Abstract
The results of the analysis of promising strawberry genotypes by the chemical composition and genes, involved in the determination of fruit aroma, are presented. By the complex of chemical traits, the strawberry varieties and elite forms of breeding of the I.V. Michurin Federal Scientific Center are highlighted: Flora (sugars – 9.2%, ascorbic acid – 65.0 mg/100 g, anthocyanins – 74.2 mg/100 g), elite seedling 56-5 (Gigantella Maxim × Privlekatelnaya) (sugars – 8.1%, ascorbic acid – 83.5 mg/100 g, anthocyanins – 64.3 mg/100 g). These strawberry forms are also characterized by a homozygous state of the functional allele of the FaOMT gene of the aromatic complex of fruits, which indicates high mesifurane content in fruits. The research results can be used in further work on the creation of strawberry varieties with a high level of taste and aromatic qualities, and also the antioxidant value of the fruits.

Luk’yanchuk I. Molecular genetic analysis of strawberry genotypes for the FaOMT fruit aroma gene. BIO WEB OF CONFERENCES 2020.

Abstract
The results of the analysis of allelic polymorphism of strawberry varieties and forms for the FAOMT fruit aroma gene were shown. The non-functional allele FaOMT- in the homozygous state was detected in strawberry variety Quicky. Heterozygous genotype (FaOMT+FaOMT-) was identified in the strawberry varieties Feyerverk, Ostara, Polka and Symphony, and selected forms 26-5 and 928-12. The functional allele FaOMT gene (FaOMT+) in the homozygous state (FaOMT+FaOMT+ genotype) was detected in strawberry varieties Borovitskaya, Kubata, Troitskaya, Tsaritsa, Yarkaya, Korona and Vima Kimberly, and selected forms 932-29 and 298-19-9-43, which allows us to be used as valuable initial forms in breeding for fruit aroma.
