Researchers at Lincoln University are applying advanced DNA sequencing to grapevines to identify natural resistance traits. The study is positioned to reduce chemical spray use and support the $2.1 billion wine export industry. Up to 80% less fungicide may be needed if successful.
Genome Sequencing Deployment in Commercial Viticulture
The genome research is being carried out at Lincoln University’s Department of Wine, Food & Molecular Biosciences. Led by Associate Professor Christopher Winefield and Dr. Bicheng Yang, the project is the first in New Zealand to apply the MGI DNBSEQ-G400 to viticulture.
“The wine industry is a major contributor to the New Zealand economy, but it’s also facing huge challenges around sustainability,” said Winefield.
“Vineyards are heavily reliant on chemicals to fight fungal disease and that can come at a cost to the soil microbiome, long-term crop health and the environment.”
Laboratory Capacity Upgrade Enables Scalable Testing
The MGI DNBSEQ-G400 sequencer installed at Lincoln University allows researchers to process over 50,000 grapevine samples each year.
“In the past, we have been limited to being able to sample a few hundred vines a year, but with the new system installed, the lab can now process more than 50,000 a year,” said Associate Professor Christopher Winefield.
“Having this technology on site means we no longer have to send samples offshore for analysis. That’s saving time and money and allowing us to move at a completely different scale.”
Commercial Venture to Broaden Industry Access
The research group is developing a commercial platform to make genomic testing accessible across the primary sector. “This is about taking world-class science out of the lab and into the field – and transforming how primary industries manage disease and productivity at the grassroots level,” said Winefield.
Climate-Driven Risk Management Through Genomics
Researchers say climate change is altering the timing and distribution of crop diseases. “We’re seeing diseases appear earlier in the season, or in regions where they weren’t previously a problem,” said Associate Professor Christopher Winefield. “Genomic monitoring gives us the tools to respond to these changes with precision.”
“This is a powerful example of how cutting-edge genomics can support the long-term sustainability of key industries.” Dr. Bicheng Yang noted.
“New Zealand may never feed the world by volume, but we can absolutely feed it through better science, by exporting the genetic tools and insights that lift productivity and resilience globally.” Winefield stated.
