Soft fruit and perennial crop genetics
Soft fruit genetics research at The James Hutton Institute is focused on a number of key genera:
- Rubus (raspberries, blackberries and hybrid berries such as `Tayberry’)
- Ribes (currants and gooseberries)
- Vaccinium (blueberries)
- Lonicera (honeyberry)
- Prunus (cherry)
Research within the fruit group aims to support the soft fruit sector including growers, breeders and ultimately consumers to meet the many current and future challenges in production and quality. The main areas of interest include:
- Linking genotype to phenotype, through the development of genetic linkage maps and association mapping of robust trait data.
- Marker development and downstream deployment strategies into breeding programmes.
- Physical mapping (Rubus) and gene discovery/transcriptomics related to key traits for breeding.
- Fruit quality, especially health-related components and sensory traits, particularly their heritability and genetic control.
- Investigations of factors linked to environmentally sustainable production, for example, pest and disease resistance, climate adaptation, low input and resilience in germplasm.
- Utilisation of the extensive genetic resources at the Institute to develop new germplasm aligned with emerging problems and opportunities.
- Improved and high throughput phenotyping including the use of plant imaging technologies.
Listen now to our Hutton Highlights podcast where we speak with experts and growers about what could be Scotland’s fifth soft fruit – the honeyberry. We hear how it’s not only a superfood, but one that’s also well suited to Scotland’s climate. It could help farms diversify as well as bring benefits to their land, from an environmental perspective.
The results of the research within soft fruit genetics are applied within commercially-funded breeding programmes, for the production of improved cultivars for the UK fruit industry.
The commercial breeding programmes carried out through James Hutton Limited have until recently been based on classical hybridisation and recently the application of marrker-assisted breeding has been used to reduce the time to cultivar production with the key traits of interest. a good example is the cultivar Glen Mor with resistance to raspberry root rot using marker assisted breeding. Outputs are often linked to specific processes, products and markets and several Institute cultivars of blackcurrant, raspberry and blackberry are leaders in their respective sectors. New blueberry cultivars adapted to UK conditions are currently in development. The soft fruit group work extensively with stakeholders to carry out specific research proposals often through Innovate UK to address specific and targetted needs of the sector.
