In the comprehensive prevention and control system of wheat stripe rust, the identification of resistance to wheat stripe rust is a fundamental task, but many farmers have little understanding of it and may even wonder: this work sounds very professional, but what is its significance for actual wheat planting? In fact, the identification of wheat stripe rust resistance is closely related to the planting efficiency of farmers, which can reduce the risk of disease from the source.

The identification of wheat stripe rust resistance is mainly conducted through scientific experiments to evaluate the resistance ability of different wheat varieties to stripe rust. Based on the strength of resistance, varieties are classified into different levels such as high resistance, moderate resistance, susceptibility, and high susceptibility. The practical significance of this work mainly lies in two aspects: firstly, providing a basis for farmers to select crops. Before planting, farmers can refer to the resistance identification results published locally and choose high or medium resistant varieties suitable for local planting, fundamentally reducing the probability of stripe rust occurrence. For example, in areas with high incidence of stripe rust, selecting resistant varieties can effectively reduce the losses caused by the disease, and even achieve stable production without the need for medication in mild disease years. The second is to provide support for breeding work. Breeding experts screen wheat materials with resistance genes through resistance identification, and cultivate new varieties with characteristics such as resistance, high yield, and high quality, providing more reliable variety guarantee for agricultural production. For large-scale growers and planting cooperatives, understanding and utilizing the results of wheat stripe rust resistance identification can optimize variety layout, develop more scientific planting plans, reduce yield fluctuations caused by diseases, and improve planting stability and economic benefits.
