To develop potato cultivars that are genetically superior for adaptation, yield and grade

targeting the fresh and processing markets

Overall Goal

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

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

Impact and Output: New WI Releases

Breeding Objectives 70, 656 clones were planted in Year 1:

Clones received from US and Can Breeding Programs

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).

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.

WI Specific Gravity in USPB/SFA-North Lelah (W2717-5) vs. Snowden

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
