Estimation of the Fatty Acids Content in Intact Seeds of Oilseed Rape

Original language description

Based on NIRS (near infrared reflectance spectroscopy) measurements carried out in a collection of 262 samples of winter oilseed rape with a different content of fatty acids (FA) in oil, calibration equations for the laboratory instrument Foss-NIRSystem6500 were developed. Calibration was focused on the possibility of screening seed samples with various composition of oleic acid (C18:1), linoleic acid (C18:2) and linolenic acid (C18:3) using NIRS analysis. The reference method was gas chromatography (GC). The content of FA in segregating F2 generations after crossing between lines with various content of FA and lines with standard content of FA in oil ranged from 32.3 to 82.0% for C18:1, 10.2 ? 26.8% for C18:2 and 3.3 ? 11.8% for C18:3. The verification of a validation equation in 50 randomly selected samples of F2 generation in the year 2006 proved high correlation coefficients (r) between NIRS analysis and GC values, respectively r = 0.86 for C18:1, r = 0.82 for C18:2 and r = 0.85 f
