PBG 519 – SP2013 Lauren Magalska Ryan Graebner Jason Lattier Hazelnut Breeding Program Profile 1. Description of the plant(s) a. Hazelnuts are wind-pollinated, monoecious, dichogamous trees with sporophytic incompatibility. b. Economic importance to Oregon, the nation, the world i. Oregon is the center of hazelnut production in the United States. Oregon represents 99% of the of hazelnut production in the US, and 3-5% of the worldwide. Currently, the industry is has a net income of $44 million/year and covers 28,400 acres with about 3,000 new acres being planted each year. ii. The United States produces about 7% of the world’s hazelnuts. iii. Approximately 850,000 metric tons are produced annually throughout the world. 2. Rationale and program goals a. Why breed this plant at OSU? i. While OSU has released varieties resistant to Eastern filbert blight (EFB), new strains could be introduced from the eastern United States, and could potentially overcome resistance genes in the current varieties. ii. In Oregon, due to differences in markets and a focus on mechanized harvesting, growers need varieties that produce larger hazelnuts, that more easily fall from the tree. These traits must also be considered in making new crosses. b. Summary of short, medium, long-term goals i. Obtain new sources of resistance to EFB. ii. Introduce new cultivars that are adapted to Oregon's climate and harvesting techniques. 3. Current Research Projects a. Focus - To develop new cultivars for Oregon’s hazelnut industry by improving quality traits for the kernel market and improving resistance to eastern filbert blight b. Breeding method(s) i. Typically seedling flowers after 5 years ii. 8 year seed to seed cycle iii. Marker-assisted selection methods using robust DNA markers linked to the dominant resistance allele from 'Gasaway’ iv. Utilize new germplasm from hazelnuts collected around the world and evaluate novel hybrids v. Evaluate interspecific hybrids of Corylus americana × Corylus avellana for adaptation to eastern North America c. Sponsors i. Oregon State University Agricultural Research Foundation ii. Oregon Hazelnut Commission iii. State of Oregon iv. Hatch Act v. USDA Specialty Crops Research Initiative d. Collaborators i. Washington State University ii. Rutgers University iii. University of Nebraska at Lincoln iv. University of Missouri v. National Arbor Day Foundation vi. Donald Danforth Plant Science Center vii. USDA-ARS National Clonal Germplasm Repository 4. Graduate student training a. PI statement of expectations for grad students i. Students must demonstrate a passion for plant breeding and show interest in all aspects of plant breeding (i.e. field, lab and green house work) ii. Meet department admission requirements iii. Quantitative GRE score ~70% or above iv. Work part time on own research and part time on other project v. Learn the whole program and participate in every aspect of work vi. Inherit previous work, make a contribution, and pass along to next grad student b. Current grad student projects i. - Develop, characterize and map simple sequence repeat (ssr) loci using 'Jefferson' repeats as the reference alligning with Illumina genome sequences (paired end) from the other seven accessions. - Study new sources of EFB resistance in hazelnut accessions - Seven Moscow Selection, Uebov, and 'Yodder#5'. c. Past grad student projects i. DNA markers and characterization of novel sources of eastern filbert blight resistance in European hazelnut (2013) ii.
