玉米灰斑病研究进展

Research Progress of Maize Gray Leaf Spot

自1925年玉米灰斑病首次报道以来,至今该病菌已经在世界各地暴发,并导致产量大幅度的减少。农业科研人员从不同的方面对玉米灰斑病进行的研究,如病菌发生的条件、病菌传播的途径、对抗此病菌的方法等。同时,研究人员发现对抗灰斑病主要是改良品种、利用农药及改变农艺习惯。现阶段,对于利用分子辅助性育种来改良玉米品种的研究是一个热点,但主要还是集中在研究其QTL上。

Since gray leaf spot of maize was first reported in 1925,gray leaf spot had broken out all over the world,and lead to a drop in production greatly.This paper summarized the research from different aspects of agricultural scientific research personnel, such as gray leaf spot occurrence conditions ,gray leaf spot how to spread,what method was used to fight the disease.The researchers also found that against resistant mainly improved varieties ,the use of pesticides and the changing patterns of agronomy.At present ,for the use of molecular assistant breeding research is a hot topic for the modified maize varieties, but largely focused on the research on the QTL.
