'NY138' has a medium number of medium sized red-violet flowers whereas there are few and small sized white flowers in the reference variety. The anthocyanin colouration of the corolla and of the peduncle of 'NY138' is stronger than the reference variety. The tuber of 'NY138' is elliptical with a light beige smooth skin colour whereas it is round with a chamois rough skin colour for 'Snowden'.

Origin & Breeding History: The potato clone 'NY138', previously evaluated as Y18-16, resulted from a cross made in early 1998 between the chipping varieties 'Marcy' (female parent) and NY115 (male parent) at Cornell University. Seed from this cross was first sown in 1999 and transplanted on Mount Pleasant, near Ithaca, New York. Traits that were used for selection were the ability to chip directly from 44F cold storage, freedom from internal and external physical defects, resistance to scab, resistance to golden nematode, specific gravity, maturity, and yield.

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