The test material originated from a field experiment conducted in 2011–2013, at the Experimental
Farm in Felin (51°22ʹ N, 22°64ʹ E), which belongs to the University if Life Sciences in Lublin.
A two-factor experiment was conducted in randomised blocks with 4 replicates. The chemical composition
of grain of 4 spring wheat species was analysed: common wheat (Triticum aestivum ssp. aestivum L.)
cv. Parabola, durum wheat (Triticum durum Desf.) cv. SMH 87, spelt (Triticum aestivum ssp. spelta (L.)
Thell.) cv. Blauer Samtiger, and emmer wheat (Triticum dicoccum (Schrank, Schubler) line PL 24062 (material
acquired from the National Centre of the Plant Gene Pool), grown at different production technology
intensity (medium and high level of cultivation technology). The analyses on wheat grain included the
content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium,
calcium, copper, iron, manganese and zinc. The results were subjected to an analysis of variance,
while the differences were estimated by the Tukey’s test at the significance level of p = 0.05. The were
calculated coefficients of variation (CV, %). Irrespective of the level of cultivation technology, husked
wheats had higher quality parameters compared to naked cultivars. Emmer wheat was characterised by
the highest content of proteins, ash, and macro and microelements in the grain and the spelt wheat cultivar
Blauer Samtiger was characterised by the highest fat content. Compared to the husked species, the common
wheat cultivar Parabola had the lowest content of proteins and ash, and a low content of macro and
microelements. Both the husked and the naked wheats had better quality parameters in treatments with
more intensive cultivation technology.
