美国锈病专家威·廉·雷格林教授,对作物的一般抗病性,给予这样的定义:“任何遗传因子能使寄主减轻损害,而不知道是由于专化性造成的抗性,称为一般抗病性”。近年以来,国外许多学者证明,作物对病原物的一般抗性,确是减轻病害损失的一种可能方法。很多国家的植物病理和育种工作者密切合作,根据经验来选择一般抗病性并应用于作物抗病育种。水稻、马铃薯、果树等育种实践中,已有成功的实例报道。一般抗性对于小麦锈菌这样一类变异性和专 American rust specialist Professor William Lowing, on the general resistance of crops, gives the definition: “Any genetic factor can make the host mitigate the damage, but do not know due to the resistance caused by specialization, known as the general Disease resistance. ” In recent years, many foreign scholars have proved that the general resistance of crops to pathogens is indeed a possible way to reduce the loss of diseases. In many countries, plant pathology and breeding workers work closely with each other to select the general disease resistance based on experience and to apply it to crop disease-resistant breeding. Rice, potatoes, fruit trees and other breeding practices, there have been successful examples reported. General resistance is a type of variability and specificity for wheat rust
