Origin & Breeding History: '90Y90' (experimental designations XB09F10, PH10008) is the result of a cross made in 2002/2003 between '92M22' and '90M60' in Puerto Rico. The modified single seed descent method and pedigree method were used to develop the variety. The F2-F4 generations were grown in Puerto Rico. The F5 generation onward were grown in Minnesota and Canada and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2007/2008 in Chile. Wide area testing continued from 2009-2010 in the USA and Canada. Selection criteria included yield, maturity, resistance to Roundup branded herbicides and to Phytophthora megasperma.

Tests & Trials: Test and trials were conducted in Monkton, Ontario during the 2011 growing season. Plots consisted of 2 rows with a row length of 4 meters and a row spacing of 76 cm. There were 3 replicates. Results were supported by the official technical examination report 201000563, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
