Origin & Breeding History: The potato clone 'NY129', initially evaluated as T11-2, resulted from a cross made in early 1994 between 'N38-1' (female parent) and 'ND2225-1R' (male parent). Seed from this cross was first sown in 1995 and transplanted on Mount Pleasant, near Ithaca, New York. Traits that were used for selection were intensity of red skin color, tuber shape, freedom from internal and external physical defects, resistance to scab, resistance to the golden nematode, and yield.

Tests & Trials: Tests and trials occurred during the summer of 2007 in Rawdon, Quebec. Sixty plants of each variety were in trial.
