Soybean cyst nematode (SCN; Heterodera glycines; HG) is a widely occurring and damaging pathogen that limits soybean production. Developing resistant cultivars the most cost-effective method for managing this disease. Genes conferring SCN resistance in have been identified; however, there are populations overcome known genes. In order to identify additional sources of potentially new genes, 223 plant introductions (PIs) G. tomentella 59 PIs 12 other perennial Glycine species were inoculated with HG Types 0, 2, 1.2.3, then 36 out set further evaluated Type 1.2.3.4.5.6.7, population overcomes all genes soybean. Of evaluated, 86 classified as three types, 69 two 22 one type. species, argyrea pescadrensis types. challenged 35 16 showing no reproduction. Our study confirms high levels among species. This represents an untapped resource use genetic studies improving
