  1. Maine Potato Breeding Program Gregory Porter, Paul Ocaya, and Tammy Mills, University of Maine, Orono Examples reds and specialty clones 2nd-year russet selections, 2010 New 60-hill seed plots; 3rd-year clones

  2. University of MainePotato Breeding Program • Research Effort by Type: • 60% russets and long-whites, processing and dual-purpose • 30% round types for chipping and/or fresh use • 10% reds and specialty types Greenhouse Crossing 2011 crosses produced 25,000 true potato seed (TPS) from 61 different families

  3. University of MainePotato Breeding Program • Top Priority Disease Resistance Goals • Late blight resistance • Scab resistance • PVY resistance • Pink rot resistance • Others: PLRV/NN, EB, VW, GN, Fusarium, etc Resistance Screening Plots, Clockwise from top: late blight, PLRV, PVY

  4. Selection of Late Blight Resistant Potato Varieties • 2011 Aroostook Research Farm: • Non-inoculated • 45 test clones, 9 standards • 18 were MR to R • 2011 Penn State: • Inoculated • Replicated, 45 test clones, 17 were MR to R • Single Replication, Observation, 77 of 215 were MR to R AF3317-15 Katahdin 2011 Late Blight Resistance Screening

  5. 2011 Seedling Tuber Production 65,420 greenhouse seedling tubers were produced at Aroostook Research Farm 25,898 “A” tubers (ME) from 115 families 22,896 “B” tubers (to ID, CO) 16,626 “C” tubers (to WI, ND) Seedlings produced from true potato seed Seedling Tuber Harvest, 2010: Liza Buck, Megan Ireland, Karlee Bernier, Chandler Guerrette, Samantha Fuller, Carol McKnight

  6. 2011 Field Selection in Northern Maine • 45,244 single-hill plots were evaluated consisting of seedlings from ME, ID, WI, ND • Selected for further evaluation in 2012: • 480 russets and long-whites (40%) • 545 whites, yellows, and chippers (46%) • 161 red- and purple-skinned (14%) Field Selection in Northern Maine

  7. University of MainePotato Breeding and Variety Development Disease, pest, and quality screening NCPT, NFPT, NE1031 & Other Multi-site testing GH Crosses produce TPS GH Seedlings produce seedling tubers 1st Field Season: Single-hill plots ~45,000 clones 2nd Field Season: 8- or 12-hill plots ~1,200 clones 3rd Field Season: New 60-hill plots ~300 clones 4th Field Season: 100-hill plots ~75 clones NC, FL, NY early selection Cooperator Selection 5th Field Season: 300-hill plots ~35 clones MSPB or elsewhere Clean-up & Pre-nuclear Seedling tuber exchange with USDA-ARS Idaho, ND, CO, and WI Small-scale Industry Trials 6th Field Season: 800-hill plots ~20 clones N1 and N2 Production Commercial- scale Industry Trials 7th Field Season: 800-hill plots and AF certified seed Commercial Seed Production Commercial Release

  8. 2011 Advanced Selections • Nineteen of thirty-three advanced selections (6th year and older) were selected to continue development during 2012: • 10 russets and long-whites (53%) • 7 whites and chippers (37%) • 2 yellow-fleshed (10%) Selected Advanced Clones, 2011 (AF0338-17, AF3001-6, AF3362-1, AF2574-1)

  9. AF0338-17A high yielding white for out-of-field chipping and fresh market • Primary Strengths: • High yields • Chips from the field • Wide adaptation • Good size profile • Much less internal heat necrosis and hollow heart than Atlantic • VW resistance • Known Weaknesses • MS to common scab • Not a storage chipper AF0338-17 Atlantic Chips, Late August 2010, New Jersey

  10. AF3001-6A high yielding long white with good processing quality • Primary Strengths: • High yields • Wide adaptation • Very good fry color • Good tuber type • Good internal quality • VW resistance • Known Weaknesses • Typically white netted, not russeted • MS to common scab • Tuber blight in 2011

  11. AF3362-1A high yielding, dual-purpose russet • Primary Strengths: • High yields • Mid-season maturity • Good fry color • Good tuber type and F-G appearance • Very little HH to date • Bruise resistance • Moderate scab resistance • Known Weaknesses • Internal heat necrosis in NJ and PA trials • Short tuber dormancy

  12. AF2574-1(University of Maine Potato Breeding; AF2153-2 x bulk pollen) • Late blight resistant, fresh market, oblong-round white • Sizing: good size profile • Vine maturity: late • Yield: VH • ~120% of standard whites • Spec Grav: M • 1.079 (vs 1.090 for Atl) • Fair to good boiled & baked • Appearance: F-G, variable • Externals: M • 12% vs 12% for Atl • Sunb, mshp, grck • Internals: • HH: L (1% vs 10% Atl) • IHN: L (much less than Atl) • Blackspot: MS to MR • Resistances: R to Net Necrosis; MR to R (LBL, EBL) S to MS: scab, pink rot, VW

  13. Reds and Specialty Varieties • Reds • Dakota Jewel, Modoc, Mazama, Red Maria, Red Sunset, B2152-17 • More to come ….. • Specialty • Lehigh (YF) • Yukon Gem (YF) • Peter Wilcox (purple-skinned, yellow flesh) • Adirondack Red, Adirondack Blue • More to come ….. AF4659-12 AF4545-1 AF4550-2

  14. Breeding Program Collaborations • Parents for Crossing Program • All U.S. Programs and many others; especially Cornell, USDA-ARS Beltsville, and USDA-ARS Aberdeen • Seedling Tuber Exchange and early screening • ME, USDA-ARS Aberdeen, ND, WI, CO • NC, FL, and NY • Advanced Clone Screening and Development • NY, USDA-ARS Beltsville, Tri-state programs, other programs as interesting materials become available • Michigan State (started in 2010) • SolCapProject • USPB National Chip and Fry Processing Trials (NCPT, NFPT) • Grant Proposal Collaborations • USDA-NIFA Special Grant (FL, NC, VA, MD, NY, PA, OH) • USDA-SCRI Acrylamide Project (WI lead, many states)
