In the conditions of Western Siberia under vari-ous options of processing of seeds fungicides and growth regulator Rostock revealed the grades of spring barley providing high-quality grain. The re-searches were conducted on experimental field of SAU of Northern Trans-Urals located in the north-ern forest-steppe of Tyumen Region. In the experi-ments the grades of spring barley were investigat-ed: filmy - Barkhatny (multirow), Biome (double-row) and hull-less - Nudum 95. It was established that preceding seeds processing with seeds dress-er Lamador, and also complex processing of seeds with seeds dresser and growth regulator Rostock promoted the improvement of indicators of techno-logical qualities in it. The greatest indicator of mass of 1000 grains was noted in grades Nudum 95 - 54.8 g and Biome - 54.3 g in option with complex processing of seeds, in grade Barkhatny high rate characterized option with seed dressing with Lamadory was 43.5 g. On average for years of re-searches of grade created grain with nature above basic norm on the barley made for Tyumen Region was 580 g/l. On grain protein content Nudum 95 (15.8- 16.2 %), and was distinguished from filmy grade Biome (12.7-14.1 %) the grade of hull-less barley. The greatest collecting protein from unit of area provided filmy double-row grade Biome 432 and was 470 kg/hectare. The correlation analysis of data showed that between the productivity of bar-ley, indicators of mass of 1000 grains and natures of grain there was average positive dependence (r = 0.48; r = 0.46 respectively), and between grain protein content and productivity of grades of barley inverse correlation relationship was established (r = - 0.56).
