摘要
本文应用灰色系统理论关联度法对杂交高梁的产量及其他主要农艺性状进行了评估。结果表明：不同杂交组合的同一性状与产量的关联度不同；同一组合内的不同性状与产量的关联度也不同。其关联度顺序为：单穗粒数（ｒ４＝０．９００８）＞穗长（ｒ３＝０．８００５）＞茎粗（ｒ２＝０．７０８０）＞株高（ｒ１＝０．６７８６）＞单穗粒重（ｒ５＝０．６５１６）＞千粒重（ｒ６＝０．５４９０）。
By using the method of relational grade analysis of the grey system theory,yield and other major agronomic characters of hybrid sorghum were evaluated .The results showed that the same character of different hybrid combination had a diffrerent correlation degree with yield;The different characters of the same hybrid combination had a different correlation degree with yield. The order of grey correlation degree is:Kernel number per ear (r4=0.9008)>ear length(r3=0.8005)>diameter of stem(r2=0.7080)>plant height (r1=0.6786)>Kernel weight per ear (r5=0.6516)>1000-Kernel weight (r6=0.5490)
