[目的]为帚用高粱高产育种提供理论依据。[方法]以国内搜集的11种帚用高粱为研究对象,通过对株高、分蘖、花序、茎节、茎叶比、产量等指标的调查,比较其形态特征差异。[结果]11种帚用高粱在形态特征上存在差异性,株高变幅很大,zygl-1、zygl-6、zygl-8、zygl-9适宜固定帚型,zygl-9综合产量最高。[结论]该研究为进一步探讨帚用高粱的育种、栽培、推广奠定了基础。 [Objective] The research aimed to provide theoretical basis for broom breeding with high yield of sorghum. [Method] With 11 kinds of domestic broom sorghum collected from China as the research object, the differences of morphological characteristics were compared through the investigation of plant height, tiller, inflorescence, stem section, stem-leaf ratio and yield. [Result] The morphological characteristics of 11 kinds of broom sorghums were different, and the amplitude of zygl-1, zygl-6, zygl-8 and zygl-9 was suitable for fixed broom type, and the yield of zygl-9 was the highest. [Conclusion] The study laid the foundation for further exploring breeding, cultivation and popularization of broom sorghum.
