Key Takeaways:
- The James Hutton Institute launches an enhanced breeding programme to develop climate-resilient blackcurrant varieties.
- Focus areas include yield consistency, pest and disease resistance, and retention of flavour and nutritional value.
- New tools will enable earlier and more accurate yield forecasts for growers.
- Collaboration with SBF GB&I aims to secure the future supply for Ribena production.
- Molecular marker technology will help identify resistant plants earlier in the breeding process.
James Hutton Institute Advances Blackcurrant Breeding for Resilience
The James Hutton Institute has announced a major investment to accelerate the development of blackcurrant varieties capable of delivering consistent yields under climate change pressures. The breeding programme, in partnership with SBF GB&I, is designed to ensure blackcurrants remain viable for UK growers despite weather extremes, pests, and diseases.
Dr Amanda Moura, Soft Fruit Breeder at the James Hutton Institute, said the work would provide greater security for the industry. “We are strongly committed to the development of a new generation of blackcurrant varieties that can continue thriving in the UK while adapting to the challenges posed by climate change and pests’ pressures,” she noted.
Focus on Yield Stability and Climate Adaptation
The breeding programme targets blackcurrants that can maintain yield consistency despite environmental stress, including limited winter chilling, heat, and drought. New field-based and laboratory tools will also be introduced to deliver earlier and more accurate yield forecasts, enabling growers to make informed decisions in unpredictable seasons.
According to Harriet Prosser, Agronomist at SBF GB&I, this work is critical to protecting both the crop and the growers. “This season’s weather extremes have shown that investment in fruit varietal breeding is vital to protect the future of both the blackcurrant crop and the growers who depend on it,” she said.
Pest and Disease Resistance With James Hutton Institute's Molecular Marker Technology
As plant protection products are increasingly withdrawn in the UK, the programme will prioritise natural resistance to major pests and diseases. Molecular marker technology developed at the James Hutton Institute allows early identification of resistant plants, which are now being trialled to support more sustainable production.
This approach aims to reduce reliance on chemical controls while safeguarding yields.
Flavour and Nutrition Remain Central Goals For James Hutton Institute
Every potential variety will be assessed for flavour and nutritional content to preserve the distinctive taste associated with Ribena, while seeking to enhance health benefits. The breeding work will maintain high natural levels of vitamin C and anthocyanins, alongside efforts to improve sweetness.
The James Hutton Institute sees this as a long-term investment in the sustainability, resilience, and quality of the UK’s blackcurrant industry.
