Interpretive Summary: Soybean cyst nematode (SCN; Heterodera glycines) is a widely occurring and damaging pathogen of soybean that limits soybean production. Soybean resistance to SCN is somewhat limited, but may be more common in perennial Glycine species. The objective of this study was to evaluate perennial Glycine species for SCN resistance. In the first experiment, 223 plant introductions (PIs) of G. tomentella were inoculated with SCN. In the second experiment, 59 PIs representing 12 perennial Glycine species were inoculated with SCN. In the third experiment, 36 PIs representing 12 perennial Glycine species were inoculated with SCN. Of the total of 223 G. tomentella PIs evaluated, 86 were classified as resistant to three populations of SCN. In experiment two, only PIs of G. argyrea and G. pescadrensis were classified as resistant to all three SCN populations. In experiment three, 35 PIs (at least one PI in each of the 12 perennial Glycine species) were classified as resistant to one SCN population with 16 PIs showing no cyst reproduction. The perennial Glycine species have high levels of resistance to SCN, which could be used in genetic studies and mining SCN resistance genes for use in soybean. This information may be useful to those interested in developing SCN resistant varieties in soybean.

Technical Abstract: Soybean cyst nematode (SCN; Heterodera glycines; HG) is a widely occurring and damaging pathogen of soybean that limits soybean production. Soybean resistance to SCN is somewhat limited, but may be more common in perennial Glycine species. The objective of this study was to evaluate perennial Glycine species for SCN resistance. In the first experiment, 223 plant introductions (PIs) of G. tomentella were inoculated with HG Types HG 0, HG 2, and HG 1.2.3. In the second experiment, 59 PIs representing 12 perennial Glycine species were inoculated with the same three HG types. In the third experiment, 36 PIs representing 12 perennial Glycine species were inoculated with HG type 1.2.3.4.5.6.7. Of the total of 223 G. tomentella PIs evaluated, 86 were classified as resistant to three HG types, 69 as resistant to two HG types, and 22 as resistant to one HG type. In experiment two, only PIs of G. argyrea and G. pescadrensis were classified as resistant to all three HG types. In experiment three, 35 PIs (at least one PI in each of the 12 perennial Glycine species) were classified as resistant to HG Type 1.2.3.4.5.6.7 with 16 PIs showing no cyst reproduction. Our results show that high levels of resistance to SCN can be found among the perennial Glycine species. This represents an untapped resource for use in genetic studies and for improving resistance to SCN in soybean.
