Abstract: Grain shape, including grain length, width, thickness, and weight and aspect ratio, is an important factor for rice production. Therefore, genetic analysis of grain shape is of great significance for increasing rice yield. Grain shape is a quantitative trait controlled by multiple genes. As compared with research into traits controlled by a single gene, that for genes controlled by multiple genes, such as grain shape, is complicated. We summarize recent progress in genetic research into grain shape in rice and future prospects.
