Diseases have been major biological adversity affecting maize production. Breeding disease resistant varieties is the most economical, and effective for maize disease prevention. This study analyzed the disease resistance traits of ordinary maize varieties in Jilin Province from 2012 to 2021, including northern maize leaf blight, head smut, stalk rot, maize borer, Curvularia leaf spot, gray leaf spot and ear rot. The results showed that stalk rot, maize borer, ear rot, gray leaf spot, head smut, Curvularia leaf spot, and northern maize leaf blight were ranked from high to low in terms of resistance(R) with medium resistance(MR) or above. The varieties with extremely early maturity, early maturity and early-medium maturity, medium maturity, late-medium maturity and late maturity groups with MR or above accounted for 62.1%, 57.4%,49.3%,7.8%,5.4% and 0.5% of the total. The disease-resistant level of maize varieties was relatively high in Extremely early maturity, Early maturity and Early-medium maturity groups. But the total disease resistance level of maize main diseases and pests was very poor. The general change tendency of disease resistance of maize varieties showed downward trend. The majority of breeders should attach great importance to the change tendency. This study clarified the main disease resistance level of maize test varieties in recent year in Jilin Province, and provides a reference for future variety breeding, validation, and promotion to help China's maize seed industry become greener.
