Abstract: To construct core collection of foxtail millet landrace in Shanxi, improve the utilization efficiency of germplasm resources, a random sampling was conducted after system clustering by Ward’s method. 11.34% of the initial collection was chose as the primary core collection. The results showed that the mean difference percentage (MD) of phenotypic traits between the core collection and initial collection was 5.9% , the coincidence rate of range (CR) was 87.4% , the variance difference percentage (VD) was 35.3% , and the variable rate of coefficient of variation (VR) was 102.0%. The t-test of Shannon-Weaver diversity index showed the primary core collection could represent the genetic diversity of the initial collection.
