Selection of wheat varieties resistant to rust diseases on the basis of the study of valuable economic signs under conditions of Uzbekistan

Though population in Uzbekistan is supplied with grain products, the development of varieties resistant to biotic and abiotic environment factors is the main problem. Under the climate conditions of Uzbekistan more than 10 types of diseases cause damage to crops. In recent years, due to the widespread prevalence of stripe and leaf rust, farmers use fungicides, which significantly reduce the economic efficiency of production. The main reason is the application of varieties, which are not resistant to diseases, climate conditions favorable for disease development. The study presents the results of the comprehensive study performed on varieties of winter wheat, samples of the gene pool of CIMMYT and ICARDA brought from Russia and Commonwealth countries. The study was conducted on an artificially infected site in Tashkent region. As a result, there were revealed sources with high rates of valuable economic signs, resistance to stripe and leaf rust.
