About
Lars von Post is a leading figure in plant molecular breeding, with a primary focus on developing genetic resistance in winter barley against devastating viral pathogens. His key research areas include marker-assisted selection, disease resistance genetics, and the application of molecular tools to accelerate crop improvement. Von Post’s most significant contribution came from his seminal 1998 work on the *ym4* gene, which confers resistance to Barley Mild Mosaic Virus (BaMMV) and Barley Yellow Mosaic Virus (BaYMV). In this highly cited study (24 citations), he pioneered a large-scale molecular breeding procedure using a codominant STS marker derived from an RFLP marker, enabling breeders to efficiently fix resistance in early generations. This breakthrough dramatically reduced the time and cost of developing resistant barley varieties, directly benefiting European agriculture where these soil-borne viruses cause substantial yield losses. Von Post’s work exemplifies the practical translation of genomic tools into applied breeding programs, and his marker-assisted selection strategy for *ym4* remains a cornerstone methodology in barley resistance breeding. His research continues to influence modern approaches to durable virus resistance in small-grain cereals.
