Abstract：The erect panicle mutants of indica rice R1338 and R334 which came from Shuhui 498 muta-genesis by EMS as materials,so as to understand the reason of keeping spike erecting of erect panicle rice and provide reference for the application of indica erect panicle type rice. The results showed that the ben-ding resistance of panicle neck of R1338 and R334 were significantly higher than that of wild type variety R498;the contents of cellulose and lignin in panicle of erect panicle mutant were significantly higher than that in the wild type,contents of cellulose of R1338 and R334 increased by 2. 76% and 1. 64% compared with wild type,the contents of lignin of R1338 and R334 increased by 17. 89% and 7. 98%,respectively;erect panicle mutant had bigger stem diameter,more contents of cellulose and lignin,better mechanical strength compared with wild type,eventually their spikes could keep erecting.
