The paper presents the symptoms of bydv during of the phenological stage: yellowing of leave, margins shading leaves, purple leaf coloration, blackened of plant. An unusual positive correlation was point out between purple leaf coloration, caused by virus, and percent of total protein content. some genotypes (Bogdana, Ursita, and Abundent) seems to have some resistance to virus.
