The World Oat ( Avena spp .) Collection (4,533 entries) was evaluated in replicated experiments in 1963‐64 for tolerance to soil‐borne oat mosaic virus, Marmor terrestre var. typicum and M. terrestre var. oculatum McK. In 1964‐65, 601 entries were repeated that scored less than 4 on a 0 to 10 rating (0 = no visual symptoms and 10 = completely susceptible or dead plants). Of these 601 entries, the 37 that scored less than or equal to 2.5 are listed. From this evaluation several excellent divergent sources of tolerance to soil‐borne oat mosaic virus were noted.
