In order to screen out coix seed germplasm resources suitable for cultivation in Shanxi, 23 coix seed germplasm resources from different habitats in China were comprehensively analyzed for agronomic traits such as plant height, granulation layer, number of main stem nodes, branch node positions, and effective tiller number. Evaluation, in order to provide theoretical reference for the creation of new germplasm of Coix and the breeding of excellent new varieties. The experiment adopted a completely randomized design, and the agronomic trait data were comprehensively evaluated using the membership function method. The results showed that 23 coix seed germplasm resources had great differences in agronomic traits. After comprehensive evaluation using the membership function method, 8 coix seed germplasms with excellent comprehensive performance were screened out, which are suitable for use as excellent breeding materials and excellent parents of new varieties.
