Seed storability, measured by three indexes: germination rates after the 4-month (G4) and 6-month (G6) storage, and P50, the time required for a reduction of viability to 50% under natural storage; AOC: Antioxidant capability; Chr: Chromosome. Start: Physical position of a given bin based on the Rice Genome Annotation Project (Release 7). Bin size: size of the peak bin harboring a QTL. Add and PVE (%) indicate additive effect and phenotypic variance explained by a given QTL, respectively. The positive Add value represents the NIP alleles increased the effect.
