SrEC (McIntosh et al., 1974).
6DL (Dyck and Kerber, 1977b); 6DS (Zeller and Oppitz, 1977); Sr29 appeared to be genetically independent of the centromere (Dyck and Kerber, 1977b).
Low Infection Type
1 to 3.
Low (Roelfs and McVey, 1979).
Common wheat. Sr29 appears to be a gene of European origin.
Roelfs and McVey (1979) reported that a few avirulent cultures gave low infection types that were slightly higher than usual. Huerta-Espino (1992) reported virulence only among cultures from western Asia, eastern Europe, Egypt, Ethiopia and Turkey.

Use in Agriculture
Adult plants with this gene are moderately susceptible (Roelfs and McVey, 1979). The gene has been used for stem rust control in European wheats, but has not been incorporated into North American winter wheats or spring wheats grown outside of Europe.
