摘要
Abstract
To study the agronomic traits and difference of different millet varieties,and the relationship between the main agronomic traits and yield of millet,and screen out high-quality and high-yield millet varieties,variance analysis,correlation analysis and principal component analysis were conducted on 35 millet varieties in Aohan Banner respectively.The results showed that yield was significantly positively correlated with the single ear weight,with a correlation coefficient of 0.426.Ear length is extremely significantly positively correlated with stem length,with a correlation coefficient of 0.489.Plant height is significantly positively correlated with ear diameter,with a correlation coefficient of 0.376.The single ear weight is significantly positively correlated with ear length,with a correlation coefficient of 0.362.The findings indicated close relationships between growth factors and yield formation factors,which collectively determine final yield.The yield promotion can focus on enhancing nutrient accumulation in the early stage and optimizing cultivation measures.Principal component analysis reduced to the main two components,with a cumulative contribution rate of 83.09％.Further,based on the comprehensive scores and yield traits,it can be known that Menghonggu No.2,Jinmiao k7,Jinmiao k4,Jinmiao k8,Chigu k6,Zhongzagu 29,and LeiguGK33 were suitable to be cultivated and spreaded as millet varieties with good comprehensive traits in Aohan Banner.关键词
