title: Identification of QTLs for 14 Agronomically Important Traits inSetaria italicaBased on SNPs Generated from High-Throughput Sequencing.
abstract: Foxtail millet (Setaria italica) is an important crop possessing C4 photosynthesis capability. TheS. italicagenome wasde novosequenced in 2012, but the sequence lacked high-density genetic maps with agronomic and yield trait linkages. In the present study, we resequenced a foxtail millet population of 439 recombinant inbred lines (RILs) and developed high-resolution bin map and high-density SNP markers, which could provide an effective approach for gene identification. A total of 59 QTL for 14 agronomic traits in plants grown under long- and short-day photoperiods were identified. The phenotypic variation explained ranged from 4.9 to 43.94%. In addition, we suggested that there may be segregation distortion on chromosome 6 that is significantly distorted toward Zhang gu. The newly identified QTL will provide a platform for sequence-based research on theS. italicagenome, and for molecular marker-assisted breeding.
