abstract：MAIN CONCLUSION:Three novel QTLs for grain shape were genetically fine mapped, with two of which to a 250-kb target interval on rice chromosome 2 that contains fourteen candidate genes. Grain shape (grain length, width, and thickness) determines crop yield and grain quality. However, the trait is regulated by numerous ...
