  • 1. Wisconsin Potato Variety Breeding Report – NCCC84 Meeting December 10-11, 2012 Felix Navarro, Kyle Rak, Bryan Bowen and Jiwan Palta ¹ Department of Horticulture ² Agricultural Research Stations
  • 2. Overall GoalTo develop potato cultivars that are genetically superior for adaptation, yield and grade targeting the fresh and processing markets
  • 3. Breeding Objectives (End Use)• Long Storage Chipping Lines (better than Snowden)• Early Chippers (potential Atlantic replacements)• Processing (French Fry) Russet Varieties• Fresh Market Russet Varieties• Fresh Market Red Skin and Specialty Varieties
  • 4. Analysis of Seed Acres Planted in WIand Adoption of New Potato Varieties Chipping clones: •Higher rate of adoption •More clones with potential success offered Fresh market/processing russet: •Not as many new choices •Several WI clones look good for the fresh market Red: •Not many new choices being tested on-farm. Yellow Flesh: •Several choices of varieties being tested and available
  • 5. Impact and Output: New WI ReleasesVariety Acres Entered for Seed Certification 2012 2011 2010 2009 2008 2007 2006 2005MegaChip 462 385 349 382 361 279 133 50Freedom Russet 13 56 108 128 112 103 60 35White Pearl 22 22 3 0 19 25 24 11Villetta Rose 11 22 9 7 21 18 67 69Tundra 18 1 <2 0 0 4 0 0Nicolet 111 55 20 5 0 2 0 0Accumulator 75 56 16 0 0 0 0 0Lelah 5W5015-12 2W6002-1R 1W6511-1R 1W6703-1Y 1W6703-5Y 1Acres WI lines 726 597 505 522 513 422 306 177Number WI lines 11 7 7 4 4 7 5 5
  • 6. To develop potato cultivars, especial consideration is given to the selection of parents to be used in crossesCold Chipping High Solids Scab Resistance Late Blight-Resist PVY-ResistFrench Fries
  • 7. Breeding Objectives 70, 656 clones were planted in Year 1:Clones received from US and Can Breeding Programs
  • 8. Early Clone Selection Strategies• Seedling tubers: seedling tuber interchanges to complement objectives• Year 1: tuber shape, color, skin texture, specific gravity (processing quality)• Year 2: Add Verticillium wilt, common scab, late blight, maturity, processing quality (fry quality, specific gravity): 1 loc (yield) + Disease locs• Year 3: Add Verticillium wilt, common scab, early blight, late blight, maturity, processing quality (fry quality, specific gravity) : 1 loc (yield) + Disease• Year 4 and 5: Detailed replicated yield + disease trials: 2 locs (yield) + 4 locs (replicated common scab, late blight, verticillium, collaborative work with CAN on sugar profiling). Clones are advanced to state, regional (NCRT) and national trials (NCPT, NFPT).

Clones are advanced to state, regional (NCRT) and national trials (NCPT, NFPT).
  • 10. 2012 Follow Up to Early Clone Selection 1000+ clones Year 2 and 3 of the russet and chip typesare stored at 45°F and will be evaluated for processingtraits (specific gravity/fry quality) in late January or earlyFebruary. They were already evaluated for external and internal qualityAdditionally, two new experimental populations , 1)Bannock Russet x Tundra (190 clones) , and 2) Liberator(scab resistant) x W4013-1 (110 clones) were field testedand are being evaluated for processing traits. Bannock Tundra Some Bannock x Tundra

  • 21. Lelah (W2717-5)Pedigree: Snowden x S440 Maintains chip quality at least a month longer than Snowden from 45-50°F. Specific gravity is similar to Snowden in average but more consistent (less variable) Better tuber shape and uniformity than Snowden. Field tuber yield lower than Snowden , but it is a choice as a chip-stock after 7-9 months in storage, when Snowden tuber yield = $0
