玉米大斑病是玉米主要病害之一,对玉米生产危害极大。防治玉米大斑病需要多种措施,进行综合治理,而培育抗病杂交种则是其中最为经济有效的办法。过去,辽宁、河北、河南、陕西等省由于推广感病品种如维尔156、维尔42……等,曾引起大斑病的严重发生。近年来,我国部分地区又出现大斑病流行态势,已引起玉米育种工作者的广泛关注。与此同时,抗玉米大斑病遗传育种研究也取得许多新的进展。 Corn blight is one of the major diseases of maize, which is harmful to corn production. The prevention and treatment of maize leaf blight requires a variety of measures for comprehensive management, and breeding of disease-resistant hybrids is one of the most cost-effective way. In the past, Liaoning, Hebei, Henan, Shaanxi and other provinces as a result of the promotion of susceptible varieties such as Virgil 156, Virgil 42, etc., has caused the great spot disease. In recent years, the epidemic situation of spot blotch appeared again in some areas of our country, which has caused widespread concern of corn breeding workers. At the same time, many new advances have also been made in the research of genetic breeding against corn leaf spot.
