  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. • LLS Specific nurseries - EW region & Scotland • Canker: specific nurseries in the EW region • Club root: specific nurseries - U.K. + Europe

  3. Yield • 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.

  4. Gross Output – OP’s

  5. Gross Output – Hybrids (Trinity)

  6. Agronomy • 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.

  7. Establishing the Crop • Good autumn vigour • Strong rapid development • Robust autumn plant architecture • Good winter hardiness - not prostrate • Strong early spring growth reported from 2013 seed crops.

  8. Earliness – OP’s

  9. Earliness - Hybrids (Trinity)

  10. Plant Height – OP’s

  11. Plant Height - Hybrids

  12. Standing Power – OP’s

  13. Standing Power - Hybrids (Trinity)

  14. Disease Resistance • 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.

  15. Disease Scores – OP’s

  16. Disease Scores - Hybrids

  17. Verticillium Wilt • Not just a European disease….. • An increasing problem in the UK! • Dr Gladders’ recommendations for managing the risk were • Determine its prevalence on individual farms • Good agronomy – a strong plant holds off verticillium • Extended rotations • Variety choice • Trinity has good resistance – • Galileo parent has very good resistance • Trinity performed excellently in the Gottingen trials.
