Fine mapping of the major Soybean dwarf virus resistance gene Rsdv1 of the soybean cultivar 'Wilis'.

ABSTRACT: Soybean dwarf virus (SbDV), a Luteoviridae family member, causes dwarfing, yellowing and sterility of soybean (Glycine max), leading to one of the most serious problems in soybean production in northern Japan. Previous studies revealed that the Indonesian soybean cultivar 'Wilis' is resistant to SbDV and that the resistance can be introduced into Japanese cultivars. A major QTL for SbDV resistance has been reported between SSR markers Sat_217 and Satt211 on chromosome 5. In this study, we named this QTL Rsdv1 (resistance to SbDV) and developed near-isogenic lines incorporating Rsdv1 (Rsdv1-NILs) using Sat_217 and Satt211 markers. The Rsdv1-NILs were resistant to SbDV in greenhouse inoculation and field tests, indicating that Rsdv1 alone is sufficient for the resistance phenotype. We fine-m
