Progress on genetic regulation of the major aroma substances in grape

[ Objective ] Grape is an important cash crop in China , and aroma is the major component of the grape fruit quality. Grape aroma is complex and composed of a variety of compounds , including terpenes , volatile aliphatic compounds , aromatic compounds , pyrazines , and sulfur-containing compounds. It is af- fected by multiple factors , where genetic regulation is the main factor affecting its aroma. Therefore , ana- lyzing genetic regulation of grape aroma production provides a basis for achieving breeding goals. [ Reviews ] This paper reviewed the methods of grape aroma measurement , followed by summarizing and analyzing the genetic regulation and QTL mapping of grape aroma traits. [ Prospect ] This paper laid a the- oretical foundation for analyzing genetic regulation of grape aroma and provided a reference for grape aroma trait- directed breeding.
