Trial Discussion/Summary:
The site where the conventional and the IT lines were located became waterlogged at various times during the season. The area also became thick with waterweed. Despite this and the less than ideal soil type for canola the IT and conventional lines outyielded the TT lines that were not waterlogging affected. Through the season the TT lines appeared visibly healthier and better than the other lines but in most cases actually yielded lower.
Of the TT lines alone, Stubby, closely followed by CBWA's Tribune, led the yields.
