Interest in blueberry cultivation continues to expand globally, with demand, production, and supply rising. Conversations with consumers highlight health benefits and flavor, while growers focus on improved cultivation and extended seasons. Plant breeding significantly influences these developments, enhancing the blueberry experience across the supply chain.
Globally, over 260,000 hectares of blueberry plantations are active, with a 30% increase since 2019. These plantations are almost equally divided between warmer and cooler climates. Low-chill Southern Highbush types thrive in warm areas, while high-chill Northern Highbush cultivars suit cooler regions. Some regions also utilize Rabbiteye and mid-chill cultivars.
In the past decade, breeding has focused on Southern Highbush blueberries for warm regions, boosting fruit quality and yields. However, advancements in Northern Highbush genetics are less apparent. Low-chill genetics yield more per hectare, widening the gap with high-chill varieties.
The Northern Highbush sector faces opportunities and challenges. Consumers, retailers, and marketers expect consistent quality year-round, akin to leading low-chill varieties. Growers need new Northern Highbush varieties offering improved quality and higher yields to compete effectively.
GPG collaborates with Oregon Blueberry in the USA, focusing on breeding new varieties for all climates, including high-chill regions. Upcoming releases promise to impact the Northern Highbush sector. More information will follow.
