Three donors for the dominant stem shortness in winter rye were developed. The genetic determination of the difference in a plant height for each donor was revealed. There were additive genes for the stem shortness in the donors Gnom 1 and Gnom 2 and dominant-epistatic ones in the donor Gnom 3. The investigation of genetic correlation between the number of quantitative traits and the plant height was carried out. On the basis of the data obtained, the strategy of using each donor for stem shortness in rye breeding was determined.
