| 摘 要： | 玉米小斑病是由玉蜀黍双极蠕孢(Bipolarismaydis)引起玉米叶部发病的病害之一,该病害广泛分布在世界玉米产区,严重影响玉米生产。玉米小斑病菌存在明显生理分化现象,目前已证实在中国存在T、C、S和O共4个小种。由于近年来不育细胞质的感病玉米自交系在玉米育

| Abstract: | 21 strains of Bipolaris maydis were isolated from maize plants located at different region in Anhui Province.The physiological races were identified based on their pathogenic types on the Chinese differentials.And the sensitivities of 12 representive strains to diniconazole were also measured by the rate of increment of colony diameter.The results showed that four physiological races O,S,T and C existed in Anhui,and among them race O was dominant.EC50 values to the 12 strains for diniconazole were ranged fr... |
