Improvement of Resistance to Rice Stripe Virus in Wuyunjing 8 via Molecular Marker-Assisted Selection
A molecular marker-assisted selection (MAS) strategy was used to improve resistance to Rice stripe virus (RSV) in rice (Oryza sativa L. subsp. japonica cv. Wuyunjing 8). Rice variety “Aoikaze” with resistance to RSV was used as the donor. Sequence-tagged site (STS) markers STS11-31, STS11-7, STS11-19, and STS11-43 anchoring the resistance loci were used for MAS in the backcross progenies. In 2008, 70 lines of BC3F5 and 115 lines of BC4F4 population were obtained with stable agronomic traits after MAS assay. Further evaluation of agronomic traits, yield, grain quality, and resistance to RSV were carried out in these backcross progenies, and 10 BC4F5 lines and 2 BC3F6 lines showed similar phenotypes to Wuyunjing 8. The 12 lines were finally selected for the improved resistance to RSV and the high-yield and elite-quality of Wuyunjing 8.
