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 spike weight of 27 varieties of millet were analyzed by gray relational analysis. The results showed that the correlation of agronomic traits to ear weight was panicle weight> biomass yield> plant height> number of nodes> 1000-grain weight> panicle length. The most important impact on grain weight per panicle is panicle weight and biomass yield. Therefore, the selection of panicle weight and biomass should be emphasized in the high-yield breeding of millet.
