Upstate New York Potato Variety Trials and Cultural Practice Experiments
Potato variety yield trials were conducted in four counties in upstate New York in 2010 in which a total of 49 named varieties and 183 numbered clones were evaluated. Eight replicated variety yield trials, two advanced observational trials, an organic study, and a potassium rate study were conducted at the Thompson Vegetable Research Farm at Freeville in Tompkins County on a Howard gravelly loam soil. Grower chip processing trials were conducted on mineral soils near Arkport (Steuben County) and Gainesville (Wyoming County). Grower red and white tablestock trials were planted on muck soil near Savannah (Wayne County) but were flooded out. All trials at Freeville and on grower cooperator farms were grown using standard commercial cultural practices. Trials at the Cornell research farm in Freeville were irrigated as needed. As evaluation of potato lines with golden nematode (GN) resistance is of high priority, 16 named and 36 numbered entries (33% and 20%, respectively) in these trials are known to have GN resistance (see Table 1 for attributes). Marketable yield, tuber quality and appearance, maturity, storage life and processing potential are among the important characteristics which are evaluated.
