Abstract

The objective of this work was to establish a calibration equation and to estimate the efficiency of near‑infrared reflectance (NIR) spectroscopy for evaluating rapeseed oil content in Southern Brazil. Spectral data from 124 half‑sib families were correlated with oil contents determined by the chemical method. The accuracy of the equation was verified by coefficient of determination (R2) of 0.92, error of calibration (SEC) of 0.78, and error of performance (SEP) of 1.22. The oil content of ten genotypes, which were not included in the calibration with NIR, was similar to the one obtained by the standard chemical method. NIR spectroscopy is adequate to differentiate oil content of rapeseed genotypes.
