The work carried out by breeders in the last three decades has justified this approach. The losses in yield caused by rust fungi and other parasitic fungi have greatly decreased, though they are still considerable. The question of the resistance of various crops to rust fungi and the question of selection of resistant varieties were dealt with in the works of (1912), (1927), P. Luk'yanenko (1934, 1935, 1941), V. Bryzgalova (1935), V. Gulkanyan (1936, 1938, 1947), Shcherbak (1937), V. Zolotnitskii (1938, 1939). E. Geshele (1938, 1939, 1941), S. Syrovatskii (1938, 1939), V.
