AbstractSixteen advanced seedlings and newly named cultivars were compared with three standards in trials at the National Fruit Trials in southern England and the Scottish Horticultural Research Institute in eastern Scotland. The results are tabulated. All of the new cultivars produced vigorous cane growth which, to varying degrees, hampered hand picking and increased the risk of cane damage. The named cultivars and leading selections were all at least as good as the standard cultivars of comparable season, and in many cases were a considerable improvement upon these for fruit yield. Glen Esk and Delight consistently gave heavy crops of unusually large fruit.
