The debate around low chill versus high chill blueberries continues to surface in industry discussions. In reality, this is not a competition — it is a portfolio.

Low and zero chill genetics have transformed global production over the past decade. They have opened new regions, extended supply windows and, importantly, raised the bar in fruit quality. In many cases, modern low chill cultivars now compete directly — and sometimes favourably — against traditional high chill fruit in terms of firmness, consistency and eating experience.

This shift has changed expectations.

High chill production remains fundamental to global supply, particularly in key regions such as Poland, Chile and China. During recent visits to these markets, it has been clear that growers recognise the need for continued genetic improvement. Yield alone is no longer sufficient; fruit quality and commercial performance must match modern retailer and consumer standards.

At GPG, our work reflects this balanced perspective. Our collaboration with Oregon Blueberry spans both high chill advancement and low chill development, with the forthcoming release of Astoria (OBG-18064) signalling progress in high chill quality improvement. Alongside this, our relationship with the University of Georgia continues to strengthen zero and low chill innovation.

The future of blueberries will not be defined by one chill category over another. It will be shaped by strategic diversification, improved genetics and a clear understanding that resilience comes from balance.
