On September 2, 2026, Hainan University’s Sanya South Breeding Research Institute successfully mastered the core technology for tissue culture propagation of glutinous coconut. This variety is a naturally occurring variant with an extremely low probability of occurrence (mutation rate of only 0.15%), and it has long faced challenges such as severe browning and low embryo induction rates. The research team developed specialized tissue culture and embryo cultivation techniques, achieving asexual propagation through somatic embryogenesis, while retaining 100% of the parental plant’s genetic information to maintain glutinous properties. Additionally, the team used multi-dimensional omics technology to identify key gene loci and established a progressive verification system suitable for a fruit-bearing cycle of 4 to 5 years, ensuring full-cycle control over survival rates, stress resistance, and yield quality. The first batch of high-quality glutinous coconut seedlings independently cultivated has been planted at the Sanya Yazhou Bay South Breeding Base and is growing steadily. Subsequent evaluation will be conducted from aspects such as trait stability and economic benefits to initiate large-scale demonstration and promotion after meeting standards.
On September 2, Hainan University’s Sanya South Breeding Institute successfully mastered the core technology for tissue culture propagation of glutinous rice coconut. The first batch of high-quality glutinous rice coconut seedlings cultivated independently has been planted at the Sanya Yazhou Bay South Breeding Base. This variety is a naturally occurring variant with an extremely low probability of occurrence, with a mutation rate of only 0.15%. It also cannot germinate naturally, facing challenges such as severe browning and low embryo induction rates over time. The research team developed exclusive tissue culture and embryo cultivation techniques, using somatic embryogenesis to propagate without sexual reproduction, ensuring 100% retention of the mother plant’s genetic information to maintain glutinous quality. Additionally, the team utilized multi-dimensional genomics technology to identify key gene loci and established a progressive verification system suitable for a fruit-bearing cycle of 4 to 5 years, comprehensively controlling survival rates, growth resistance, and yield quality throughout the entire process. Currently, the seedlings are growing steadily, and subsequent large-scale demonstration and promotion will be initiated after comprehensive evaluation of traits stability and economic benefits.
