New prospects from the Scottish raspberry breeding programme.

摘要

Scottish raspberry production has undergone a dramatic transition in the last five years. After a sharp decline in acreage, beginning in the mid-eighties, production has now shifted from processing to the high value, high quality fresh market. The majority of fresh market production is sold to multiple retailers, where two cultivars, 'Glen Ample' and 'Tulameen', dominate sales. Changes have also occurred in cultivation practices, from outside field plantations to protected cropping systems. The Scottish raspberry breeding programme has rapidly responded to these changes by conducting part of the selection process under Spanish-style polytunnels, on-site at SCRI. This will help to identify suitably adapted germplasm for commercial trialing and eventual release. Two advanced summer-fruiting selections, suitable for both the fresh and processing markets, are currently undergoing commercialisation for the UK industry.
