摘　　要：为促进东北春谷区优良谷子资源的利用及高产优质品种选育,利用东北春谷区2021年全国谷子品种区域试验数据,对参试的22个品种(系)的主要产量相关性状及抗性相关性状进行灰色关联分析,探讨各农艺性状与产量之间的关系。结果表明,22个谷子品种(系)产量相关性状的变异系数较小,而抗逆相关性状变异系数较大,变异幅度为1.32%~67.97%;19个谷子农艺性状与产量的灰色关联系数顺序为出谷率>单穗粒重>单穗重>生育期>公顷穗数>出苗期-抽穗期天数>千粒重>穗粗>抽穗期-成熟期天数>穗长>抗旱性>抗倒性>褐条病>株高>纹枯病>蛀茎率>谷瘟病>谷锈病>白发病,表明出谷率、单穗重、单穗粒重对产量的影响最大;各农艺性状之间具有较大的关联性,在选育高产优质谷子品种时,应注意选择生育期适宜且抗逆性较强的品种,同时还要注意种植密度。In order to promote the utilization of fine millet resources and the breeding of high-yield and high-quality millet varieties in the spring-sowing region of Northeast China,based on the national millet variety regional test data in 2021 in spring-sowing region in Northeast China,the grey correlation analysis was carried out on main yield related traits and resistance related traits of 22 varieties(lines)involved in the test,and the relationship between agronomic traits and yield was discussed.The results showed that the coefficient of variation of yield related traits of 22 millet varieties(lines)was small,while the coefficient of variation of stress resistance related traits was large,with a variation range of 1.32%-67.97%.The order of grey correlation coefficient between 19 agronomic characters and yield of millet was as follows:grain yield>grain weight per panicle>grain weight per panicle>growth period>number of panicles per hectare>days from seedling stage to heading stage>1000-grain weight>ear diameter>days from heading stage to maturity stage>ear length>drought resistance>lodging resistance>brown stripe>plant height>sheath blight>stem borer>grain blast>grain rust>white hair disease,indicating that grain yield,single panicle weight and grain weight per panicle had the greatest impact on yield;There was a great correlation between agronomic characters.When breeding high-yield and high-quality millet varieties,we should pay attention to the varieties with suitable growth period and strong stress resistance,and pay more attention to the planting density.
