Abstract

OBJECTIVE:

To lay a foundation for the study on good variety selection of Isatis indigotica, comparison of plant traits and quality evaluation of Isatis germplasm resources from different production area was conducted.

METHOD:

Field cultivation and randomized block experiment were adopted to compare those plant traits of leaf, root, silique and seed of Isatis from different production area and the content of R,S-goitrin and polysaccharide in the root was determined.

RESULT:

Different cultivation forms of Isatis had significant difference from each other in leaf, root, silique and seed, content of R,S-goitrin and polysaccharide in the root were also different. R,S-goitrin content in Isatis of Chinese cabbage leaf type ( production area: Yunnan ) was comparative higher, 0.59% , while polysaccharide content in autotetraploid Isatis was comparative higher, 8.68%.

CONCLUSION:

According to the plant traits, Isatis were classified into three types: Chinese cabbage leaf type, cabbage leaf type and mustard leaf type, of which R,S-goitrin content in Chinese cabbage leaf type (production area: Yunnan) was comparative higher, while polysaccharide content in autotetraploid Isatis was comparative higher.
