Abstract: The soil culture experiments were performed to study the difference of Cd uptake and accumulation among 20 Hebei major Chinese cabbages cultivars. The obvious difference was observed in Cd uptake and Cd accumulation among all the species. Maximum difference of shoot Cd concentration and Cd uptake among all Chinese cabbages were 3-4 folds under same soil Cd concentration(1.0, 5.0 mg/kg). According to maximum allowable levels of Cd in national vegetables standards GB15201-94, the Chinese cabbage species Xinbeijing 3hao,Beijing xaioza 60,Taikong 3hao and Fengkang 78 accorded with the vegetable food security when the soil Cd concentration reached 1.0 mg/kg. According to GB2762-2005, under the maximum allowable levels of the leafy vegetables Cd standard, the Chinese cabbage species Xinbeijing 3hao,Beijing xaioza 60 and Fengkang 78 still accorded with the vegetable food security when the soil Cd concentration reached 5.0 mg/kg,. The enrichment factor of the same cabbage varieties is relatively stable. It can be used as screening an important indicator of cabbage varieties on Cd accumulation capacity .
