水稻粒形的遗传研究进展

Research progress of grain shape genetics in rice

摘要: 粒形不仅是影响水稻产量的要素，还与稻米的外观品质密切相关，是决定稻米品质的重要因素。随着现代遗传学和基因组学相关理论和技术的发展，人们对粒形的遗传研究日趋深入，目前已有数十个控制水稻粒形的基因被克隆。本文概述了水稻粒形遗传研究主要进展，同时也指出了水稻粒形遗传研究中存在的主要问题，分析了粒形遗传研究的前景。

Abstract: Grain shape controls rice yield. Meanwhile, grain shape is related to rice appearance quality, and an important element determing rice quality. With the developments of modern genetics and genomics related theories and technologies, the genetic researches on grain shape are gradually deepened. Now dozens of QTLs controlling grain shape are cloned. This review summarizes the main progresses of genetic researches on grain shape, points out the major problems and analyzes the prospects.
