Origin & Breeding History: 'Adirondack Red' originated from a cross between 'N40-2' and 'Q155-3', in early 1994. The traits which were evaluated most rigorously were uniformity of flesh colour, freedom from internal and external physical defects, maturity and yield.

Tests & Trials: Trials for 'Adirondack Red' were conducted in Drummond, New Brunswick in 2007. All entries were planted in single-row plots. Plots consisted of rows 22 meters long with 30 cm in row spacingbetween plants and spacing between rows of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
