Origin & Breeding History: '93Y22' (experimental designations XB31G10, PH10304) is the result of a cross made in 2005 between 'ZB28S05' and '93M11' in Illinois, USA. The modified single seed descent method and pedigree method were used to develop the variety. The F3-F4 generations were grown in Chile and Illinois 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 2008-2010 in the USA. Selection criteria included yield, maturity, resistance to Roundup branded herbicides, to Phytophthora megasperma, Soybean Cyst Nematodes and Brown Stem Rot.

Tests & Trials: Test and trials were conducted in Wallaceburg, 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 201000474, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
