| Abstract : | The aim of this study was to determine the milling value of four winter wheat cultivars (Bamberka, Bogatka, Muszelka, Tonacja) and two spring wheat cultivars (Bombona and Nawra). Grain originated from a production farm, from the crop years 2012-2014. The following parameters of grain were evaluated: test weight, kernel vitreousness and ash content. Grain was milled using an MLU-202 Bühler laboratory mill. The milling results of tested grain cultivars were analysed. The ash content of flour and milling efficiency factor K were evaluated. There was significant differentiation in milling value between tested wheat cultivars. The grain of winter wheat cultivars, compared with the grain of spring wheat cultivars, was characterised by lower ash content and higher yield of flour. Winter wheat cultivars – Muszelka and Tonacja – were characterised by the best milling value according to the milling efficiency factor K. Spring wheat cultivar – Bombona - was characterised by the least favourable parameters. Wheat grain from the crop year 2013 was characterised by the higher ash content and lower flour yield. There was significant positive correlation between test weight and kernel vitreousness. The yield of flour from breaking rolls was correlated negatively with test weight and kernel vitreousness. Whereas, total flour yield, reduction flour yield and shorts yield correlated negatively with ash content in grain. |
