对甜高粱与粒用高粱正反交 F 1代杂交种的杂种优势及其主要农艺性状进行了比较分析。结果表明：只有穗粒重表现出明显的群体超亲优势，按均值大小排顺序为：单株生物产量＞穗粒重＞株高＞穗长＞锤度＞生育期。甜高粱与粒用高粱正反交 F 1代主要农艺性状单株生物产量、含糖量、穗粒重、株高、穗长和生育期6个性状之间的差异不明显。
對甜高粱與粒用高粱正反交 F 1代雜交種的雜種優勢及其主要農藝性狀進行瞭比較分析。結果錶明：隻有穗粒重錶現齣明顯的群體超親優勢，按均值大小排順序為：單株生物產量＞穗粒重＞株高＞穗長＞錘度＞生育期。甜高粱與粒用高粱正反交 F 1代主要農藝性狀單株生物產量、含糖量、穗粒重、株高、穗長和生育期6箇性狀之間的差異不明顯。

The hybrid heterosis and the main agronomic characters of reciprocal cross F 1 generation between sweet sorghum and the grain sorghum are analyzed and compared.The results showed that only ear grain weight shows obvious group transgression advantage.According to the average value,the order of heterobeltio-sis order was biomass yield of single plant >ear grain weight >height >ear length >brix >growth period.As there were no obvious difference between the main agronomic traits,including biomass yield of single plant,ear grain weight,brix,height ,ear length,growth periodof reciprocal cross F 1 generation between sweet sorghum and the grain sorghum in the inheritance of six traits.
