对近几年从国外引入的高粱种质资源的２２个性状进行调查研究表明，抗丝黑穗病、抗蚜、抗旱、抗叶病、抗倒伏等综合抗性表现普遍较好。国外不育系与中国恢复系组配的杂交种产量性状表现较好，杂种优势强，有些甚至可以直接应用。非迈罗雄性不育细胞质的引入，扩大了雄性不育细胞质的遗传多样性。Ａ３、Ａ４型雄性不育细胞质可改变不育系选育程序并在育种中加以利用。
The investigation of 22 traits of sorghum germplasm introduced from abroad in recent years showed that the comprehensive resistance to head smut, aphids, drought resistance, leaf blight resistance and lodging resistance was generally good. The yield traits of hybrids between foreign sterile lines and restorer lines of China performed well, with strong heterosis. Some of them could even be applied directly. The introduction of non-Milo male sterile cytoplasm expanded the genetic diversity of male sterile cytoplasm. The male sterile cytoplasm of A3 and A4 can change the CMS breeding program and make use of it in breeding.
