The paper deals with the use of chemical compounds in soft wheat breeding, the role of induced mutations in plant improvement. The paper presents the effects of fungicides influence on morpho-logical and population traits of soft wheat. Laboratory experiments revealed the effects of disinfect-ants, the concentrations of their active components and the period from treatment to the formation sprouts of soft spring wheat Pavlogradka. The effect of systemic fungicides Comfort, AltSil, Ter-rasil and Alcasar was studied whet applied at recommended dose and greater than twice the normal values. They were compared with control samples without treatment. The sowing qualities of treated seeds were unstable, morphological and population traits of wheat seedlings were not homogeneous.
