GENETIC-BREEDING AND PHYTOPATHOLOGICAL STUDY OF RESISTANCE TO TAN SPOT OF WHEAT SAMPLES

Abstract

The results of our studies were aimed at identifying the immune and resistant to Pyrenophora samples of wheat, creation of new sources of resistance using genetic-breeding and phytopathological methods. The studies found that most of the studied samples (70,6%) were resistant to tan spot. Identified 2 promising lines with immune reaction to tan spot (IT – 0) and 39 lines of wheat with a moderately resistant reaction (IT – MR) to disease. Shown to be of particular interest to the present 4 breeding lines of wheat that combine high productivity and resistance to tan spot. Selected a promising material used in hybridization in breeding of winter wheat at increasing the productivity and resistance to tan spot. In the future promising lines of wheat can be used in breeding for resistance to spot as donors and candidates in future winter wheat cultivars
