Abstract

Grain weight （GW）, a quantitative trait determined by several genes, is one of three key wheat yield components and is sensitive to environmental variation. Researchers at home and abroad have done many studies on the genetic traits and molecular regulation mechanism of GW formation, and have made some research progress. How to make innovations to improve unit yield of wheat based on the existing research is an important work for the researchers. In this study, the latest research progresses on components, genetic traits, genetic mapping of QTLs （quantitative trait loci, QTLs）, candidate gene cloning and molecular regulation of GW in wheat were reviewed, and then the problems of existing research and the future research direction involved in our recent research were also sorted out and discussed. In order to get a comprehensive knowledge about the molecular mechanism on the production of GW, researchers should pay more attention to three key items. Firstly, the variation of hormone in the development of GW should be concerned and measured. Secondly, GWAS （genome-wide association study, GWAS） together with high throughput sequencing should be adopted to exploit SNP （single nucleotide polymorphism, SNP） markets conferring to some special agricultural trait. Finally, the candidate gene should be mapped based on SNP marker-assisted selection in the mapping population, and then the candidate genes should be cloned and their function in the regulatory network involved in the formation of GW should be covered. This work will provide a good reference for further research. ［Ch, 1 tab. 52 ref.］
