Abstract：In the present paper, 25 garlic samples from different geographical populations were studied. FTIR spectra for each sample were obtained by using Fourier transform infrared spectrometer, and the similarity of garlic samples from different geographical populations was compared through “quick comparison” function in software of the spectrometer. The results showed that there are differences among FTIR spectra of garlic samples from different geographical populations.The quick comparison showed that the similarity is from 76.3% to 99.8% and the diversity of differentiation is more obvious. To some extent, the results reflected the effects of populations environment on physical and chemical properties of garlic. The study provided a simple, rapid, non-destructive and new methods for identification and evaluation of garlic germplasm resources.
