Jacqueline Lee is a potato variety released by Michigan State University in cooperation with the Michigan Potato Industry Commission.  The tubers have an attractive tuber type, with bright and smooth skin and a yellow flesh, typical of many European varieties.  The plants yield a heavy set of medium-sized (3-6 oz.), uniform tubers.  The maturity is medium-late, similar to Red Pontiac.  It is the only U.S. variety that has a high level of foliar resistance to late blight.  The variety is named for the daughter of the breeder.

The Jacqueline Lee tubers can be used for baking, mashing, and microwave cooking and have excellent taste quality similar to Yukon Gold.  These medium-sized, uniform, oval-shaped tubers of Jacqueline Lee offer a unique type that could lend itself to the specialty variety market, such as farm and road-side markets.

The development and testing of Jacqueline Lee was supported in part by the Michigan Agricultural Experiment Station, Michigan Potato Industry Commission and the USDA Special Grant for Potato Breeding/Variety Development.

Michigan Purple is a purple-skinned tablestock variety developed at Michigan State University. The tubers have an attractive, round shape and a strong iridescent purple skin.  The tuber flesh is a brilliant white with excellent internal quality and does not darken after cooking.

Michigan Purple is the first variety released in the US with this unique appearance of purple skin and bright white flesh.  Under irrigated conditions the yield is high and has mid-early vine maturity.  Plant Variety Protection is underway for Michigan Purple.

The Michigan Purple tubers can be used for baking, mashing, and microwave cooking and have excellent taste quality.  The purple-skinned, white-fleshed tubers of Michigan Purple offer a unique type that could lend itself to the specialty variety market, such as farm and road-side markets.

The development and testing of Michigan Purple was supported in part by the Michigan Agricultural Experiment Station, Michigan Potato Industry Commission and the USDA Special Grant for Potato Breeding/Variety Development.

Liberator


A Round White Chip-processing Variety
with Resistance to Potato Common Scab

East Lansing, Michigan  48824

Liberator is a round white chip-processing variety with a medium set of bright-skinned tubers similar in appearance to Norchip.  The primary strength of this variety is its strong resistance to scab (Streptomyces scabies Thaxter) combined with chip-processing quality and high specific gravity.  Liberator was evaluated as seedling number MSA091-1.  The name Liberator was chosen to acknowledge the resistance to scab.

The tubers will chip process out-of-the-field and from 10°C (50°F) storage.  Liberator performed well in the North Central Regional Trials and the National Snack Food Association Trials.  Under irrigated conditions the yield and specific gravity are similar to Snowden.  Liberator has a full-season vine maturity that is similar to Snowden and tuber dormancy equal to Atlantic.  Plant Variety Protection is being sought for Liberator.

Liberator responds well to irrigation.  Spacing and nitrogen management is similar to Atlantic.  Hilling should be optimized for the tight tuber set, close to the stem.

The development and testing of Liberator was supported in part by the Michigan Agricultural Experiment Station, Michigan Potato Industry Commission and the USDA Special Grant for Potato Breeding/Variety Development.

Bt-Spunta

(also called SPUNTA-G2)

Bt-cry1Ia1 LINE WITH RESISTANCE TO
POTATO TUBER MOTH

East Lansing, Michigan  48824


The potato tuber moth (Phthorimaea operculella Zeller) is a primary problem facing potato farmers in developing countries. Currently, the only available means to control the potato tuber moth (PTM) and avoid major crop losses is the use of chemical pesticides. Michigan State University (MSU), funded by the U.S. Agency for International Development (USAID) through its Agricultural Biotechnology Support Project (ABSP), initiated biotechnology research on the development of PTM resistant varieties. A Bacillus thuringiensis (Bt)-cry1Ia1 gene, was obtained from ICI Seeds (now Syngenta seed company) and successfully introduced into the potato variety Spunta. Transgenic lines were shown to have a high level of resistance to tuber moth.

A Bt-Spunta line with commercial potential has been identified through collaborative research between MSU and research institutions in Egypt and South Africa. In 2003, MSU and its South African partner, Roodeplaat Vegetable and Ornamental Plant Institute (VOPI) started to collect the necessary data for commercial approval in South Africa with the aim of distributing the best line to potato farmers. Bt potato lines have been tested for multiple seasons, and have been found to be efficacious in the field and in storage. The South African government is supportive of biotechnology applications and has since 1997 deregulated Bt cotton, Bt maize and herbicide tolerant soybean. The benefits of the Bt potato to the farmer and end-users will be reduced input costs (less insecticides used), increased marketable yield, improved quality, reduced post-harvest losses, reduced human exposure to pesticides, and less pesticide residues on potato tubers.
