Abstract Grape powdery mildew caused by Erysiphe ne ca tor is a limiting factor in grape production. In order to develop effective management strategies, the factors influencing survival of fungus need be identified and characterized accordingly. For this purpose, we focused on effect weather conditions during overwintering viability ascospores. spring 2017 2018, leaf litter bark samples were c...

At the present stage of science development it is necessary to develop and implement grape breeding programs for immunity basing on international level knowledge about genetics pathogens that cause culture diseases. The extensive material genes resistance Plasmopara viticola Erysiphe necator ( Uncinula ), which mildew oidium diseases, has been collected thanks MAS technology. There an evidence ...

Powdery mildew ( Erysiphe necator ) is one of the most common and economically significant diseases grapes. The main method controlling disease pesticide treatment. To reduce chemical treatments, it necessary to select introduce resistant varieties into production. DNA markers are currently actively used in study grape genetic resources. Seedless highly demanded by consumers. Ren1 known mapped ...
