高粱和苏丹草之间的杂种优势十分明显，在生长状况、株高、叶长、叶宽、单株鲜重、分蘖等产量性状方面，Ｆ１均高于双亲平均值，甚至高于或接近于高亲。经多年试验，高粱—苏丹草杂交种的单位面积产量可显著高于苏丹草，适应范围也很广。经分析，它的营养品质与苏丹草相近，在适口性方面甚至优于苏丹草。但由于高粱—苏丹草杂交种目前尚处试验阶段，因此也有一些试点失败了，但大多属栽培管理不当所致，而不是“品种”本身所造成。因此可以相信，它的示范推广面积将不断得到扩大。
The heterosis between sorghum and sudangrass is very obvious. F1 is higher than the average of parents in yield status, plant height, leaf length, leaf width, fresh weight per plant, tillers and other yield traits, even above or near High pro. After years of testing, the sorghum-sudangrass hybrids yield per unit area can be significantly higher than sudangrass, adaptation is also very wide. Its nutritional quality is similar to that of Sudan grass and is even superior to Sudan grass in terms of palatability. However, since sorghum-sudangrass hybrids are still in the experimental stage, some pilot projects have failed, but most of them are caused by improper cultivation and management rather than “variety” itself. Therefore, it is believed that its demonstration area will continue to be expanded.
