abstract:
The objective of this study was to determine the relationships between chosen wheat physical and technological properties. Ten Polish spring wheat cultivars (Hezja, Kontesa, Torka, Zebra, Eta, Santa, Nawra, Jasna, Koksa, Kosma) were used in the study. The parameters recorded were: vitreousness, bulk density, the SKCS hardness index, grain strength properties and protein and gluten content, the Zeleny sedimentation volume, falling number and ash content. Investigations and their statistical analysis showed significant linear positive influence of the hardness index and force at the rapture point on the Zeleny sedimentation index (r = 0.75; 0.85). Additionally, those physical parameters were correlated with wheat protein content (r = 0.68; 0.82) and gluten content (r = 0.67; 0.82). The vitreousness of wheat grain was the most correlated with the Zeleny sedimentation index (r = 0.86).
