Quantitative and qualitative protein composition peculiarities and amino-acid content variability in spring barley grains of different usage (for malting, feeding, and cereal consumption) depending upon the barley varietal characteristics and weather features are studied.
Five spring barley varieties bred by the institute were studied during growth with minimum tillage and application of mineral fertilizers for a planned yield of 2.5, 3.0, and 3.5 t/ha. High resistance to stress factors under sharply contrasting weather conditions and the best grain yield and quality were noted in highly plastic varieties.
As a result of many-year research, the methods of wheat breeding for resistance to pests and diseases have been developed. They are based on interspecific and remote crossings by the use of various types of step hybridization and multiple individual selection with account for determination of specifically assigned tasks. On that basis, the immune conception… (More)
