P2005348: AHDB Knowledge Exchange Call - Providing raspberry growers with guidance on optimum storage of long-cane raspberries

Background

AHDB has been part-funding the UK raspberry breeding programme at the James Hutton Institute for more than 15 years and in that time, several promising new selections of summer fruiting raspberries have been named and released to the industry. Examples include Glen Doll, Glen Fyne, Glen Dee, Glen Ericht, Glen Carron, Glen Mor, Skye and Lewis.  They have been adopted by the industry to varying levels. Initially, growers have planted them in trial quantities to assess their performance on a small scale and compare them to standard industry cultivars such as Glen Ample and Tulameen.

The newly named cultivars are generally grown and managed in the systems that have been developed to suit the existing cultivars, but this does not necessarily suit the new ones. As a result, the new cultivars often fail to perform to their full potential and growers decide not to plant larger quantities, with the result that the new cultivar fails to have an impact that matches the significant funds and effort expended in the breeding and selection process.

The industry would therefore benefit if some additional funds were used to develop an optimum production system for new cultivars before their release to industry. This would help to form guidelines for plant raisers and growers on how best to produce and grow the new cultivars so that they achieve their full potential whenever they are planted in small quantities. Growers could then make a fairer comparison with the standard cultivars and avoid new selections from being discarded too soon following their release.

Purpose/primary objective

There are a number of parameters within the production of raspberry cultivars which could be assessed and developed including their optimum growing density in propagation, optimum support systems, nutritional needs and improved understanding of their pest and disease susceptibility. However, with funds limited, AHDB would prefer to focus on an area that can have a major impact on the yield and fruit quality such as optimum chilling requirement and cold storage.

A very high proportion of summer fruiting raspberry cultivars are now produced as ‘long canes’ which are ready for planting out and cropping in the year of establishment (some 90 days later). Plant raisers and growers would find it useful to know the optimum chilling requirement and duration of cold-storage required for each cultivar to achieve maximum bud break and full yield potential with optimum fruit size and quality.

Scope

We are therefore inviting research or advisory organisations to tender for funding to identify optimum chilling and duration of cold storage for the most promising selections likely to be released to the industry from the UK raspberry breeding programme and any other relevant programmes that UK growers are making use of. This would involve procuring container-grown ‘long-canes’ from the propagation phase at staggered dates in the autumn and early winter, storing the canes at different temperatures and for different durations, then planting them out at staggered times in the spring and early summer and recording their bud-break, total yield and fruit quality.

For each selection/cultivar assessed, the results would provide information to form guidance to propagators and growers of the optimum time to put the canes into cold store, the optimum temperature to hold them at and the optimum duration of storage to maximise yield and fruit quality in the year of planting.

Initially, the funding would be for one year of work which would begin in autumn 2020 and run through the storage season to spring and early summer 2021.

Collaboration with other organisations with knowledge and skills in propagating long-cane material and its storage would be welcomed.

Specific objectives

  • Identify new raspberry selections or named cultivars from the UK raspberry breeding programme or other programmes being used by UK growers which need to be assessed for their cold storage requirement.

  • Procure the chosen selections/named cultivars as container-grown ‘long-cane’ material in the autumn months.

  • Produce an experimental protocol which should be set up to determine the optimum cold storage temperature and optimum duration of storage for each selection/cultivar chosen.

  • Assess and compare the relative yields and fruit quality produced from each selection/cultivar at the chosen range of cold storage conditions.

  • Provide the results presented in ‘web-friendly’ text which will form guidance to growers which can be read on the AHDB website.

  • Present the results at AHDB and other industry fruit events.
