DIVERSIFOOD Final Congress - Session 6 - NOVIC - Bill Tracy

  1. 1. NOVIC: A Participatory Project to Trial and Breed Vegetable Varieties for Organic Systems Jim Myers1, Bill Tracy2, Micaela Colley3, Michael Mazourek4, Julie Dawson2, and Erin Silva2 1 Oregon State University, United States, 2 University of Wisconsin-Madison, United States, 3 Organic Seed Alliance, United States, 4 Cornell University, United States,
  2. 2. Background pre-2000 North America •  Continued consolidation of seed companies •  Investment in most valuable crops •  Elimination of many traditional varieties. •  Elimination of breeding effort on many traditional crops Percent of Harvested Field Crop and Vegetable Land in Corn and Soybean
  3. 3. Background pre-2000 North America •  Continued consolidation of seed companies •  Investment in most valuable crops •  Elimination of many traditional varieties. •  Elimination of breeding effort on many traditional crops •  Abandonment of the margins
  4. 4. Background post-2000 North America •  Abandonment creates new opportunities •  New farming systems – organic, MIRG •  New niches for startup seed companies •  Public breeders, NGOs •  Organic breeding. •  Education
  5. 5. Northern Organic Vegetable Improvement Collaborative •  The overall goal of NOVIC is to increase the proportion of U.S. agriculture that is managed organically. 1.  Developing new vegetable varieties for organic agriculture. 2.  Conducting variety trials with farmers in real farm conditions 3.  Improving the ability of farmers and seed producers to grow and breed organic seed
  6. 6. Northern Organic Vegetable Improvement Collaborative – Current PIs
  7. 7. NOVIC is developing new vegetable varieties for organic agriculture.
  8. 8. NOVIC Varieties •  Since 2009 •  12 varieties have been released to seed companies •  10 are pending •  Broccoli, Butternut squash, Sweet corn, Tomato, Cabbage, Snap Peas, Snow peas, Delicata squash, Peppers
  9. 9. NOVIC is conducting variety trials with farmers in real-world conditions.
  10. 10. NOVIC is improving the availability of farmers and seed producers to grow organic seed.
  11. 11. Thirteen graduate students trained in organic plant breeding
  12. 12. Participatory Sweet Corn Breeding Martin Diffley Farmington MN, John Navazio OSA, Bill Tracy, Jared Zystro, Adrienne Shelton UW-Madison Martin wanted •  Excellent eating quality •  Sugary enhancer (su1 se1). •  Good germination. •  Direct seeding. •  Good resistance to rust and smut. •  Early vigor (weed competiveness). •  Dependability. •  Availability.
  13. 13. •  Good farmers know what they need to be successful. •  Plant breeders can work with them to achieve their goals. •  In a participatory model •  Indirectly using the information gained from them in influencing the breeding objectives. •  But sometimes farmers don’t know what is possible. •  The farmer is the expert on the crop and cropping system. •  The breeder needs to be an expert on the species
  14. 14. Summer; selection at Farmington 100 families in each of two pops 15% selection intensity Five cycles of full sib recurrent selection Winter; recombine selects in Chile
  15. 15. Gain from Selection Trials Question What gains have we made from our cycles of selection? Experimental Design Randomized Complete Block Design (RCBD) 4 organic environments: Madison and Arlington, WI in 2012 and 2013 4 replications per environment 4 row plots Entries Cycles 0-5 of each population (early and late) Traits of interest Agronomic and eating qualities, disease resistance, germination
