Variety Description
Varieties used for comparison: 'SP Banner', '9550', 'SWJ8001RR', 'NR04-04769' and 'NR04-01675'
Summary: '9552' has fewer leaf lobes per leaf than that of '9550', 'SWJ8001RR', 'NR04-04769', and 'NR04-01675'. The margin dentation of '9552' is shallower and less dense than that of 'SWJ8001RR' and '9550'. '9552' has shorter leaves than 'SWJ8001RR'and narrower leaves than '9550'. At full flowering, the plants of '9552' are shorter than 'SWJ8001RR' and 'NR04-01675'. '9552' flowers earlier than 'SWJ8001RR' and 'NR04-04769'. The flowers of '9552' have shorter petals than those of 'SP Banner', broader petals than 'SWJ8001RR' and narrower petals than 'SP Banner'. '9552' has a wider silique than 'SP Banner' and '9550'. The silique beak of '9552' is shorter than '9550' and longer than 'SWJ8001RR' , 'NR04-04769' and 'NR04-01675'. 'NR04-04769. '9552' has dark brown to black seeds whereas those of 'SWJ8001RR' are red brown to black. At maturity, the plants of '9552' are shorter than those of 'NR04-01675'. Note than 'SP Armada' was also included as a reference variety, however it differs from '9952' mostly by its susceptibility to glyphosate.

Origin & Breeding History: '9552' (experimental designation NR04-04346) was developed by the Agriculture Research and Development Divison of Viterra in Saskatoon, Saskatchewan. The variety originated from a cross made in 2003. Segregating generations were selected for maturity, lodging resistance, and seed quality. Roundup herbicide was applied at several stages of development to further select for herbicide resistant lines.
Tests & Trials: Test and trials for '9552' were conducted during the summers of 2007 and 2008 in Rosthern, Saskatchewan. Plots consisted of 6 rows per variety spaced 20 centimeters apart with a row length of 5.5 meters. There were 4 replicates arranged in an RCB design.
