[Objective] This study was to investigate the physical-chemical properties and the agronomical traits of a leaf color mutant K7231, so as to provide scientific basis for its use as breeding material. [Method] Before heading, the contents of chlorophyll and soluble sugar of leaf color mutant K7231 were measured, and its agronomic traits after mature were investigated. [Result] The contents of chlorophyll and soluble sugar of leaf color mutant K7231 before heading assumed a regular change law. Except the lower yield, K7231 performed similar agronomic traits compared with the CK. [Conclusion] This study provided scientific basis for the utilization of this mutant.
