本文对黑亮、红壳、白亮三种类型苏丹草进行了穗形态、营养器官的形态学分析，结果表明穗轴长度、二级分枝数、茎节数差异性极显著；穗轴节数、一级分枝数差异性显著；三级分枝数、分蘖数及根冠比极不显著；单株可育小穗数目黑壳类型最多（16475．6粒／穗），白壳最少（5457．7粒／穗），红亮居中（9267．9粒／穗）；黑壳类型小穗颖片为黑色，长5－7mm，宽28－3mm；红亮小穗颖片为红色，长5－6．smm，宽2．5－3mm；白亮小穗为淡黄色，长55．6Cm，宽2．52．smm。
In this paper, morphological analysis of panicle morphology and vegetative organs of three types of sudangrass (black, red and white) was carried out. The results showed that there were significant differences in the length of panicle, the number of secondary branches and the number of stem segments. , The number of first-level branches was significantly different; the number of third-level branches, tillers and root / shoot ratio were extremely insignificant; the number of fertile spikelets per plant was the highest (16475.6 grains / spike) 5457.7 grains / spike), red center (9267.9 grains / spike); black shell type spikelets were black, 5-7mm long, 28-3mm wide; red bright spikelets were red, long 5-6. smm, width 2.5-3mm; white spikelets pale yellow, long 55.6Cm, width 2.52. smm.
