Abstract

Virus diseases of potato are widespread in Uzbekistan. The amount of damage they cause depends on many factors, including the biological characteristics of the variety.

In potato varieties, plant productivity decreases to varying degrees under the influence of viruses. The amount of damage caused by viruses depends on the species. In both studied varieties, this indicator was 6-9% for virus X, 15-28% for virus C, and the effect of leaf curl virus reached 18-33% under the influence of these factors, i.e. The biological characteristic of varieties in terms of damage by viruses is great. As a result of latent infection of potatoes with Y-virus, it was found that, depending on its biological characteristics, the productivity of varieties is reduced by 13.6-24.0%.
