The progress of raspberry breeding in Scotland

S.N. Jennings, L. Ferguson
James Hutton Ltd has introduced three new raspberry cultivars; ‘Skye’ and ‘Lewis’, the first two primocane cultivars from the programme and floricane ‘Glen Mor’, the first cultivar with the molecular marker for root rot resistance. These cultivars will offer growers productive, high quality fruit with reduced labour costs, especially picking costs, in the form of large fruit which are easy to deplug and well presented to the pickers. The development of markers to identify important traits enables the breeder to quickly identify the best parents to use and screen resulting progeny. In addition to the routine deployment of the root rot markers, other markers are in the pipeline for fruit size, yield and crumbly fruit. Dormancy assessments are made to determine relative chill requirement of advanced material. This ensures bud break and reliable production after warmer winters and optimises cold storage of long cane. Breeding robust, resilient cultivars are key to making fruit production systems more efficient. The combination of underpinning science and breeding will improve productivity and fruit quality, reduce labour and optimise resource use.
