Estimation results of the spring bread wheat varieties on disease resistance in the Kazan Research Center

In the Republic of Tatarstan, due to favorable soil-climatic and market conditions, spring wheat production is developed, but grain yields are limited by a number unfavorable factors, one which spread fungal diseases. At same time, pressure pathogenic fungi makes it possible carry out fruitful breeding work in Tatarstan on resistance diseases, main activity Kazan Research Center RAS. The purpose current study was estimate ten new varieties for major leafy such as powdery mildew, stem rust, brown leaf dark blotch carried at natural infectious background, kernel smut an artificial background inoculating seeds with spores smut. between years 2017 2021. analysis presence rust genes performed PCR analysis. As result study, there found that ‘Sto let TASSR’, ‘Balkysh’, ‘Khazine’, ‘Chistopolskaya’, ‘Bulyak’ had complex all studied variety ‘Sitara’ strong field mildew ‘Barakat’ rust. ‘Nadira’ moderately resistant spot. ‘Ekada 265’ 282’ were highly local populations. molecular genetic estimation bread identification effective Sr-genes has shown their apparently regulated Sr31 gene.
