本研究以明了品种对条纹叶枯病耐病性的要点为目的,探讨田间耐病性的鉴定方法,分日本水稻、陆稻和其他外国稻的田间耐病性,解释其耐病性和媒介昆虫灰稻虱的关系,另外,进行品种对病原病毒反应的生理、生态实验,进而进行了解耐病性品种育成可能性的试验。 1、鉴定品种的田间耐病性,因排列方式不同而有变化。在鉴定品种间加入抗病性弱的品 In this study, the purpose of this study was to understand the key points of the disease resistance of stripe disease in wheat cultivars. The methods of identifying the disease resistance in field, the field tolerance of Japanese rice, Upland rice and other foreign rice, In addition, the variety of pathogenic virus response to physiological and ecological experiments, and then to understand the possibility of breeding disease-resistant varieties of the test. 1, Identification of the field of disease resistance, due to the arrangement of different ways. In the identification of varieties to join the weak disease-resistant products
