STUDYING POTENTIAL WINTER RESISTANCE OF COLORIFICATIONS AND GENOTYPES OF WINTER SOFT WHEAT BY ANALYSIS OF AUTO-FLUORESCENCE OF TISSUE PROTEINS

Winter crops of cereals are the most productive component of acrocyanoses, but in the conditions of the Russian Federation, large losses in the yield of winter grain crops occur due to damage and death of plants under unfavorable conditions of wintering, the main of which is the effect of low temperatures in the late autumn, winter and early spring periods. The task of determining winter hardiness of winter grain crops in a simple and fast way is relevant. In our work, the relationship between lignin content and plant resistance to frost has been studied. Winter wheat plants with different genotypes for the CAD1-F gene responsible for frost resistance are analyzed. A fluorescence analysis was also carried out in a number of varieties with known frost resistance.It was found that the higher the lignin content in the plant of winter soft wheat, the higher its frost resistance. A method of autofluorescence has been developed that makes it possible to evaluate varieties and genotypes of winter soft wheat for frost resistance.
