Origin & Breeding History: '91Y41' (experimental designations XB14Y10, PH10103) is the result of the cross between 'XB26P05' and '91M60' made in 2003 in Iowa, USA. F1 plants were grown out in Puerto Rico during the winter of 2003/04. The modified single seed descent method and pedigree method were used to develop the variety. The F2-F4 generations were grown in Puerto Rico, Minnesota and Chile. The F5 generation onward were grown in Canada and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2008. Wide area testing continued from 2008-2010 in the USA and Canada. Selection criteria included yield, maturity and resistance to Roundup branded herbicides.
Tests & Trials: Test and trials for '91Y41' were conducted in Goderich (Clinton), 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 201000561, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
