Abstract
Anthracnose fruit rot (C. acutatum) is a dangerous strawberry disease. One of the ways to control C. acutatum in strawberry plantations is the cultivation of cultivars with genetic resistance to this pathogen. Among the genetic factors of strawberry anthracnose resistance is the Rca2 gene, which determines resistance to C. acutatum isolates of the pathogenicity group 2. Using the diagnostic DNA marker STS-Rca2_240, molecular screening of strawberry hybrid forms according to the Rca2 anthracnose fruit rot resistance gene was carried out. Promising strawberry hybrids characterized by a heterozygous combination of alleles of the Rca2 gene were identified: 2/1-24, 2/1-34 (‘Quicky’ × ‘Olympia’), 3/9-5 (‘Florence’ × ‘Faith’), 3/12-2, 3/12-9 (‘Alisa’ × ‘Quicky’), 4/7-10, 4/7-19, 4/7-20 (‘Asia’ × ‘Aprica’), and 5/2-26 and 5/2-32 (‘San Andreas’ × ‘Monterey’).
