SUMMARY A laboratory method to inoculate seedlings uniformly with Gaeumannomyces graminis var. tritici is described. Resistance is defined via the rate of hyphal entry into the vascular tissue of host seedlings, and is measured by direct observation and by early stelar lesion development in seminal roots. The two scores for resistance are compared and evaluated, for infection with an isolate of low virulence. Evidence was obtained for resistance in the roots of wheat seedlings to G. graminis .
