摘　　要：目的通过应用灰色关联度分析方法对糜黍品种生长发育与主要产量构成性状遗传关系进行综合评价,以期提高糜黍品种(品系)选择效率,缩短育种年限,加速新品种的推广.方法选用张选1号、张选2号、张选6号和冀(承)黍1号4个糜黍品种的9个主要经济性状,运用灰色关联度分析方法,与产量的关系进行分析比较.结果4个糜黍品种的9个经济产性状与产量的关联度大小依次为:基本苗、有效穗数、总茎数、穗粒重、千粒重、单株粒重、主穗长、生育期、株高.结论糜黍品种选育时,在保证基本苗和千粒重稳定的前提下,应注重提高品种的分蘖能力、成穗率,也要提高穗粒重,单株粒重.Objective To improve the broomeorn millet breed （strain） choosen efficiency, shorten the breeding years and accelerate the new breed spread, the grey related degree analysis are employed to study genetic relationship between the growth and major yield component traits in four broomcorn mille breeds. Methods The main 9 economy traits from 4 broomcorn millet breeds including Zhang-Xuan 1, Zhang-Xuan 2, zhang-Xuan 6 and Ji （Cheng） -Shu 1, were selected and used to compare and analize the relationship with the output using the method of the grey related degree analysis. Results The result showed an order about the related degree from large to small： the basic seeding, effective tillers, total stem number, weight per spike, 1000-grains weight, grain weight per plant, main spike length, growth stage, and plant height. Conclusion During the period of broomcorn millet being breed, it should be emphasized to increase the ability tillering, percentage of earbearing tiller, weight per spike and grain weight per plant under the condition of basic seeding and 1000-grains weight ensure stability.
