Modelling the dormancy and chilling requirements in raspberry

The Raspberry Breeding Consortium (RBC) at James Hutton Limited is breeding a number of new floricane and primocane raspberry varieties. To help the industry successfully use these new varieties, a report has established their dormancy and chilling needs.

Why is this report relevant?

The global trend in raspberry production is for cold-stored, long cane material produced in pots of substrate.

This approach minimises costs and pest and disease problems. However, this technique relies on a good understanding of the dormancy and chilling requirements of each variety.

How will the report help me?

The information in the report will help you to:

  • Match varieties to specific commercial needs, such as long cane production and use in cold or warm climates
  • Optimise cold storage for long cane production by variety
  • Manipulate crop timings to programme production
  • Maximise yields by ensuring complete bud break
  • Understand the resilience of varieties in different climatic conditions
  • Harvest long cane plants at the optimum time to ensure successful cold storage and bud break
