Abstract:

Rice (Oryza sativa L.) grain shape includes a series of agronomic traits such as grain length, grain width and length to width ratio, which is one of the most important factors affecting the quality and yield of rice. With the development of functional genomics and molecular marker technology, more and more grain shape genes are gradually located and cloned. This paper mainly summarizes the genes that have been cloned in relation to rice grain shape: grain length gene: GS3, GL7, GL3.3, etc.; grain width gene: GW2, GW5, GS5, etc.; length to width ratio gene: GW7, TGW3, GS2, etc., and the relationship among these genes and their applications in production. At the same time, the problems of rice grain shape gene in molecular plant breeding are pointed out and corresponding suggestions are put forward.
