2 The Quaker International Oat Nursery ObjectivesTo support oat breeding programs that are not well developed or lack the technical expertise, facilities, manpower, or other resources to effectively operate independently.To distribute improved and unique germplasm around the world so that yield, milling quality, disease resistance, and genetic diversity of oats are maximized in all participating oat breeding programs.To evaluate advanced lines and provide useful data to the originating breeders about agronomic performance and effectiveness of disease resistance in diverse environments.The Quaker International Oat Nursery
3 The Quaker International Oat Nursery Nursery CompositionPure lines for use as parents100 per year of the best lines available from cooperatorsDiverse program sourcesDisease resistanceQuality and agronomic traitsSegregating Populations for selection and development of lines150 per yearCrosses made by nursery coordinatorsCombine desirable traits from diverse lines not normally available to individual breeders

19 The Quaker International Oat Nursery We believe that it is essential that oat researchers continue to exchange ideas and germplasm, and to share intellectual and other resources if oats are to remain a viable crop worldwide.The Quaker International Oat Nursery is the foremost system of germplasm exchange in oats and serves as a model for other crops.
