In course of the research there was studied the accumulation of sugars in plants of winter cereal crops before going into winter. The selection samples and varieties of winter rye (Secale cereale), wheat (Triticum aestivum) and triticale (Triticosecale), which were grown in field conditions in the laboratory of winter hardness of the Scientific and Practical Center for Arable Farming of the National Academy of Sciences of the Republic of Belarus were used as a material for research in 2008 and 2009. Winter hardiness estimation was spent on the basis of calculation of the survived plants. Milled plant spectra was measured with use of a scanning spectrometer (NIRSystems 5000, USA) in a range of wave lengths of 1100-2500 nanometers with scanning step 2 nanometers. Processing of spectra and calculation regressive models were carried out with use of program WinISI v. 1.02 (InfraSoft, USA), entering into the spectrometer complete set. Based on the comparative analysis with Beitrand method it has been concluded that the use of near infrared spectroscopy for screening the samples with high stability potential is a prospective method.
