Abstract: In order to accurately select foxtail millet varieties with high and stable yield and broad adaptability,this study utilized best linear unbiased prediction(BLUP)data instead of raw yield for GGE biplot analysis.The analysis was conducted on 9 foxtail millet varieties and 14 test sites of National Foxtail Millet Variety Regional Adaptability Joint Evaluation Trial(North China Summer‑sowing Region)in 2023—2024.The results showed that,heatmap and ANOVA comparisons demonstrated that BLUP data decreased the variation coefficient of yield,and could better represent the genetic potential of variety.Notably,BLUP data explained 94.95% of total yield variation,which was obviously higher than that of raw data(72.51%),improving analytical precision.GGE biplot analysis using the BLUP data revealed that Yugu 101,Zhenggu 678 and Zhonggu 855 had higher yield;Hangu 6,Zhonggu 855 and Cang 471 had better yield stability;Yugu 101 and Zhonggu 855 had better comprehensive performance in yield potential and stability.Yugu 101 had the widest adaptability,followed by Zhonggu 855. Jinzhou(Liaoning Province),Taian(Shandong Province)and Anyang(Henan Province)sites were ideal test sites with strong discriminability and good representativeness.Overall,Yugu 101 and Zhonggu 855 are ideal foxtail millet varieties with high and stable yield and broad adaptability,suitable for promotion and cultivation in the North China summer millet region.

摘要: 为准确筛选丰产性、稳产性好和适应性广的谷子品种,利用最佳线性无偏预测(BLUP)数据代替产量原始数据对2023—2024年全国谷子品种区域适应性联合鉴定(华北夏谷区组)试验的9个谷子品种和14个试点进行GGE 双标图分析。通过对比热图和方差分析结果发现,BLUP数据降低了产量变异系数,能够更真实地反映品种的遗传潜力;同时,对产量总变异的解释(94.95%)明显高于原始数据(72.51%),提高了分析的准确性。利用BLUP数据进行GGE双标图分析发现,豫谷101、郑谷678和中谷855丰产性较好,邯谷6号、中谷855和沧471稳产性较好,豫谷101、中谷855丰产性和稳产性综合表现较好;豫谷101适应性最广,其次是中谷855。辽宁省的锦州、山东省的泰安和河南省的安阳3个试点是具有较强区分力和较好代表性的理想试点。综上,豫谷101、中谷855是丰产性、稳产性、适应性均较好的理想谷子品种,适合在华北夏谷区推广种植。
