Varieties used for comparison: '92Y80', '93Y20', '93Y02' and 'RJS 31004'
Summary: '93Y05' has a weak intensity of anthocyanin colouration of the hypocotyl while it is strong for '92Y80' and '93Y20'. '93Y05' flowers later than '92Y80' and '93Y20'. The plant height of '93Y05' is slightly shorter than '93Y20' and 'RJS31004'. '93Y05' has a greater 100 seed weight than 'RJS31004'. The hilum of '93Y05' is black while it is dark brown for '92Y80'. '93Y05' matures later than '92Y80', '93Y20' and '93Y02'. The protein content of the seed of '93Y05' is less than '92Y80'.

Origin & Breeding History: '93Y05' is the result of a cross between 92B12 x 93M51 that occurred in 2003 in Iowa. Bulk, modified single seed descent and single plant selection methods were used in developing the variety. It was evaluated in yield test nurseries from 2005 to 2009. Contra season nurseries were used to advance the development of the variety. Selection criteria included yield, maturity and pest and disease resistance.
Tests & Trials: Tests and trials were conducted during the 2010 growing season in Wallaceburg, Ontario. Plots consisted of 2 rows with a row length of 3.8 meters and a row spacing of 76.2 cm. There were 3 replications. Tests and trials were supported by the purchased test report number 201000119 from the Plant Variety Protection Office, Beltsville, Maryland, USA.
