The disease-resistant study of maize chromosome segment introgress lines to common smut

Bo Yuan, Ximin Cao

The maize chromosome segment introgress lines play an importment role to minimize the losses caused by common smut. Ustilago maydis was injected into 8 maize chromosome segment introgress lines(CSILs). 8 CSILs have different chromosome segments of donor maize HB522 respectively. There are 4 kinds of varieties in 8 CSILs expressing highly resistance to common smut. Chr3-7’s grain yield is highest among other seven CSILs and two parents. chr3-7 is good SSILs for resistance to common smut study and resistance breeding
