There are results of studying of resistance and affection of plants in some potatoes sons by separate virus. It is noted the formation of infections background of virus in potatoes biocenos concerning to each sort and there is all opportunity to appear the new stamm in each of them in order to affect on others which are more resistant to existing stature of this pathogene.
