Abstract

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

Author(s): 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
