The commercial quality of foxtail millet grain (Setaria italica L.) includes appearance quality, functional quality, and cooking and eating quality, which directly determine whether consumers will purchase the product. We studied the relationship between ecological factors and commercial quality attributes of foxtail millet "Jingu 21" from twelve production areas. The results showed that altitude, latitude, and diurnal temperature range were negatively correlated with b*, total flavones content (TFC), setback (SB), consistence (CS) and pasting temperature (PTM), but positively correlated with L/B and breakdown (BD). In contrast, average temperature, average precipitation, average humidity, available nitrogen, phosphorus, and potassium had positive effects on 1,000-grain weight (KGW), b*, TFC, CS, and PTM and had a negative impact on L/B and BD. Climate factors had a greater effect on the commercial quality of foxtail millet than soil factors, and the influence of climatic factors was particularly obvious in the early and middle growth periods. The multivariate equation between ecological factors and the comprehensive score of foxtail millet commercial quality is Y = 1,159.745-4.496X (altitude) + 19.529X (≥10℃ effective accumulated temperature) - 166.327X (organic matters). In conclusion, high temperature and precipitation are conducive to high quality appearance and the accumulation of functional substances, while a high diurnal temperature range and high soil nutrients are conducive to the formation of cooking and eating quality. The impact of ecological factors on foxtail millet quality is complicated and it is essential to select a cultivation site that is matched to the intended use of the foxtail millet being produced.
黍稷商品品质包括外观品质、功能品质和蒸煮食味品质，直接决定消费者是否购买。本研究以 12 个产地的‘金谷 21’黍稷为试材，分析了生态因子与黍稷商品品质的关系。结果表明：海拔、纬度和日较差与 b*、总黄酮含量（TFC）、降落值（SB）、稀懈值（CS）和峰值黏度（PTM）呈显著负相关，与 L/B 和崩解值（BD）呈显著正相关；而年均温、降水量、平均相对湿度、有效氮、磷、钾与 1000 粒重（KGW）、b*、TFC、CS 和 PTM 呈显著正相关，与 L/B 和 BD 呈显著负相关。气候因子对黍稷商品品质的影响大于土壤因子，且气候因子对黍稷生长前期和中期的影响更为明显。生态因子与黍稷商品品质综合评分的多元回归方程为 Y=1159.745-4.496X（海拔）+19.529X（≥10℃有效积温）-166.327X（有机质）。总之，高温高降水有利于形成良好的外观品质和功能物质的积累，而较大的日较差和较高的土壤养分有利于形成良好的蒸煮食味品质。生态因子对黍稷品质的影响较为复杂，有必要根据黍稷的用途选择适宜的产地。
