Taking 100 advanced inbred lines of Chinese cabbage〔Brassica campestris L. ssp. pekinensis （Lour）Olsson〕as experimental material，this paper studied the effects of plumule- and seeding-vernalization on bolting and flowering times．The results showed that both the bolting and flowering times of plumule-vernalized material were advanced 15.0 days and 11.5 days，respectively，than that of seedling-vernalized material．Besides，only seeding-vernalization without plumule-vernalization，the inbred line of‘Chunquanda’could not promote bolting and flowering，while seeding-vernalization could make it bolting．This phenomenon might due to the different controlling molecular mechanism of these 2 vernalization modes．Chinese cabbage varieties
with different winter natures had consistent changing trend of bolting and flowering under these 2 vernalization treatments，indicating that the effects of these 2 vernalization modes on different Chinese cabbage varieties had versatility and consistency．
