摘　　要：利用自然诱发结合人工接种的鉴定方法,对2020、2021和2023年2468份玉米品种进行南方锈病田间抗性鉴定,对2023年表现中抗以上的439个参试品种进行RppC和RppK抗性基因检测。结果表明,高抗和抗病品种的比例从0.59%、6.46%(2020年)提高至2.99%、7.2%(2021年)和3.33%、13.13%(2023年);感病品种占比较高,3年占比分别为53.74%、38.99%和29.5%。439个参试品种中的221份携带RppC抗性基因,占50.34%;209份携带RppK抗性基因,占47.61%;有75份同时携带RppC和RppK基因,占17.08%;有84份未检测到RppC和RppK抗性基因,推测可能携带其他抗性基因。综上,黄淮海夏玉米区新选育的玉米品种对南方锈病的抗性水平在逐步提高,抗性品种中以携带RppC抗性基因为主,育种上应加强RppK抗性基因的转移利用。Two thousand four hundred six-eight maize varieties in 2020,2021 and 2023 were identified for field resistance to southern rust by natural induction and artificial inoculation.Additionally,resistance genes RppC and RppK were tested on 439 varieties(above moderately resistance)in 2023.The results showed that the proportion of highly resistant(HR)and resistan(R)varieties increased from 0.59%and 6.46%(2020)to 2.99%,7.2%(2021),and 3.33%,13.13%(2023).The proportion of susceptible(S)varieties is relatively high,accounting for 53.74%,38.99%,and 29.5%in three years,respectively.221 out of 439 varieties carried RppC resistance genes,accounting for 50.34%;209 varieties carried RppK resistance genes,accounting for 47.61%.Among them,75 varieties carried both RppC and RppK genes,accounting for 17.08%;84 varieties did not detect RppC and RppK genes,suggesting that they may carry other resistance genes.In summary,the resistance level of newly bred maize varieties to southern rust in the summer maize area of Huang-Huai-Hai is gradually improving.The primary resistance gene in these varieties is RppC and the utilization of RppK resistance genes should be strengthened in breeding.
