【摘要】 选用专化抗性品种人为地单一扩大其种植面积以防治小麦条锈病,将迅速导致品种的专化抗性失效。在小麦群体中配置一定比例不同抗性的品种能显著地降低初次侵染原的有效率,同时也减少了再次侵染原的数量从而减缓了病害的流行速度。将专化抗性和群体延缓抗性结合起来以抑制条锈病的流行,无疑地是防治气传性流行病害的一个重要手段。更多还原

【Abstract】 A special resistance cultivar grown and spread solely in a certain area to control wheat stripe rust will cause the original resistance invalidation rapidly. To manage several cultivars possessing various resistance in wheat population or in a cetrain area is available for decrease both the infection cffcieecy of original pathogen and the number of reinfection pathogen so apparently that the disease can be alleviated. Using the combination of special resistance and slow resistance in population to control the stripe rust is a progress in defence against attack of airborn epidemic disease.更多还原
