Seed quality is one of the essential prerequisite for high yield formation. Ecological heterogeneity of seeds remains one of the unsolved challenges of seed production as yet. The existence of close relation between seed quality and the conditions of their growing indicates the relevance of the assessment of the ecological nature of seed heterogeneity and becomes the target of the authors’ study. Laboratory and field methods were widely used. The authors investigated different fractions of winter wheat seeds of the Alaya Zarya variety. The seeds were calibrated by width, by the specific weight, and by thickness. The studies have shown that seeds of different fractions differ in their ecological properties. Large seeds calibrated by width, seeds of low specific weight and seeds of shallow thickness were characterized by high responsiveness to vegetation conditions. The seeds of these fractions are recommended to be used in intensive cultivation technologies. The seeds of large fraction calibrated by thickness were characterized by high homeostatic properties and are recommended to be used in organic farming.
