To investigate the influence of carbon ion irradiation on important agronomic characters of sweet sorghum

dry seeds of Sweet Sorghum BJ0601 and BJ0602 were irradiated by 100 MeV/u 12C+6 ion beam to different doses at Heavy Ion Accelerator National Laboratory in Lanzhou (HIANLL). When matured

the main traits of sweet sorghum were measured. The correlation coefficient of five main agronomic characters

i.e. number of node

plant height

stalk diameter

sugar content and stem weight per plant

were analyzed using the SPSS13.0 software. The results indicated that the obvious influence of sweet sorghum irradiated by carbon ion beam was observed. In addition

the correlation of main traits was studied. This study may provide rudimental data to select novel variety of sweet sorghum suited for fuel ethanol production. In addition

the average of sugar content of early mutant BJ0601-1 is higher than BJ0601 in M2

and the sugar content of sweet sorghum may be improved by carbon ion beam irradiation.
