Abstract：The first-time application of FTIR to analyzing and comparing two sweet pepper seeds lines of space mutation and two sweet pepper seeds lines bred in system approaches as well as their spectra is presented. The IR spectrum of sweet pepper seeds lines is mainly composed of the band of adsorption of protein and that of carbohydrates. The absorbance of the two sweet pepper seeds lines of space mutation at 2 854，1 652, 1 542 and 1 160-1 062 cm-1 was enhanced. The peak near 2 854 cm-1 is attributable to the stretching vibration of CH2—, The dominating bands near 1 652 and 1 542 cm-1 were assigned to amide Ⅰ and amide Ⅱ respectively. The absorbance at 1 160 cm-1 is attributable to the stretching vibration of C—O on the structure of carbohydrates. The major components and the structures remained intact，indicating that the space environment can increase carbohydrates and protein content of sweet pepper seeds lines.
