摘要
应用灰色关联度分析法对27个糜子品种(系)的主要农艺性状和穗粒重进行了分析。结果表明:各农艺性状对穗粒重的关联度从高到低依次为穗重>生物产量>株高>节数>千粒重>穗长。对穗粒重影响最大的是穗重和生物产量,因此,在糜子高产育种中,应注重对穗重和生物产量的选择。
The main agronomic characters and grain weight per spike of 27 Broomcorn millet germplasm were studied by grey relation grade analysis.The results showed that the order of them was as fallows： spike weightweight per plantstem heightnumber of node1000-grain weightspike length.The main characters such as spike weight and weight per plant had the closer relation with grain weight per spike,thus,should pay more attention to the choice of spike weight and weight per plant in high yield breeding of broomcorn millet.
