  1. 1. The quest to find superior avocado rootstocks (AV07008) Danielle Le Lagadec & Terry Campbell Queensland Primary Industries and Fisheries VC project: Simpson Farm Pty Ltd & Birdwood Nursery
  2. 2. Queensland Primary Industries and Fisheries Aim Identify superior rootstocks that have been excluded from existing Australian rootstock trials Trial site • Established in 2004 in Childers, Central Queensland • Trial extends over 4 ha • 11 rootstocks with Shepard as scion & 33 rootstocks with Hass as scion • Five replicated plots of three trees each per rootstock with a guard tree between each plot © The State of Queensland, Department of Employment, Economic Development and Innovation, 2009
  3. 3. Queensland Primary Industries and Fisheries Trial site • Deep well drained red soils with low Pc pressure • Standard farm management practices Trial monitoring • Yields per tree, by mass and fruit number • Fruit quality assessments after cold storage • Tree health ratings in July (pre-flowering) • Graft compatibility rating • Measure tree vigour © The State of Queensland, Department of Employment, Economic Development and Innovation, 2009

  18. 18. Queensland Primary Industries and Fisheries Conclusions • Seedling rootstocks – Ashdot appear to be a dwarfing rootstock with both Hass and Shepard as scion, – Ashdot produced the highest yield and was the most productive rootstock • Clonal rootstocks – BC62 has consistently produced the highest yield for the past 4 season and is the most vigorous tree © The State of Queensland, Department of Employment, Economic Development and Innovation, 2009
  19. 19. Queensland Primary Industries and Fisheries Acknowledgments • Sincere thanks to: – Birdwood Nursery, Simpson Farm Pty Ltd, QDPI and HAL for their financial support – To Simpson Farm Pty Ltd for maintaining the trees and for providing the labour for the harvest – Rachael Langenbaker and the staff of the Bundaberg Research Station for their technical help © The State of Queensland, Department of Employment, Economic Development and Innovation, 2009
