Analysis of the SC8-0071-014 and sc47-18 loci co-segregated with <i>Ren1</i> gene in the genotypes of seedless grape varieties

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 vine resistance genes powdery mildew, inherited from V. vinifera ; linked for this locus known. A 34 seedless genotypes was carried out using SC8-0071-014 sc47-18 co-segregated with . In studied sample varieties, 12 types alleles were identified 9 locus. Target fragments, according marker loci, indicating presence gene, variety Lotus (Kriulyanskiy x Yangi Er).
