The changes in the main indices for grain quality of hulled oats at fractionation for the development of the method for their regulation were studied. It was shown that the grains of various fractions of hulled oats is not equal by biochemical composition and technological qualities. Fractionation of the grain samples collected from homogeneous large batches of oats and carrying out of corresponding analyses allowed the determination of a broad range of quality indices of individual fractions and their dependence on the thickness of the caryopsis. Then, by the correct selection and installation of top and (or) bottom sieves on seed cleaning machines of secondary cleaning, one can change (increase or decrease) the basic quality indices of a batch of grain from hulled oats up to values regulated by the State Standard or standards demanded by the consumer.
