Spring rapeseed hybrids of Chinese selection are characterized by high yield and good seed quality in the territory of the People's Republic of China. For more productive cultivation of any crop, research is needed to find the most effective varieties and hybrids of crops. Crop variety testing allows us to solve this problem. The purpose of this article is to conduct a comprehensive variety testing of various spring rapeseed hybrids to adapt to the conditions of Northern Kazakhstan and use the yield potential. To achieve this goal, it is planned to solve the following problems: determining field germination, plant safety, elements of the crop structure and seed yield of rapeseed hybrids. The subject of the study is spring rapeseed hybrids. The research was carried out according to the guidelines for variety testing of agricultural crops. The study includes economic and morphological indicators, as well as seed productivity. The results of the study helped to determine the most economically productive hybrid of spring rape between zoned hybrids in the North Kazakhstan region and hybrids of Chinese selection. The scope of application of the research results covers agriculture and the entire agro-industrial sector. The conclusions of the article provide recommendations for selecting optimal rapeseed hybrids for cultivation in the conditions of Northern Kazakhstan, which will help increase the yield level and production efficiency of this crop.
