Abstract: 【Objective】To screen high-quality and high-yield foxtail millet varieties suitable for promotion and cultivation in the western Henan Province（Western Henan）,and provide references for the sustainable development of the local foxtail millet industry and the new variety breeding.【Methods】Taking 29 foxtail millet varieties as the experimental materials,variety screening experiments were conducted continuously for 4 years（2019—2022） at different locations in the western Henan Province（Yichuan County,Luoning County,Luolong District and Ruyang County）,and 8 agronomic traits,6 nutritional quality indexes,and yield of the participating varieties were determined;comprehensive evaluation was conducted through correlation analysis,cluster analysis and principal component analysis,and the relevant trait indexes were ranked by using the grey correlation degree analysis method.【Results】In the multi-point experiment over 4 years,the ones with better agronomic traits were Changnong 35,Jinuomi No. 2,Zhonggu 2,Yugu 35,Yugu 31,Dongchangjingu,Jigu 39,and Yugu 18;the ones with better yield and nutritional quality indexes were Jigu 20,Yugu 36,Jigu 17,Tiansu No. 1,Jingu 21,Changsheng 13. In 2019,Yichuan County had the highest yield,which was 5 162.01 kg/hm². The crude fibre content was extremely significant positive correlated with plant height and crude ash content,and stem diameter with moisture（P<0.01）,while plant height was extremely significant negative correlated with ear width,crude fibre content with stem diammer,ear width,weight per ear,moisture,and carbohydrate content with crude protein content（P<0.01）. Cluster analysis divided the tested varieties into five groups;principal component analysis indicated that the cumulative contribution rate of the five principal components was 72.577%;the top 5 foxtail millet varieties with the highest scores in the comprehensive evaluation were Jigu 17,Jinuomi No. 2,Jigu 38,Jigu 37 and Jigu 20. Grey correlation degree analysis indicated that the indexes most closely related to the quality of foxtail millet were leaf width（0.806 9）,leaf length（0.803 7）,crude protein content（0.803 6）,crude fat content（0.801 4）,and panicle length（0.800 7） in sequence.【Conclusion】Jigu 17,Jinuomi No. 2,Jigu 38,Jigu 37 and Jigu 20 have better comprehensive performance,stronger adaptability and higher nutritional quality,are more suitable foxtail millet varieties for cultivation in the western Henan Province.
