JX06-1-6 is a newly screened Bupleurum strains line by strains from wild Bupleurum chinense population. In 2010, the average yield of JX06-1-6 is 1 338.0 kg/hm2, which is 24.6% higher than that of the check Hongchaihu in the multi point region text, ranking the 6 varieties of first. The result shows that the thick taproot, hard skin, light brown, with few lateral roots, the main stem shaped bend significantly, which root length is about 18.80 cm, diameter is 9.27 mm, root weight is 2.13 g, the average plant height is 83 cm, with 3 to 4 upper stem branches, from 13.60 internodes, the diameter is 4.72 mm. The fruit is long elliptic, the long is 2.50 ~ 3.70 cm, 1 000-grain weight is 0.9 g. The disease rate is about 5% in the field, strong anti clubroot of Chinese cabbage, excellent quality, moisture content is 5.80%, the total ash is 4.60%, acid insoluble ash content is 1.4%, extract matter is 22.80%, the content of saikosaponin a (C42H68O13) and saikosaponin d (C42H68O13) is 0.92%.
