Origin & Breeding History: '92Y22' (experimental designations XB22P11, PH11201) is the result of a cross made in 2006 between '92M54' and '92Y30' in Illinois, USA. The modified single seed descent method and pedigree method were used to develop the variety. The F1-F2 generations were grown in Puerto Rico while the F3 was grown in Illinois. The F4 generation onward were grown in Chili and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2008 in Illinois. Wide area testing continued from 2009-2011 in the USA and Canada. Selection criteria included yield, maturity and resistance to Roundup branded herbicides, Phytophthora rot (Phytophthora megasperma f. sp. glycinea) and soybean cyst nematode (Heterodera glycines).

Tests & Trials: Test and trials for '92Y22' were conducted in Ridgetown, Ontario during the 2012 growing season. Plots consisted of 2 rows with a row length of 4 metres and a row spacing of 76 cm. Each plot was sown with approximately 225 seeds. There were 3 replications per variety arranged in a RCB design. The measured characteristics were based on 30 measurements per variety. Mean differences were significant at the 5% probability level based on LSD values. Results were supported by the official technical examination report 201100194, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
