Genomic selection for durable stem rust resistance in wheat

摘要: Inheritance of stem rust (caused by Puccinia graminis f. sp. tritici) resistance in wheat can be either qualitative or quantitative. While quantitative disease is believed to more durable, it difficult evaluate if expressed only mature plants, i.e. adult plant (APR). Marker-assisted selection (MAS) methods for APR would useful; however, the multigenic nature impedes use MAS efforts that aim pyramid a few target genes. A promising alternative genomic (GS), which utilizes genome-wide marker coverage predict genotypic values traits. In turn, GS reduce cycle length breeding program traits like could take several seasons generate reliable phenotypes. this paper, we describe process crop improvement, both specifically and general. We also propose GS–based scheme that, when compared current schemes, time up twofold facilitates pyramiding major genes with Thus, an important tool achieving Borlaug Global Rust Initiative’s (BGRI) goal developing durable wheat.
