Abstract

The comparative characteristic of biological, physical and chemical, and antigenic properties of the isolate bean yellow mosaic virus (BYMV) isolated from yellow lupine on the Chernihiv region territory. It is found that properties of BYMV-P isolate differ from the typical properties of strain BYMV (B-25) and isolates studied in Ukraine.

Highlights

  • Among various plant diseases, viral infections are one of the limiting factors reducing crop productivity and marketability and deteriorating product quality

  • Mantioned above virological situation demonstrates the need for special attention to control diseases induced by bean yellow mosaic virus in the virological monitoring system of agrocenoses

  • bean yellow mosaic virus (BYMV) detection agrocenoses of yellow lupine and investigation of its properties is important for ensuring effective control of viral diseases at all stages of growing varieties, development of diagnostic tools and measures to control this pathogen

Summary

Introduction

Viral infections are one of the limiting factors reducing crop productivity and marketability and deteriorating product quality. In Ukraine agrocenoses, among phytopathogenic viruses that can cause diseases of yellow lupine, the most common and economically important is bean yellow mosaic virus (BYMV, Potyviridae family, Potyvirus genus) [1; 2]. Involvement of lupine yellow crop with bean yellow mosaic virus, especially of late varieties, may be 50 to 90 % [3]. Reduced productivity of lupine plants affected with BYMV is determined by the phase of their development at the time of infection. BYMV detection agrocenoses of yellow lupine and investigation of its properties is important for ensuring effective control of viral diseases at all stages of growing varieties, development of diagnostic tools and measures to control this pathogen. The aim of our work was to detect, identify and investigate biological, physical and chemical, and antigenic properties of BYMV (isolate Progresyvnyi (Progressive), BYMV-P) isolated from yellow lupine in Chernihiv region
