Abstract: Research on grape genetic linkage maps is a crucial step in elucidating the relationships between important grape traits and molecular markers, and is also the basis for systematic studies of the genome and molecular marker-assisted breeding. At present, substantial progress has been made in the research on grape genetic linkage maps both domestically and internationally,such as QTL mapping for important traits including grape phenological stages,growth traits,berry firmness,berry size,berry skin color,berry aroma,seed number,phylloxera resistance,and downy mildew resistance. This paper reviews the construction of grape genetic linkage maps and QTL mapping for major agronomic traits and related studies over the past 20 years both domestically and internationally. It also analyzes the existing problems in grape genetic linkage map research and discusses future research directions. The aim is to provide a reference for identifying genes associated with important agronomic traits and for conducting molecular marker-assisted breeding of grape.

Key words: Grape, Genetic linkage map, QTL mapping, Molecular marker
