ABSTRACT

A collection of the 3 Czech winter and 3 spring wheat varieties (harvest years 2008–2010) was evaluated in terms of the solvent retention capacity (SRC) method as well as common milling and baking quality parameters. Thousand kernel weight values did correspond to varieties quality sorting, but it was (as usual) significantly higher for the winter than spring wheat type the winter than the spring type of wheat (44.3 and 38.6 g, respectively). According to PSI hardness, samples belong to category very soft (‘Samanta’, ‘Sirael’ PSI 31–35%) and medium hard (‘Sultan’, ‘Sakura’, ‘SW Kadrilj’, ‘Septima’; PSI 17–20%). The F-test proved stronger impact of the harvest year on the variability of Solvent Retention Capacity (SRC) profile. According the water SRC, all three harvest years (2008, 2009, 2010) were statistically different (averages 61.0, 56.4 and 51.0%, respectively). According a new SRC characteristic, the gluten performance index (GPI), winter and spring types of the Czech wheat were slightly discriminated (averages 0.70 and 0.77, respectively). Correlation analysis results confirmed some known relations within the four SRC’s as well as to quality technological characteristic. For lactic acid SRC, relationships to the thousand kernel weight, the falling number and the one-stream flour yield (-0.60, -0.62, P = 0.01; and -0.49, P = 0.05, respectively) were determined. The strongest link was revealed between the GPI and the thousand kernel weight (-0.67, P = 0.01).

Key words: SRC, GPI, technological quality, wheat variety, harvest year.
