MARCH 2018 GERMINATION.CA 47 given variety are, or are not, working against the blackleg on a particular farm. If the variety a grower planted two or three years ago is still around and isn’t sporting one of the new labels for 2018 and the grower would like to know which resistance genes it contains, Lange notes that they could call the seed company and ask. He’s not sure if the company would be able to tell growers that informa- tion, but it would make records from years past more meaningful and enable growers to more quickly put improved management in place. As to whether listing of resistance genes will be applied for other crops and diseases in future besides black- leg in canola and Phytophthora root rot in soybeans, Tsai, Jurke and Lange all believe it will depend on the crop and the disease. “We know certain export markets are more sensitive than others for certain diseases,” says Tsai, “and these types of label- ling systems and initiatives not only help the grower level tackle impor- tant agronomic management issues but also have the broader effect of EXAMPLESOFNEWLABELS Example Variety Alpha: R (BC) The traditional R rating means average field performance of blackleg resistance was below 30% of Westar, the susceptible check. The additional BC designation means the variety contains the resistance genes Rlm2 and Rlm3. Example Variety Beta: MR (A) The traditional MR means average field performance of blackleg resistance was 30% to 49.9% of Westar check. The additional A means it contains the resistance gene LepR3 or Rlm1. Example Variety Charlie: R (CX) As an R rated variety, average field performance of blackleg resistance was below 30% of Westar check. CX means it contains the resistance gene Rlm3 and an unidentified major resistance gene.
