通过国内玉米骨干自交系和广泛种植的玉米品种的筛选 ,确认用自交系京135,78599 -1,Mo17,吉477,C8605,E28,478和黄早4作为玉米弯孢菌叶斑病菌生理分化的鉴别寄主 ,将采自中国主要玉米产区的玉米弯孢菌叶斑病菌划分成不同的若干生理分化类型。玉米弯孢菌叶斑病菌生理分化苗期温室和大棚鉴定与成株期鉴定结果一致 ,是该病菌生理分化适宜的鉴定方法 ,鉴别寄主生长条件如温、湿度和氮、磷营养也会对病菌生理分化鉴定产生影响
Through inbred lines of maize and maize varieties widely planted in China, the inbred lines Jing 135,78599 -1, Mo17, Ji 477, C8605, E28,478 and Huangzao 4 were identified as the main species of Curvularia lunata, Physiologically differentiated differential hosts will be divided into a number of different physiologically differentiated types of Curvularia lunata from the main maize producing areas in China. Physiological differentiation of Curvularia lunata showed that the identification of greenhouse and greenhouse in greenhouse and greenhouse at the seedling stage was consistent with the identification of the adult plant. It was an appropriate method to identify the physiological differentiation of the pathogen. Identification of host growth conditions such as temperature, humidity, Physiological differentiation have an impact
