摘要

玉米粒的特点是以易于消化的形式存在生长和发育所需的所有营养物质、宏量和微量元素。考虑到土壤和种植气候区的差异,育种过程旨在建立不同成熟群体的杂交种。本研究旨在评估不同成熟度群体的玉米杂交种的一系列经济和生物学特征,包括生产力、高产稳定性,以及在适合机械化收割的生产条件下进一步种植。研究方法包括信息法、理论分析法、综合法、类比法、比较法和概括法;研究鉴定和测量。在研究过程中,考虑到杂交玉米种植的技术、生产和经济条件的独特性,进行了系统分析。研究结果表明,为了成功调节玉米杂交种的生产力并提高其质量,有必要选择适合特定土壤和气候区的作物,考虑到对种子的生物要求,并开发有效的农业技术手段,以适应不同生长发育阶段的过程。通过育种形成的玉米杂交种的种子营养含量较高:中早熟玉米的粗蛋白质含量为9.2-9.9%,粗脂肪含量为4.2-4.4%,无氮提取物含量为82.5-83.3%,淀粉含量为71.4-73.7%;中后期组的粗蛋白质含量在9.8-10.4%之间,粗脂肪含量在4.1-4.6%之间,BER含量在80.6-82.2%之间,淀粉含量在70.2-74.1%之间;中熟组分别为296-351cm、318-382g、0.455

Comparative analysis of the main economic and biological parameters of maize hybrids that determine their productivity
Corn kernels are characterised by the presence of all the nutrients, macro- and microelements necessary for growth and development in an easily digestible form. Considering the differentiation of soil and climatic zones of cultivation, the breeding process is designed to establish hybrids of different maturity groups. The research purposes to evaluate maize hybrids of different maturity groups for a set of economic and biological traits of productivity, high-yield stability, and further cultivation in production conditions suitable for mechanised harvesting. Methods used in the research include informational, theoretical analysis, synthesis, analogy, comparison and generalisation; research identification, and measurement. During the research, a systematic analysis was applied, considering the uniqueness of technical, productive, and economic conditions for growing hybrid corn. The research results demonstrate that to achieve successful regulation of maize hybrids productivity and improve their quality, it is necessary to select for suitability for specific soils and climatic zones, considering the biological requirements for seeds and developing effective agrotechnical means designed for processes occurring at different stages of growth and development. The seeds of corn hybrids, formed by breeding, were determined by a high nutrient content: In mid-early corn, the content of crude protein was 9.2-9.9%, crude fat – 4.2-4.4%, BER (nitrogen-free extractives) – 82.5-83.3%, starch – 71.4-73.7%; in the medium-late group, the content of crude protein ranged from 9.8-10.4%, crude fat from 4.1-4.6%, BER from 80.6-82.2%, and starch from 70.2-74.1%. The medium-early group of hybrids obtained the optimal height of 245-276 cm, the weight of 1000 seeds – 308-344 g, the ratio of node height to plant height – 0.445; the medium-ripening group respectively 296-351 cm, 318-382 g, 0.455
