Abstract Recently，association analysis has been widely employed to investigate quantitative traits in plant genetics and breeding．It is an approach to identify the relationship of molecular markers or candidate genes with traits in a given population based on linkage disequilibrium（LD）．This approach is also a new idea for the study of quantitative traits in vegetable crops．In this paper，the basic statistic principles，strategies，and current successful applications of association analysis in vegetable crops were reviewed．The potential application of association analysis in vegetable crops molecular breeding were also discussed．
