Abstract

As a result,comprehensive assessmentwas conducted and oat gradesof differentmaturity groups, forminga stableyield,structural elements, as havingagronomicresistance toabioticandbiotic stresses were identified. Oat grades of domestic and foreign selection were studied, allowing to evaluateand identify theirgenetic potentialand to determine thebest adaptedvarietiesfor cultivation inarid steppesof northern Kazakhstan. The parameters of the most important economically valuable attributes and properties were revealed. Grades with optimal parameters specified attributes were identified and most to the local climate were selected. Among the best grades of oats a working collection for later use in the creation new highly adopted, competitive sortsof oats will be created.
