Al-sohaily 等研究丝黑穗病菌的生理分化指出,玉米丝黑穗病菌与高粱丝黑穗病菌应为2个不同的“变种”,分别命名为:Sphacelotheca reiliana var.Zeae 和 S.rei-(?)iana var.reiliana。国内的初步研究结果表明,来自不同地区的玉米丝黑穗病菌不存在明显的致病力差异。为探明高梁丝黑穗病菌的地区间差异性,深入研究病菌生理分化,为抗病育种提供依据,进行了此项试验,简报如下。 Al-sohaily other studies on the physiological differentiation of head smut pointed out that the head smut and sorghum head smut should be two different “variants”, respectively, named: Sphacelotheca reiliana var. Zeae and S. rei- ( ?) iana var.reiliana. The results of preliminary studies in China showed that there was no significant difference in virulence among pathogenicity of maize head smut from different regions. In order to find out the inter-regional differences of sorghum pathogen sorghum, in-depth study of physiological differentiation of pathogens, to provide the basis for disease-resistant breeding, this experiment, the briefing is as follows.
