Abstract: 【Objective】To evaluate the yield stability and adaptability of spring-sown millet varieties in the Loess Plateau of northwest Shanxi,as well as the representativeness and discrimination of each experiment site,provide a theoretical basis for the rational layout of millet varieties in the northwest Shanxi and the selection of experimental site for millet variety identification.【Methods】The GGE biplot was used to analyze the yield stability,adaptability,and environmental discrimination and representativeness of 12 millet varieties(lines) tested in 8 experimental sites on the Loess Plateau in northwest Shanxi Province in 2021 and 2022.【Results】The impact of variety(line),environment,and the interaction between variety(line) and environment on the yield of millet showed a extremely significance. The 8 experimental sites are divided into two ecological zones,with Yuanping,Pianguan,Linxian,and Baode as the same ecological zone,Wuzhai,Jingle,and Lanxian as another ecological zone,and Xingxian′s results over the past two years had been unstable and unable to be divided.Among the 12 tested millet varieties(lines),Changnong No. 35 and Changnong No. 47 showed high and stable yields,suitable for planting in 8 experimental sites on the Loess Plateau in northwest Shanxi;Changsheng No. 13 had good yield but is unstable,suitable for planting in Wuzhai,Jingle,and Lanxian;Jingu No. 21 had good stability but low yield;However,the yield and stability of Cheng 15-m328 were poor,making it unsuitable for planting on the Loess Plateau in northwest Shanxi.【Conclusion】The high-yield and stable millet varieties suitable for planting on the Loess Plateau in northwest Shanxi Province are Changnong No. 35 and Changnong No. 47.The 3 experimental sites of Linxian,Jingle,and Pianguan have high discrimination and representativeness,and are ideal experimental sites for identifying millet varieties;The 3 experimental sites of Yuanping,Wuzhai,and Baode have strong discrimination but insufficient representativeness,making them suitable for screening millet varieties with poor stability.
