Two hundred and twenty-two samples of single rice seed were scanned by FOSS Tecator Infratec 1255 Analyzer with Single Seed Adapter and the amylose contents were determined by reference method. With the powerful WinISI calibration maker software, several mathematics treatments to the sample spectra and several different regression methods were adopted to optimize a good calibration equation for determination of amylose content in a single rice grain. The standard error of calibration (SEC), standard error of cross-validation(SECV), validation performance (SEP) and regression squared (RSQ) of the calibration selected were 2.828, 3.088, 2.792 and 0.848, respectively.
