Taking advantage of the consulting and sorting relevant data of millet spicy resources, we carried out a field survey at 29 counties of 13 prefectures in Yunnan Province. 86 of millet spicy resources were obtained, including six types of yellow and white shells, shallow green shells, green shells, dark green shells, purple black shells and golden yellow shells. These accessions were over-represented at the low altitude regions, southern parts of Yunnan. The density gradually decreased with the elevation of altitude. For instance, the germplasms found at areas with low altitude and high temperature were small and fruity. The altitude of germplasms showed positive correlation with the fruit shape and pulp thickened, but negative correlation with the spicy flavor. Taken together, this study provided information and datasets for the classification, protection and development of Yunnan's millet spicy resources.
