11种帚用高粱形态特征分析

[Objective] To provide a theoretical basis for high-yield breeding of broom sorghum. [Method] Using 11 kinds of broom sorghum collected at home as research objects, the differences in morphological characteristics of broom sorghum were compared through the survey of some indicators, such as plant height, tillering, inflorescence, stem node, stem-leaf ratio, yield, and so on. [Result] The 11 kinds of broom sorghum were different in morphological characteristics with large amplitude of plant height; zygl-1, zygl-6, zygl-8 and zygl-9 were appropriate for fixed broom type; zygl-9 had the highest integrated production. [Conclusion] The study laid the foundation for further exploring breeding, cultivation and promotion of broom sorghum.
