Resistance of Glycine max x Glycine tomentella to Heterodera glycines. Nematropica. 35(2):61-62. Interpretive Summary: Technical Abstract: We tested 499 accessions of the perennial wild relatives of the soybean Glycine arenaria, G. argyrea, G. canescens, G. clandestina, G. curvata, G. cyrtoloba, G. dolichocarpa, G. falcata, G. latifolia, G. microphylla, G. pindanica, G. tabacina, and G. tomentella for resistance to Heterodera glycines race 3 (Hg Type 0). No reproduction occurred on 282 of the accessions. One of the G. tomentella accessions, PI 483218 (2n = 78), was immune to H. glycines and was selected to introgress resistance into the domesticated soybean, G. max (2n =40). Amphiploid mother plants were obtained and 50 clones were generated. These clones were evaluated for resistance to H. glycines, and all were immune. These results show promise in being able to incorporate a high level of resistance to H. glycines from perennial wild relatives of the soybean into G. max. |
