Variety Description

Varieties used for comparison: '92Y30', 'RJS29003' and 'CF60GR'

Summary: The hypocotyl of '92Y74' has a strong intensity of anthocyanin colouration while it is a medium intensity for '92Y30'. '92Y74' flowers earlier than 'RJS29003'. The pubescence of '92Y74' is grey while it is light tawny for 'RJS29003'. When 50 percent of the pods are ripe, '92Y74' is shorter than '92Y30'. '92Y74' has a tan pod colour while it is brown for '92Y30'. The hilum colour of '92Y74' is imperfect black while it is black for 'RJS29003'. '92Y74' has an elongated seed shape while it is spherical rounded for '92Y30' and spherical flattened for 'RJS29003' and 'CF60GR'. The 100 seed weight of '92Y74' is less than that of 'CF60GR'. '92Y74' matures later than '92Y30'.

Origin & Breeding History: '92Y74' (experimental designations XB28B10, PH10206) is the result of a cross made in 2004 between '92M70' and '93M11' in Iowa, USA. The modified single seed descent method and pedigree method were used to develop the variety. The F1 and F2 generations were grown in Puerto Rico. The F3-F5 generations were grown in Iowa and advanced based on yield for single plants, progeny rows and then multiple location trials. Single plant purification occurred in 2007/2008 in Puerto Rico. Wide area testing continued from 2008-2010. Selection criteria included yield, maturity, resistance to Roundup branded herbicides, to Phytophthora megasperma and soybean cyst nematodes.

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 201000552, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
