摘　　要：农艺性状相关性研究是种质资源和遗传育种研究中普遍采用的分析方法,明确各农艺性状之间的关系可为谷子品种选育和推广提供科学依据。对新育成的4个早熟杂交谷子品种在冀西北坝上地区的种植表现进行评价,结果表明,4个品种抗逆性均好,但不同品种的经济性状和产量存在较大差异;对其株高、穗长、单穗重、穗粒重、千粒重、出谷率和产量7个农艺性状进行相关性分析,结果表明,穗粒重与单穗重呈极显著正相关,产量与单穗重呈显著正相关、与穗粒重呈极显著正相关。穗粒重和单穗重是影响冀西北地区早熟杂交谷子产量的重要因素。The correlation study of agronomic traits is a widely used analysis method in the research of germplasm resource and genetic breeding.Clarifying the relationship between agronomic traits can provide scientific basis for the selection and promotion of millet varieties.The planting performance of 4 early-maturing hybrid millet varieties in Bashang area of Northwest Hebei Province was evaluated.The correlation analysis of seven agronomic traits,such as plant height,ear length,single ear weight,grain weight per ear,1000-grain weight,percentage of grain and yield was carried out.The results showed that the 4 varieties had good resistance to stress,but the economic characters and yield of different varieties were quite different.The grain weight per ear was significantly positively correlated with the weight per ear,and the yield was significantly positively correlated with the weight per ear,and was significantly positively correlated with the grain weight per ear.The grain weight per ear and the weight per ear were the important factors affecting the yield of earlymaturing hybrid millet in Northwest Hebei.
