Abstract There are great differences in selenium accumulation ability in different species and varieties of crops．In order to define the differences in selenium accumulation ability between cabbage with different genotypes，this experiment selected cabbage varieties with strong selenium enrichment ability；took 18 main cabbage varieties from the major producing areas in the Middle-lower Reaches of the Yangtze River region as the test material；foliage sprayed 0，300，600 mL · （667 m2）-1 bio-organic selenium to compare the selenium enrichment capacity of cabbage with different genotypes．The results showed that comparing with the contrast of non-spraying selenium，there were differences between varieties in the yield per plant，selenium content of aboveground part，selenium accumulation amount of single plant，and selenium utilization efficiency．Foliage spraying 600 mL · （667 m2）-1 bio-organic selenium had the best effect．The average yield per plant of 18 cabbage varieties were increased by 9.01% than that of the contrast．Among them，‘Chunqiu 50’had the largest increasing range．The average selenium content in shoot and selenium accumulation per plant of 18 cabbage varieties were increased by 27.58 and 36.69 times，respectively，and selenium utilization efficiency was 68.06%．Clustering analysis indicated that among all tested cabbage varieties there were 7 high selenium accumulation varieties，7 medium selenium accumulation varieties，and 4 low selenium accumulation varieties．
