摘要： The brown planthopper (BPH) is an important pest of rice in Asia. One crucial measure to control BPH is to breed cultivars with durable resistance by identifying new BPH resistance genes and pyramiding major resistance genes. B5 is a rice line derived from wild rice Oryza officinalis. It is highly resistant to BPH biotypes 1 and 2 collected in China. The BPH resistance genes Bph14 and Bph15 have been identified in B5 and mapped onto rice chromosome 3 and chromosome 4,respectively. Marker-assisted selection (MAS) involves the use of molecular markers that are tightly linked to or cosegregating with the target genes, providing an effective means for the selection of BPH resistance genes in rice breeding programs. In this study, we used B5 as the donor of the BPH resistance gene and performed MAS for the genetic improvement of BPH resistance.
