Issue №: 2 (41)
This issue of the journal is dedicated to current issues in improving technological methods for crop cultivation. Significant attention is given to the specifics of growing vegetable, grain and leguminous crops, which play a vital role in ensuring the state's food security. The scientific publications present the results of experimental research on the production of organic leguminous products, the importance of adaptive breeding to increase the resilience of agrocenoses, plant protection against harmful objects and the application of fertilizers to increase crop yields. Certain papers are devoted to the implementation of innovative methods for stimulating the seed productivity of forest seed plantations.

Corn is one of the world’s leading agricultural crops, playing a strategic role in ensuring food and energy security. In global productionled by the United States, China, and Brazil−specialization and the development of hybrids with improved biochemical composition are becoming increasingly important. However, traditional corn grain has a significant drawback−low biological value of its protein. The majority of endosperm proteins consist of zeins, which contain virtually no essential amino acids such as lysine and tryptophan. Solving this problem became possible thanks to the discovery of a gene (opaque-2) capable of altering the ratio of protein fractions in the grain, significantly increasing the lysine content (to 4.05–5.0% of total protein compared to 2.0%–2.5% in conventional corn). The use of high-lysine corn allows for the balancing of feed in terms of amino acid composition, which is important for feeding pigs and poultry. This paper presents the results of a comprehensive evaluation of breeding material from self-pollinating maize lines carrying the opaque-2 gene of various genetic origins (the BL, TVA, and IL series) from the collection of the National Center for Plant Genetic Resources of Ukraine. The research aims to identify economically valuable traits and biochemical indicators of grain to improve the amino acid composition of feed without compromising the physical characteristics of the endosperm. It was found that the lines under study exhibit significant variability in terms of seed yield and biochemical composition. The highest grain yield potential was found in the BL series lines (specifically BL 35−92 g of grain per plant), while the TVA and IL series lines are characterized by a higher protein concentration (up to 12.5% in IL 80). The lysine content in all samples confirmed their status as high-lysine varieties (3.9–4.5% in protein). It was found that the TVA series lines are promising sources for breeding for increased starch content (over 68%) while simultaneously reducing the amylose fraction (23.8–24.6%), making them valuable material for breeding for carbohydrate complex quality. The selected lines with high lysine content and specific starch composition allow for the creation of competitive “High-Lysine” hybrids; the obtained data are of practical significance for balancing animal feed rations and creating new high-quality corn hybrids.
