Cornell University

Cornell University’s College of Agriculture & Life Sciences has a long and productive history as an institution known for successfully introducing novel plant varieties with improved disease and insect resistance and cold tolerance to the public.

Cornell Plant Varieties


Cornell’s potato breeding program centers around the genetic improvement of potato, both by conventional and molecular means. The highest breeding priority is to develop agronomically-acceptable varieties that are resistant to the golden nematode. It aims to develop new chipping and tablestock varieties that are adapted to the Northeast, and to meet ever-changing needs of the regional potato industry.

Chipping Varieties

White Skin White Flesh


Late maturity chipstock that produces attractive, round tubers. Specific gravity has averaged 0.004 less than ’Atlantic’. Excellent chip color from cold storage. Good resistance to common scab. Resistant to the golden nematode (Ro1). Previously tested as NY-139.


Late maturity chipstock. Large vines with white flowers. Tubers have scurfy skin with attractive round shape. Outstanding yield of large tubers. Generally free of pickouts due to external defects, small percentage of internal defects. Resistant to golden nematode and scab. Formerly test selection NY112.


Late maturity chipstock. Large tubers with attractive shape and moderately textured skin. In Cornell trials, yield has been comparable to ’Atlantic’, while gravity has averaged 0.01 less than ’Atlantic’. Few pickouts, but large tubers have shown 5 to 10% hollow heart. Very good chip color from 44 degree storage. Dormancy is six weeks longer than ’Atlantic’. Less susceptible to blackspot than ’Snowden’. Moderately resistant to common scab. Resistant to the golden nematode (Ro1). Previously tested as NY138.

Table-stock Varieties

White Skin White Flesh


Early to mid-season maturity white table-stock that features attractive large and oval tubers with a smoother skin than 'Superior'. Good resistance to common scab. Resistant to race Ro1 of the golden nematode. Previously tested as NY141.

'Upstate Abundance'

Early season maturity white table-stock that produces many small round tubers with smooth skin. Resistant to race Ro1 of the golden nematode. Some resistance to common scab and late blight. Previously tested as NY150.

Cornell Potato Express Licensing

Uihlein Farm of Cornell University is the official seed potato farm in New York State. This facility is used to develop disease-free nuclear seed stocks through pathogen-testing of seed originating from tissue cultured plantlets. Once you are licensed, please contact Uihlein Farm if you need a source for disease-free nuclear seed stock.
