Varieties used for comparison: 'HS22RYS03' and '92Y31'
Summary: The intensity of the anthocyanin colouration on the hypocotyl is strong for '92Y32 whereas it is of medium intensity for 92Y31. '92Y32 flowers later than the reference varieties. The plants of '92Y32 have a light tawny pubescence whereas those of 'HS22RYS03 have a grey pubescence. When 50 % of the pods are ripe, the plants of '92Y32 are taller than those of the reference varieties. The seed shape of '92Y32 is elongate whereas it is spherical flattened for the reference varieties. The hilum of '92Y32 is black whereas it is imperfect black for 'HS22RYS03 and grey for 92Y31. '92Y32 matures later than the reference varieties.

Origin & Breeding History: '92Y32 (experimental designations XB23K11, PH11202) is the result of a cross made in 2005 between 'ZB28S05 and '93M13 in Iowa, 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. The F3 generation onward were grown in Illinois, USA 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 '92Y32 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 201100193, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
