New donors of short-stem dominant characteristic Gnom 1 (G1), Gnom 2 (G2), Gnom 3 (G3) have been created to the purpose of further increasing the yield of Winter Rye and effective redistribution of assimilation products to the benefits of the grain. Genetic and Statistical analysis of 10 selective characteristics of these donors has been conducted and options to improve them were determined. Application of G1 in the prospective breeding programs G1 on 10 characteristics would not create considerable difficulties. Engagement in the crossing of G2 and G3 donors may create complications in the expression of- productivity characteristics of the ear and plants in the progenies. Crossing used in transgress and combinative breeding is preferable for applying. Application of G3 may be accompanied with technical inconvenience in perfor-ming directed crossing. Application of G3 attracts by the creating conditions for uniting desirable height of plant with the constitutionnal components of Winter Rye productivity.
