Study on the distribution of economically important viral diseases of cereal crops from 2014 to 2022 in Bulgaria
Zhelyu Avramov
Abstract: The production of cereals crop in recent years has become more energy-intensive with increased cost, which necessitated the introduction of increasingly high-yielding varieties of wheat, and in the case of barley, in addition to varieties and hybrids. Climate change has also had a major impact in recent years on the selection of wheat and barley varieties. These demands and changes necessitated the widespread adoption of varieties and hybrids of Western breeding. Along with this introduction, caused mainly by economic reasons, all preferred varieties of cereals turned out to be quite susceptible to economically dangerous diseases such as powdery mildew, septoriosis, bacteriosis and others. Viral diseases are no exception in this respect, moreover, there is even a filling of the hosts mentioned in the literary sources, but rarely encountered in agricultural practice, such as bromus mosaic (BMV) and barley strip mosaic (BSMV). The present study aims to establish the occurrence of all important virus infections during the period from 2014 to 2022, to ascertain the incidence of both mentioned and wheat streak mosaic virus (WSMV) and barley yellow dwarf virus (BYDV) in cereals and to indicate the varietal sensitivity. 208 plant and seed samples were analyzed by ELISA and 80 virus infections were found in 55 number of plant samples from all regions of Bulgaria. Data from the study will contribute to recommendations to farmers and regions, taking into account the prevalence and varietal susceptibility to the most economically important cereal crop virus diseases.
