持续进行玉米品种抗病性研究，加强抗病育种工作，是保证玉米高产稳产的重要课题。陕西省由70年代开始系统进行此项研究，并不断完善和提高。针对玉米丝黑穗病、大小斑病、茎癌病、穗粒腐病等主要病害，研究总结出一套科学有效的鉴定技术。对数千份玉米自交系、测交种、杂交组合、农家种等进行鉴定，筛选出一批抗源和抗病品种。80年代以来，主要推广品种绝大多数化病性较好，但也存在一些需要改进的问题，提出了进一步加强玉米品种抗性研究的建议。
Continuing research on disease resistance of maize varieties and strengthening disease-resistant breeding work are important topics for ensuring high and stable yield of maize. Shaanxi Province began systematic research conducted by the 1970s and has been continuously improved and improved. Aiming at maize head smut, size spot disease, stem cancer disease and ear rot disease, the paper summed up a set of scientific and effective identification technology. Thousands of maize inbred lines, test crossbreds, cross combinations, farmer species were identified, screened a number of resistant and resistant varieties. Since the 1980s, most of the major varieties for promotion have good disease resistance, but there are still some problems that need to be improved, and some suggestions for further strengthening the research on the resistance of maize varieties are put forward.
