The article presents the results of studies of quality variability of winter rye seeds of Chulpan 7 variety in the ear. The essential variability of seed quality of seeds within the ear has been established. The coefficient of seed quality index variation (germination energy, germination capacity and growth force) is 1.68-12.11%. The nature of the change in the mass of 1000 seeds, the germination energy, germination capacity and the growth force of seeds in the ear of winter rye is subject to a certain pattern. Seedlings from seeds of different parts of the ear according to morphological indicators (number of roots, length and mass of sprouts and roots) also differ among themselves. The quality of the seeds and their productivity is highest in the middle part of the ear and they gradually decrease to the base and apex of the ear.
