Four sets of wheat lines (representing early selections for Septoria resistance, cultivars used as parents in crosses, modern cultivars, wild relatives, and a nursery containing cultivars that had been screened extensively for resistance to Septoria tritici) were inoculated quantitatively with S. nodorum. Lines of Triticum fungicidum, T. timopheevi, and T. dicoccoides were most resistant. Among the few good modern lines of T. aestivum were EP-VOC-214 and CVL 2204/Y2375/BGL/TB/TB. Certain wheat lines appeared promising for use in accumulating additive resistance to Septoria.
