L.E. Kolesnikov, E.A. Vlasova, A.A. Vinogradov
During 2001-2006 years the authors have investigated the winter wheat leaf blotch’s development on 137 collection samples of soft wheat. It was established that the most of wheat leaf blotch resistant samples was introduced from USA and was made up on basis of Triticum aestivum var. lutescens. It was marked that the greatest resistance to disease was shown with samples from mixed population of Triticum aestivum L., has been compounding of milturum and lutescens varieties. The graphic models indicating interrelations between various parameters of wheat leaf blotch agent’s development were constructed.
Key words: wheat leaf blotch, soft wheat, simulation of pathogenesis.
