多年来防治稻瘟病的实践证明,开展以抗病品种为基础的综合防治是最经济和有效的.要育成一个生产上能利用的抗病品种,就必须寻找理想的抗源并掌握所用抗源与不同生理小种之间的相互关系,以期确定其抗源的使用价值,使之为抗病育种工作服务.本文从病原菌——寄主相互关系的角度出发,结合福建省稻瘟病菌生理小种的辅助鉴别品种筛选工作,开展了63个水稻品种的抗性研究工作.
The practice of prevention and control of rice blast over many years has proved that it is the most economical and effective to carry out the comprehensive prevention and control based on resistant varieties. To cultivate a disease-resistant variety that can be used in production, we must find the ideal source of resistance and master the source of resistance And physiological races in order to determine the value of its use of resistance to disease resistance breeding services.This paper from the pathogen - host the relationship between the perspective of pathogenic bacteria in Fujian Province, the combination of physiological races Of assisted identification of varieties of screening work carried out 63 rice varieties of resistance research.
