摘 要: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 hybrid vigor between sorghum and sudan grass was obvious. F 1 was higher than mid-parent, even higher than high-parent in growth, plant height, leaf length and width, fresh weight per plant, tiller and yield. The experimental results in several years showed that yield of the hybrid between sorghum and sudan grass was higher significantly than that of sudan grass. The hybrid could be planted in wide area, the nutrient level of the hybrid was close to that of sudan grass, and the palatability of the hybrid was superior to sudan grass. Several experiments were failed because the hybrid between sorghum and sudan grass was on a trial stage to this day. The reason of failure was caused by unsuitable cultivation practices, not the hybrid itself. Therefore it was believed that the planting area of the hybrid could be inlarged in the future.
