关于水稻品种对白叶枯病抗性遗传的研究,国内外虽已有若干报道,但由于水稻白叶枯病菌的致病力有明显的地域性,抗病性的表现又实质上是水稻品种抗病基因与病菌致病基因相互作用的结果,不同抗病品种对不同菌系的抗性反应是不同的。为了充分了解所鉴定的抗源和主要抗病品种对本省致病力较强的白叶枯病菌抗性主效基因遗传方式和病斑扩展长度的数最遗传参数,以增强抗病育种的预见性,特进行本项研究。
Although there have been several reports at home and abroad on the inheritance of resistance to bacterial blight in rice varieties, the pathogenicity of the bacterial blight of the rice has obvious geographical characteristics, and the performance of disease resistance is essentially the resistance of rice varieties As a result of the interaction between the disease gene and the disease-causing gene, the resistance of different resistant varieties to different strains of bacteria is different. In order to fully understand the identification of the most resistant genes and the most resistant varieties of the province’s virulence of bacterial leaf blight resistance major gene genetic mode and the number of the most extended disease length genetic parameters in order to enhance the prediction of disease-resistant breeding Sex, especially for this study.
