[Methods] From the 150 kinds of collected wild C. lacryma-jobi L. germplasm resources, 24 kinds of excellent resources were screened and detected. Morphological statistics were carried out, and the content of coixin in the four organ of roots, stems, leaves and seeds were measured, and the approved cultivar white husk Liugu of C. lacryma-jobi L. was taking as the control. [Results] Among the organs of the plant of C. lacryma-jobi L., the roots had the highest content of coixin, so the roots of C. lacryma-jobi L. can be used as the medicinal parts of C. lacryma-jobi L. [Conclusions] The wild C. lacryma-jobi L.Y229, Y164, Y166, Y83, and Y84 stains had excellent yield, and their root coixin content was significantly higher than that of the control variety, so they can be used for cultivation as excellent germplasm, so as to obtain new variety(line) of C. lacryma-jobi L.with higher content of coixin.展开更多
