Hayes等（1925）在麦类作物抗锈性研究中发现了慢锈性。随后有人发现小麦条锈病免疫品种和高度感病品种（染病后产抱旺盛品种）之间存在着一系列中间类型，其中有些与慢锈性有关，为此开展了多方面的研究工作。1987年，孙月海等发现小麦慢锈品种在组织细胞水平上时条锈菌小种的 Hayes et al. (1925) found slow rust in studies on the rust resistance of wheat crops. Subsequently, it was found that there was a series of intermediate types between wheat stripe rust immunospecies and highly susceptible varieties (experiencing strong blooms), and some of them were related to slow rust. Various research efforts were carried out for this purpose. In 1987, Sun Yuehai and other found that the slow-rust wheat varieties at the level of tissue cells races of races
