Variety Description

Varieties used for comparison: 'DH3604', 'Nattawa', 'Heron' and 'Electron'

Summary: 'Loriot' has anthocyanin colouration of the hypocotyl while 'Electron' does not. The lateral leaflet of 'Loriot' is lanceolate shaped while it is pointed ovate for 'Nattawa'. 'Loriot' has a violet coloured flower while it is white for 'Electron'. The pod of 'Loriot' is tan coloured while it is brown for 'Nattawa' and 'Heron'. 'Loriot' matures later than 'Nattawa' and 'Electron'. The protein content of the seed of 'Loriot' is higher than 'Heron' but lower than 'Nattawa' and 'Electron'. 'Loriot' has a higher sugar content of the seed than 'Nattawa'. The 100 seed weight of 'Loriot' is higher than the reference varieties.

Origin & Breeding History: 'Loriot' (experimental designation OT06-23 and X4678-S-S-103) originated from the cross DH3604/Chikala. The final cross occurred in February 2000 in Ottawa, Ontario. The population was advanced using single seed descent to the F4 generation. The F4 population was grown in a field in 2001. Selected F5 progeny rows were harvested in bulk in 2002 and used for further testing. OT06-23 was tested at Ottawa and Nepean in 2003 and 2004. It was tested in multiple location trials since 2005. Selection criteria included seed size, adaptability and agronomic characteristics.

Tests & Trials: Trials were conducted during the 2010 and 2011 growing seasons at the Agriculture Agri-Food Canada, Eastern Cereal and Oilseeds Research Centre in Ottawa, Ontario. Plots consisted of 4 rows with a row length of 5 meters and a row spacing of 40cm. There were 4 replicates.
