2. Picking a Winner in the UK !  Task Identify and select varieties for the U.K. market  Elsoms Sites Six U.K. Trial locations Five are co-located with Official trials Three specific disease testing locations in the U.K. 1.LLS Specific nurseries - EW region & Scotland 2.Canker: specific nurseries in the EW region 3.Club root: specific nurseries - U.K. + Europe 1

3. Yield 2 Data on all slides in the presentation is taken from the HGCA Candidate list for England and Wales and where appropriate from the Full Recommended list 2013. For both Candidate and Recommended lists the control varieties are the same, DK Cabernet, Excalibur, Vision and Flash. The RL data is a 3 or 4 year mean. The Candidate list data is a 2 year mean. There will be slight variances in the results for the control varieties between the two lists due to the difference in years used to calculate the means.
