Origin & Breeding History: '92Y12' (experimental designations XB21D10, PH10201) is the result of a cross made in 2003/2004 between '92M72' and '92M51' in Chile. The modified single seed descent method and pedigree method were used to develop the variety. The F1 was grown in Canada. The F2-F3 generations were grown in Hawaii and advanced based on yield for single plants and then progeny row tests. The F4-F5 generations were grown in Canada in 2005 and 2006 with a contra season nursery in Chile in 2005/2006. Single plant purification occurred in 2007 in Canada. Wide area testing continued in the USA and Canada from 2008-2010. Selection criteria included yield, maturity, resistance to Roundup branded herbicides, to Phytophthora megasperma 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 201000555, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
