In addition, these results suggest that the benefit transfer method can be effictively used in other states and on other enviornmental issues. The use of this method and the results fo the analyses can then be used to evaluate or develop soil conservation programs and technologies associated with those programs. LA407 inbred backcross population and to test for an association between molecular markers and resistance to bacterial canker type A and type C isolates. Map conserved motifs from plant resistance genes in the inbred backcross population and test for an association between these genes and resistance to bacterial canker in L. hirsutum LA407. This research project aimed to identify the number and location of genes that confer resistance in tomato to bacterial canker caused by Clavibacter michiganensis subsp.
Bacterial canker is a devastating disease of tomatoes in the Midwest.
Its symptoms include systemic infection, wilt, open cankers, marginal necrosis, stunting, and fruit spots. Past efforts to develop resistant tomato varieties have been slow due to a lack of knowledge concerning the inheritance of resistance in cultivated tomato and its wild relatives. Our research has resulted in the genetic characterization of two independent resistance genes relative to DNA based molecular markers. These genetic studies have helped us to understand why some plants resist disease and will provide tools for applied studies. The challenge was to develop environmentally safe strategies for bacterial disease of tomato.
