The paper explores breeding and seed production in Northeastern Kazakhstan, specifically focusing on the introduction of new wheat, oats, and Sudangrass varieties by LLP "Pavlodar Agricultural Experimental Station".The research, conducted across 16 experimental sites in various districts of Akmola, North Kazakhstan, Karaganda, Pavlodar, and Kostanay regions, used standard field and laboratory methods to enhance agricultural yields and bolster food security in the region.The varieties of spring wheat (Anel-16 and Ertis 7), oats (Ertis samaly and Mirny), and Sudangrass (Dostyk 15) were investigated.The yield of crops, the weight of 1000 seeds, the protein and gluten content in wheat and oat grains, and the yield of normalised dry matter in the harvest of Sudangrass are determined.Variance and correlation analysis are used for statistical processing.The influence of weather conditions (average daily air temperature, precipitation amount, and Selyaninov hydrothermal coefficient for the growing season 2017-2019) on crop development and protein content in wheat and oat grains, and the herbage of Sudangrass have been established.The most favourable areas of cultivation of the varieties of agricultural crops are indicated.
