2006～2009年间吉林省通过审定的玉米品种有203个,对审定品种的抗性鉴定结果进行分析,比较吉林省审定品种的抗性水平变化。结果表明,吉林省通过审定的品种在抗性方面大多属于综合中抗水平,在审定品种对所有病虫害的抗性鉴定结果中,对玉米大斑病、玉米茎腐病和玉米螟的抗性审定严格控制,对吉林省区域性发生且危害小的玉米弯孢菌叶斑病和能够通过种衣剂防控的玉米丝黑穗病要求相对降低。抗源筛选和分子辅助育种是现代抗逆育种的基础条件,耐密抗倒伏成为现代育种的重要指标。
From 2006 to 2009, 203 maize varieties that were validated in Jilin Province were analyzed, and the results of resistance identification of the tested varieties were analyzed. The changes of the resistance level of the tested varieties in Jilin Province were compared. The results showed that most of the tested cultivars in Jilin Province belonged to the integrated resistance level in the resistance test. Among the resistance test results of the tested cultivars to all diseases and insect pests, the resistance to corn leaf spot, maize stalk rot and corn borer Strict control on the regional occurrence in Jilin Province and less harmful to Curvularia leaf spot and can be controlled by seed coating maize smut requirements are relatively lower. Resistance screening and molecular-assisted breeding are the basic conditions for modern anti-retrograde breeding, and tolerance to lodging and resistance has become an important indicator of modern breeding.
