Abstract：Brassica oleracea vegetables，a group of leafy crops encompassing cabbage，cauliflower， broccoli，kohlrabi，brusselssprout，and kale，face persistent challnges in productionand breeding，including premature bolting and asynchronous flowering between two parents.Improving bolting resistance by molecular design breeding strategies holds significant promise.However，the genetic complexity underlying flowering regulation in B .oleracea is compounded by the diverse flowering mechanisms across subspecies and fragmented knowledge of associated regulatory genes.This review concludes optimal environmental conditions for flowering of B .oleracea vegetables and summarizes genes and variants for flowering pathways which are mainly involved in gibberelin pathway，vernalization，and photoperiodic responseson the basisoffive main flowerregulation pathways in higher plants.The prospect of the folow-upresearchon theregulation of boltingand flowering of cabbage vegetables is also suggested.A conceptual gene interaction network that integrates key regulators of bolting and flowering of B .oleracea vegetables is proposed， providing a valuable reference for improving bolting resistance of B .oleracea vegetables.
