Synopsis Eight varieties, 6 resistant to net blotch and 2 susceptible, were used as parents in the genetic studies reported in this paper. Three genes for resistance— Pt 1 , Pt 2 , and Pt 3 —differentiated the six resistant varieties from the susceptible varieties, Atlas and Atlas 46. Pt 1 and Pt 2 were tightly linked with about 2.57% recombination; Pt 3 was inberited independently of the linked genes. The genes for net b'otch resistance were inherited independently of the Hanna gene for mildew resistance carried by Atlas 46.
