Abstract: The bolting character showed by buding stage and bolting stage of 98 strains of Chinese cabbage had been observed in two years.The result showed that the time from sowing to buding of most strains is 101-112 d,the ratio is 73.8%.The ratio of materials that buding time was above 116 d was only 8.7%.The time from sowing to bolting of most strains is 105-116 d,the ratio is 75.1%.The ratio of strains that bolting time was above 120 d was only about 10.1%,and this date of Qingmaye type strains was more lower.The bolting time of DH lines of 3 groups that the bolting stage of their parents is different was observed.Result showed that if the bolting stage of their parents is near,the bolting time of their DH lines was concentrated.If that is far,the bolting time of their DH lines was scattered.There were generally DH lines which bolting time was earlier than the earlier parent,but there were few DH lines which bolting time was later than the later parent.

Key words: Chinese cabbage, Buding stage, Bolting stage, DH line, Genetic character
