T/XZBX 0078-2025 Technical Specifications for the Breeding and Cultivation of Stress-Resistant Crop Varieties in Northern Fields

Scope

The northern region is an important grain production base in China, with extensive planting areas and major field crops including wheat, corn, soybean, potato, and mixed grains. However, the region is characterized by complex and changeable climate conditions, with frequent occurrences of drought, low temperatures, salinization, and pests and diseases, which seriously affect the stable production of crops and farmers' income. Improving the resilience of field crops is not only an inevitable requirement for ensuring food security but also a core task for promoting sustainable agricultural development. In recent years, with intensifying climate change and declining arable land quality, the resilience of field crops in the north has become increasingly prominent. Low temperatures and late frosts in spring easily lead to frost damage during seedling stage, while drought and high temperatures in summer often cause yield losses. Meanwhile, land issues such as salinization and desertification further increase cultivation difficulties. At the same time, the occurrence of pests and diseases has become more frequent and regionalized, exacerbating the uncertainty of agricultural production. Against this backdrop, the selection and rational distribution of resilient varieties have become particularly important. Research on resilience breeding and cultivation techniques at home and abroad has been continuously deepened. The application of advanced methods such as molecular breeding, gene editing, and precision breeding has provided new pathways for variety improvement. At the same time, the promotion of green and efficient cultivation measures, water-saving and drought-resistant irrigation technologies, and methods of efficient nutrient utilization have also provided important support for stable and increased production of crops under adverse conditions. Based on the summary of existing research and practical experience, and in combination with the actual needs of field crop
