MGI Tech and Lincoln University: Innovating New Zealand's Viticulture with Genomics

In a groundbreaking collaboration, MGI Tech Co., Ltd. has partnered with Lincoln University in New Zealand to tackle sustainability challenges in the viticulture sector. This initiative focuses on employing advanced genomic sequencing technology to breed grapevine and hop varieties that are resilient against pests and diseases, aiming to significantly reduce the reliance on chemical sprays within New Zealand's $2.1 billion wine industry.

The Challenges Facing New Zealand's Viticulture

As the sixth largest source of export revenue for New Zealand, viticulture is crucial to the economy. However, the industry is under increasing pressure to enhance its sustainability practices and minimize environmental impacts. Vineyards are susceptible to a range of fungal diseases that often necessitate extensive pesticide use; New Zealand relies on approximately 3,400 tonnes of pesticides annually. Alarmingly, considerable proportions of these, including 60% of fungicides, are classified as potential carcinogens by the U.S. Environmental Protection Agency, prompting scrutiny from consumers and environmental advocates alike.

The challenges are exacerbated by climate change, leading to unpredictable weather patterns that increase the likelihood of disease and pests affecting grape and hop health. To address these issues, researchers are implementing genomic technologies that promise to revolutionize disease management in New Zealand vineyards.

Leveraging Genomics for Sustainable Solutions

A team of researchers from Lincoln University has embarked on a mission to reduce chemical dependence in the wine sector through genomic advancements. Utilizing cutting-edge sequencing technology, they can rapidly analyze thousands of grapevine samples to pinpoint those exhibiting natural resistance to diseases.

Associate Professor Christopher Winefield, a leader in the Department of Wine, Food and Molecular Biosciences, is at the forefront of integrating genomics into viticulture studies. Initial findings indicate that genomic data could facilitate a significant reduction of up to 80% in the use of chemical sprays in certain vineyards, a change that could transform the landscape of grapevine management.
