Interpretive Summary: Soybean cyst nematode (SCN) is an important pest of soybean that reduces soybean yield world wide. Planting resistant varieties is a widely used method to control the nematode, but races of the nematode exist that can overcome all known sources of resistance used at present. About 500 accessions of 12 species of perennial relatives of soybean were evaluated to determine if they were resistant or susceptible to SCN 3, the most common race in the U.S. Almost 280 accessions were highly resistant or immune, that is allowed no nematode development. All the species except one had at least one accession that was immune to the nematode. The immune accession PI483218 of Glycine tomentella was used to make hybrids with the domestic soybean, G. max. Fifty clones were developed and all were immune to SCN race 3. These results are important because a new source of resistance to soybean cyst nematode has been developed and this source of resistance allows no reproduction of the nematode. This resistance will be useful to soybean breeders who are developing soybean resistant to SCN

Technical Abstract: Soybean cyst nematode, Heterodera glycines, is an important production limiting pest in major soybean production areas throughout the world. The primary component of H. glycines management is the planting of resistant cultivars in rotation with nonhost crops. Several genes that confer resistance to H. glycines have been identified, but populations of H. glycines that can overcome all of the genes are known. In order to find additional resistance genes, the perennial soybeans G. argyrea, G. canescens, G. clandestia, G. curvata, G. cyrtoloba, G. dolichocarpa, G. falcata, G. latifolia, G. microphylla, G. pindanica, G. tabicina, and G. tomentella were evaluated for resistance to H. glycines HG Tpye 0. All species except C. curvata had at least one accession that was immune to H. glycines. Glycine tomentella (accession PI 483218, 2n=78), which was immune to H. glycines, was used to introgress resistance into intersubgeneric hybrids of G. max (cv. Altona) and this G. tomentella accession. Fifty clones of amphiploid hybrid lines (2n=118) resulting from this hybridization were developed and when challenged with H. glycines HG Type 0, the clones also were immune to the nematode.
