以抗感反应显著不同的水稻代表品种，研究了不同接种调查方法在抗纹枯病遗传研究中的适用性。结果表明，带菌短牙签嵌入接种，植株间始病迅速且整齐一致，感病品种发病适度，不同品种间抗感差异最为明显。病情调查的适宜时间在抽穗后３０ｄ左右（视品种灌浆期长短而异）或发病初期，而在明显拔节到抽穗阶段，品种内由于茎杆伸长时间的差异，病斑发展的差异增大，致使品种间抗感差异不易被识别。并且还讨论了不同病情调查项目的适用性。
The representative rice varieties with significantly different anti-allergic responses were studied. The applicability of different inoculation methods to the genetic studies on sheath blight was studied. The results showed that inoculation with short toothpicks carrying inbreeding occurred rapidly and neatly among plants, the susceptible varieties were moderately affected, and the most obvious difference was the resistance between different varieties. The appropriate time of disease investigation about 30 days after heading (depending on the length of the grain filling period) or early onset, and in the obvious jointing to heading stage, within the varieties due to differences in stem elongation, lesion development increased, Resistant to the differences between the varieties is not easy to identify differences. And also discussed the applicability of different disease investigation items.
