Soybean Cyst Nematode Management Is Improved by Combining Native and Transgenic Resistance.

Field trials were conducted to assess the benefit of combining a transgenic soybean cyst nematode (SCN) resistance trait, Cry14Ab-1 expressed by the event GMB151, with the native resistance allele from PI 88788. The GMB151 event and were crossed into common genetic backgrounds and segregated out to create four genetically related lines within each background. The lines created contained both native and transgenic resistance ( + GMB151), only native resistance ( alone), only transgenic resistance (GMB151 alone), or neither resistance type (susceptible).
