This diploma thesis Comparison of yield capacity of spring wheat varieties deals with small-scale experiments of three varieties (Astrid, Epos, Tercie) in two vegetation periods. Repetition variations were established in 2015 and 2016 on the school grounds of the Agricultural Faculty of the University of South Bohemia in České Budějovice. During two growing seasons the production of yield elements (the number of plants and the number of fertile crops - ears) was monitored for all varieties and after harvest other yield elements were evaluated the number of grains in the ear and weight of a thousand grains. Actual revenue was determined. Grain analysis determined the bulk density as a quality indicator. In the results and discussion the individual yield elements are described and statistically evaluated. The number of plants was better in 2015 regarding soil density characteristics. The number of fertile offsprings was the highest in the case of Astrid variety in the first production year (642). The number of grains in the ear was very variable for all observed varieties, both production years 2015 and 2016 (from 15 grains in the ear to 68 grains in the ear). Total actual yield was higher in 2015 than in 2016 (by 1.1 t.ha-1). Each spring wheat is characterized by its shorter growing season, during which it must optimally produce the highest yield possible and therefore needs adequate responsible care.
