Varieties used for comparison: 'S01-K8' and '90Y20'
Summary: The main stems of '90Y01 have a light tawny pubescence whereas those of 'S01-K8 have a brown (tawny) pubescence. When 50 % of the pods are ripe, the plants of '90Y01 are shorter than those of 'S01-K8. '90Y01 has a brown pod colour whereas it is tan for '90Y20. The seed shape of '90Y01 is elongate whereas it is spherical flattened for the reference varieties. The hilum colour of '90Y01 is imperfect yellow whereas it is black for 'S01-K8 and dark brown for '90Y20. '90Y01 matures earlier than the references varieties.

Origin & Breeding History: '90Y01 (experimental designations XB009E11, PH11002) is the result of a cross made in 2003 between 'YB01D05 and 'YB08K04 in Puerto Rico. The modified single seed descent method and pedigree method were used to develop the variety. The F1-F4 generations were grown in Puerto Rico. The F5 generation onward were grown in Minnesota, USA and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2008 in Chile. 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 iron chlorosis on calcareous soils.
Tests & Trials: Test and trials for '90Y01 were conducted in Goderich (Clinton), 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 201100212, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
