Abstract: In this paper, cluster analysis and correlation analysis were carried out on the agronomic traits of 224 millet varieties from different ecological regions. The results showed that the variation of 27 agronomic traits ranged from 11.20% to 110.70%. And, the variation degree of each agronomic trait from large to small was effective panicle number, grain color, panicle weight, grain weight per panicle, grain number per branch, straw weight per plant, caryopsiscolor, ear shape, stem thickness, grain shape, plant color, spike neck shape, spikelet density, panicle diameter, sterile lemma color, bristle length, ear length, panicle length, bristle color, anther color, inverted two leaves width, heading stage, 1 000-grain weight, plant height, number of knots, leaf posture and inverted two leaves length. The spike grain weight per plant was positively correlated with spike weight and grass weight per plant. Clustering analysis based on Ward Deviation Square Sum showed that 224 millet varieties could be divided into six groups while the Euclidean Distance was 19. The group Ⅰ（including 83 samples） had a short growth period and belonged to early maturity type, with a large 1 000-grain weight and thick tassels, but other traits were of medium level, and the group Ⅱ（including 64 materials） had a relatively short growth period, and the spike weight and grain weight were higher in all groups. Group Ⅲ（including 41 materials） had the longest growth period and belonged to late maturity type, with higher plant height, less tillering and lower yield, while group Ⅳ（including 25 materials） had a longer growth period, belonged to middle late maturity type, lower plant height, less tillering number and lower middle yield. Group Ⅴ（including 1 material） had a longer growth period, belonging to middle late maturity type, with longer setae, narrower leaves, higher plant height, more tillers, the largest grass weight per plant, 1 000-grain weight and yield belonging to middle and upper level, and group Ⅵ（including 5 materials） belonged to early maturity type, with long bristle length, shortest inverted two leaves, shortest plant height, more tillers and lower yield.
