Abstract

The results of the estimation of resistance in spring barley samples to net blotch pathogens, helmsntosporious root rots and the damage caused by swedish fly larvae in the laboratory and field condition are shown. The effi- cacy of application of the developed method for seed planting in autumn in field conditions to estimate spring barley specimens‘ resistance to various types of helminthosporiose is established. Seven samples having individual resistance to the complex of biotical factors, one sample with group re- sistance to diseases and another sample with complex resistance to net blotch and swedish fly, have been found
