic transformation requires organogenesis and shoot
regeneration protocols. Therefore, the in vitro culture of the plant was successfully established from
mature seeds. Results showed that 90% of the seeds were germinated. The plantlets require MS
basalt medium for growth. MS added with 2 mg/L BAP (6-benzyldadenine) was suitable for
organogenesis and production of explant for other purposes
