This article presents materials on the study of plant survival as a basic biological property characterizing the ability of seeds to create in specific conditions full-fledged plants participating in the formation of yield. Aspects of plant survival are considered depending on varietal characteristics and levels of mineral nutrition. The purpose of the research was to determine the survival rate of plants of different winter wheat varieties depending on the levels of mineral nutrition and to establish the relationship of this property with yield. As a result, it was found that the survival rate of winter wheat varieties, all other things being equal, practically does not depend on the levels of mineral nutrition. This indicator is integral, and depending on the variety, it is characterized by a different ability of seeds to create full-fledged plants in specific conditions. There is an interdependence between the survival rate of plants and the yield of winter wheat varieties, which is expressed as medium and strong, depending on the variety. 
Keywords: winter wheat, varieties, plant safety, plant survival rate, mineral nutrition, fertilizer.
