小斑病是我省玉米生产上的主要病害,继1966、1967年连续大发生后,小斑病在我省每年都不同程度发生为害。一般中等发生年,感病品种减产两成左右。实践证明,采用抗病品种为主的综合防治措施是经济有效的。为了加快抗病育种的步伐,我们对有关玉米品种对小斑病的抗病性鉴定技术方法进行了试验研究。 Smaller spot is the main disease in corn production in our province. Following the successive occurrences of 1966 and 1967, Slityphomycosis occurs in varying degrees every year in our province. Generally occurs in mid-year, susceptible varieties cut about two percent. Practice has proved that the use of disease-resistant varieties of integrated control measures are cost-effective. In order to speed up the breeding of disease-resistant breeding, we conducted a pilot study on the identification methods of disease resistance against small spot disease in maize varieties.
