Good start
After 10 years of research, the creation of this dragon fruit has been successful since 2010, but the LD5 purple-fleshed dragon fruit variety has only been officially launched by SOFRI to the market after selling the copyright. Previously, the red flesh dragon fruit was also successfully researched by SOFRI in 2005 but could not sell the copyright. "At that time, the use of" pagoda "became too popular", said Assoc.
Now SOFRI has taken a more formal step. According to Assoc. Prof. Dr. Nguyen Minh Chau, copyright issues for plant varieties have been applied in many developed countries. When creating a new variety, the researcher will sell the right to exploit the seed to a company for them to organize the exploitation. The company will have full rights to exploit in their direction and is also the only unit authorized to organize production, sale of seedlings or export of fruit later.
The Intellectual Property Law relating to plant variety copyrights clearly stipulates that no individual or organization is allowed to plant or trade such variety without an agreement with the company that buys the copyright. The fact that a company buys the rights to exploit seed in developed countries is a great motivation for the research institutes to continue to produce better new varieties.
According to SOFRI, Vietnam joined UPOV (International Plant Variety Copyright Organization) in December 2006. Protection of plant varieties will be a guarantee for farmers to invest in producing the best plant varieties, facilitating re-investment in seed development research. However, up to now, the licensing of plant varieties has only been popular and developed in most of the northern provinces. As for the southern region, there has not been any direct exchange on this issue with cooperatives and gardeners.
