Abstract
The results of the analysis of allelic polymorphism of the Rpf1 red stele root rot resistance gene in strawberry hybrid forms using diagnostic DNA markers were shown. The recessive homozygous genotype (rpf1rpf1) was identified in strawberry seedlings 932-29 (F. virginiana subsp. platypetala (Rydb.) Staudt × Feyerverk), 933-4 (F. virginiana subsp. platypetala (Rydb.) Staudt × Rubinovyy kulon), 62-7, 62-23 (Bylinnaya × Feyerverk), 65-2, 65-15 (Olimpiyskaya nadezhda × Bylinnaya) and 35-16 (922-67 × Maryshka). The heterozygous state of the Rpf1 gene was identified in strawberry forms 69-29 (Feyerverk × Bylinnaya), 62-41 (Bylinnaya × Feyerverk), 72-24, 72-71 (Privlekatelnaya × Bylinnaya), 65-17, 65-24 (Olimpiyskaya nadezhda × Bylinnaya), which allows them to be used in breeding for resistance to P. fragariae var. fragariae as valuable initial forms.
