Variety Description

Varieties used for comparison: '900Y71', 'Prius RR' and '900Y81'

Summary: '900Y61' flowers earlier than '900Y81'. When 50% of the pods are ripe, '900Y61' is shorter in plant height than 'Prius RR' and '900Y81'. '900Y61' has a brown pod colour while it is tan for 'Prius RR'. The seed shape of '900Y61' is spherical rounded while it is elongate for '900Y71' and '900Y81' and spherical flattened for 'Prius RR'. '900Y61' has a dark brown hilum while it is imperfect yellow for '900Y71'. '900Y61' matures earlier than '900Y81'. The protein content of the seed of '900Y61' is lower than in 'Prius RR'.

Origin & Breeding History: '900Y61' (experimental designations XB005C10, PH10001) is the result of a cross made in 2002 between 'XB01C03' and '90M60' in Chile. 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 was grown in Canada and the F4 in Chile. The F5 generation onward was grown in Minnesota and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2007 in Chile. Wide area testing continued from 2008-2010 in the USA and Canada. Selection criteria included yield, maturity, resistance to Roundup branded herbicides and to Phytophthora megasperma.

Tests & Trials: Test and trials were conducted in Monkton, 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 201000571, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
