Abstract: Agronomic traits related to yield were comprehensively evaluated for 15 millet(Setaria italiea) varieties by correlation analysis and grey relation analysis. The results showed that there were significant differences in agronomic traits of millet varieties, and the coefficient of variation was 2.05%~22.66%. Six agronomic traits were significantly positively correlated with yield; the effects of agronomic traits on grain yield were 1 000-grain weight > grain yield > single panicle weight > growth period > grain weight per panicle > panicle length > plant height > panicle diameter. This indicated that the germplasm resources with prominent 1 000-grain weight, grain yield rate and single panicle weight should be utilized in millet yield breeding.

Key words: millet(Setaria italiea), grey relation analysis, agronomic trait, yield
