With rising living standards, there is an increasing demand for high-quality rice. Rice quality mainly defined by milling quality, appearance cooking and eating nutrition quality. Among them, chalkiness a key trait which adversely affects head rice yield, commercial value. Therefore, undesirable, reducing major goal in improvement. However, complex jointly influenced genetic environmental factors, making its study precision improvement huge challenge. the rapid development of molecular techniques, much knowledge has been gained about genes networks involved formation. The present review describes factors affecting summarizes quantitative loci (QTL) associated with chalkiness. More than 150 related to formation have reported. functions regulating chalkiness, primarily those starch synthesis, storage protein transcription regulation, organelle development, grain shape high-temperature response, are described. Finally, we identify challenges suggest potential strategies. Thus, offers insight into dynamics provides strong basis future breeding varieties.
