Identification and Analysis of Resistance to Northern Corn Leaf Blight in Maize Germplasm Resources.

ABSTRACT: Northern corn leaf blight (NCLB), caused by the fungus Exserohilum turcicum, is one of the most significant foliar diseases in maize worldwide, with its severity being highly influenced by environmental conditions. An effective strategy used to control NCLB involves screening diverse maize germplasm for resistant sources through multi-environment inoculation assays, ultimately aiming to develop resistant varieties. This study systematically evaluated 711 maize germplasm accessions with rich genetic diversity. The evaluation was conducted under four location-year environment combinations (Shangluo, Shaanxi Province, China in 2014-2015 and Xinzhou, Shanxi Province, China in 2021-2022) using artificial inoculation with physiological race 123N (or races 1, 2, 3, N). The results showed t
