Two-components varietal mixtures of winter wheat (the susceptible cv. Senta, the cv. Vlada resistant to leaf rust race UN-3-61SaBa) were set up in the following variants: 1. R (resistant) = 100 %, 2. N (susceptible) = 100 %, 3. R:N=50:50 %, 4. 2R:N=6.7:33.3 % 5. R:2N=33.3:66.7 %, 6. 3R:N=75:25 %, 7. R:3N=25:75 %. Plants were inoculated with urediospores of Puccinia recondia var. tritici, race mentioned. The variety mixtures were affected less than the susceptible variety in pure stand. Decrease was significant mainly in mixtures with proportion of the susceptible variety less than 75 %. This mixture had higher disease severity of plants than mixtures with less proportion of the susceptible variety. The variety mixture with the least proportion (25 %) of the susceptible variety had the highest effect (95.65 %). There were no significant differences in the yield among variants.
