| 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-NIRSystem 6500 were developed. Calibration was focused on the possibility of screening seed samples of different composition of oleic acid (C18:l), 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 F 2 generations after crossing between lines with different contents of FA and lines with standard content of FA in oil ranged from 32.3 to 82.0% for C18:l, 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, r = 0.86 for C18:l, r = 0.82 for C18:2 and r = 0.85 for C18:3. Non-destructive NI

- Na základě měření NIRS (spektroskopie v blízké infračervené oblasti) u souboru 262 vzorků řepky ozimé s různým obsahem mastných kyselin (MK) v oleji byly vypracovány kalibrační rovnice pro přístroj Foss-NIRSystem 6500. Kalibrace byla zaměřena na možnost selekce vzorků semen s rozdílným složením kyseliny olejové (C18:1), k. linolové (C18:2) a k. linolenové (C18:3). Referenční metodou byla plynová chromatografie (GC). Obsahy sledovaných MK ve štěpících generacích F2 po křížení linií s rozdílným obsahem MK a linií se standardním obsahem MK byly 32,3 – 82,0 % pro C18:1; 10,2 – 26,8 % pro C18:2 a 3,3 – 11,8 % pro C18:3. Ověření validační rovnice u 50 náhodně vybraných vzorků F2 štěpící generace v roce 2006 prokázalo vysoké korelační koeficienty (r) mezi analýzou NIRS a GC a to r = 0,86 pro C18:1, r = 0,82 pro C18:2 a r = 0,85 pro C18:3. Nedestrukční metoda NIRS umožňuje rychlou a spolehlivou identifikaci materiálů s rozdílnou skladbou MK v semeni řepky (linie s vysokým obsahem C18:1 a nízkým obsahem C18:3 (cs)
