2. Overall Goal
To 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 WI
and 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
7. To develop potato cultivars, especial consideration
is given to the selection of parents to be used in
crosses
Cold Chipping High Solids Scab Resistance Late Blight-Resist PVY-Resist
French Fries
8. Breeding Objectives
70, 656 clones were planted in Year 1:
Clones received from US and Can Breeding
Programs
9. 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).
10. Early Clone Selection Strategies

• 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).
11. 2012 Follow Up to Early Clone Selection
1000+ clones Year 2 and 3 of the russet and chip types
are stored at 45°F and will be evaluated for processing
traits (specific gravity/fry quality) in late January or early
February.
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 tested
and are being evaluated for processing traits.

Data: V. Currie, A. Sullivan, U. of
22. 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
