Norchief,a new smooth type,high total solids,red-skinned potato variety

Norchief is a medium late maturing, red variety with high total solids. In yield, the new variety is quite comparable to Red Pontiac and La Rouge but higher than Norland. Norchief has shown a certain degree of field tolerance to potato flea beetle,Epitrix cucumeris.     

Redsen: A new bright red-skinned potato cultivar

Redsen is a smooth, round, bright red-skinned potato cultivar with medium to high yield potential. It has resistance to race 0 of late blight (Phytophthora infestons) and is moderately resistant to some strains of silver scurf (Helminthosporium solanum) and common scab (Streptomyces scabies). The red color resists fading during storage and Redsen retains excellent marketability during storage.     

OAC Temagami: A new red-skinned white fleshed table potato cultivar

OAC Temagami is a new potato cultivar with red skin and creamy white flesh. Tubers are round in shape. When evaluated over three years at three sites in Ontario, it had higher specific gravity and culinary quality than Chieftain. OAC Temagami has the same maturity and comparable yield to Chieftain. It is recommended for fresh market use in Ontario.     

OAC Ruby Gold: A new red-skinned yellow fleshed table potato cultivar

OAC Ruby Gold is a new potato cultivar with red skin and yellow flesh. Tubers are oblong in shape. When evaluated over three years at three sites in Ontario, it had higher specific gravity and culinary quality than Chieftain. OAC Ruby Gold has the same maturity and slightly lower yield than Chieftain. It is recommended for fresh market use in Ontario.     

Alaska red: A general purpose,productive, red-skinned potato

‘Alaska Red’ is the first red-skinned potato bred and selected in Alaska as a clone suitable for the fresh potato market. Its parents are Alaska Clone 11-57-1-59 and ‘Red Beauty’. It is a high yielding, medium specific gravity potato with uniform skin and eye basin color, shallow eyes, uniform oval-to-flattened shape and is very attractive. The flesh is snowy white and remains white after boiling. Alaska Red keeps well in storage at 38°F (3.3°C). Scab of the tubers is the only disease that has been observed. In this subarctic region, flowers abort in the early bud stage. Red-skinned potato varieties available to Alaskan growers for the past quarter century have been unsatisfactory due to one or more of the following characteristics: low dry matter content, poor yield, uneven skin pigmentation and internal or external tuber cracking. Although consumers buy far less red than white-skinned potatoes, the demand brings Florida “reds” to Alaska as well as “reds” from other regions so that there is a year round outlet. Imported “reds” never approach the high quality of Alaskan grown “reds”. During the screening of seedlings, ‘Red Beauty’ was selected as a parental line because of its excellent conformation, skin color and eye arrangement. Low yield and shatter cracking made it unsuitable for commercial production. Alaska Red is a selection from seedlings of the cross Ak. 11-57-1-59 and Red Beauty made in 1965 and is the first red-skinned potato released from Alaska’s potato breeding. It was first evaluated by potato growers in 1972 and released in 1976 by the Agricultural Research Service, United States Department of Agriculture, Box AE, Palmer, Alaska 99645.     

Simcoe: A new early-maturing,chipping potato variety

Simcoe, a round, white, early potato variety with excellent boiling, baking and chipping qualities, was released by the University of Guelph, Agriculture Canada and the Ontario Ministry of Agriculture and Food in 1981. Yield is comparable to that of Norchip while the chip color ratings and specific gravity are higher. Simcoe is resistant to mild mosaic and late blight, moderately resistant to common scab and moderately susceptible toRhizoctonia. It is susceptible to virus leafroll but resistant to net necrosis from current season infection.
