Free lipids (FL), bound lipids (BL) and total lipids (TL) were determined by the Soxhlet method in whole ground spelt (Triticum aestivum ssp. spelta L.) and hexaploid winter wheat (T. aestivum) samples. Ninety-one samples of spelt and 78 samples of winter wheat were analysed in the present study. The available material is representative of the wide variability found in spelt (true spelt forms compared with spelt wheat hybrid material). The results show that spelt differs from winter wheat by a higher FL and TL content (on average, 1·3 times and 1·2 times respectively). Furthermore, our results demonstrate that FL account for most of the high TL content of spelt as compared to winter wheat. Lipid content is a parameter which allows a distinction between spelt and winter wheat. This could be useful for breeders to classify spelt varieties.
