水稻(Oryza sativa)粒形性状包括粒长、粒宽、粒厚、粒重和长宽比等,是构成水稻产量的重要因素之一.因此,阐明水稻粒形遗传控制的机理,对提高水稻产量具有十分重要的意义.水稻粒形的遗传是多基因共同作用的数量性状遗传,相对于单一基因控制的性状,研究要相对复杂.该文综述了水稻粒形的遗传特点、QTL定位和基因克隆,并展望了粒形遗传的研究前景.
Progress in Genetic Research into Grain Shape in Rice
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.
