Virus-free passionfruit seedlings were examined by molecular detection methodtransferred to Vietnam. Currently, Vietnam can produce 4 million seedlings a year, becoming an important passionfruit production country. In 2018, ‘Nafoods-NCHU Plant Virus Certification Center’ was established to ensure the production of virus-free passionfruit seedlings. Currently, we are developing mild vaccine to protect passionfruit for sustainable production.

The established of office ‘Nafoods-NCHU Plant Virus Certification Center’  provides several passionfruit viruses detection methods in order to assist the Vietnam companies to produce certified virus-free passionfruit seedlings. The cross-protection strategy will protect the plants against the severe virus infection which is an alternatives strategy in replacement of transgenic resistant strategy.

The virus-free certification technology has been transferred to Nafoods company, in Vietnam by a ten-year agreement with the technology transfer fee 2.4 million Taiwan dollars to NCHU. This technology transfer will serve as a good example for the future collaboration between TaiwanVietnam, also to other Asean countries. Our cross protection assay indicates that the mild virus vaccine have gre
