To assist in developing improved forest material with a reasonable level of tolerance by discussing and exchanging selection and breeding strategies for durable disease resistance.

Primary activities

  • Increase exchange between research organizations on disease-resistant improved forest planting material
  • develop protocols in order to reduce the risk of introduction of new pathogens into new areas by importing reproductive material (cuttings, seeds)
