Interpretive Summary:

Technical Abstract: Approximately 30 wild annual soybean, Glycine soja, accessions and 170 accessions of the perennial species, G. arenaria, G. argyrea, G. canescens, G. clandestina, G. curvata, G. cyrtoloba, G. falcata, G. latifolia, G. microphylla, G. pindanica, G. tabacina, and G. tomentella were evaluated for resistance to Heterodera glycines race 3. Most of the G. soja accessions evaluated were susceptible to H. glycines. A few accessions expressed a low to moderate level of resistance that is not adequate to use for resistance to H. glycines. All of the perennial soybeans had at least one accession that was immune to H. glycines. Differences in chromosome numbers between perennial soybean (2n = 38, 40, 78 or 80) and domestic soybean, G. max (2n = 40), require embryo rescue procedures to incorporate resistance in perennial soybean into G. max.
