DFCR - Biotic Stress Research Group

Field crops are influenced by several biotic stresses, which have impact on quality and quantity of  grain yield. Resistance against pathogens of cereals is very important factor of yield stability. Several agrotechnical  methods are used to protect crops against pathogens, but role of genetic resistance is determinative. Those varieties and hybrids which are resistant against several pathogens at the same time possess economic preference. By economical aspect viral and fungal diseases of plants are the most important ones. In our complex research program we study the resistance mechanisms of plants under field conditions, the molecular genetic background of resistance and population genetics of pathogen fungal populations. We also develop new biological methods in plant protection by the use of pathogen-antagonist microorganisms.
