Assessment of the adaptive potential of strawberry genotypes based on the development of endophytic microbiota and identified R-genes

Abstract

The paper presents the results of a study of the strawberry genotypes (Fragaria L.) by characteristics of endophytic microbiota and genetic determinants of resistance to fungal pathogens. Highly adaptive genotypes were identified: F. virginiana Duch. ssp. platypetala, F. orientalis Los., F. ovalis Rydb., F. moschata Duch., 298-19-9-43, Urozhaynaya CGL, Flora, Privlekatelnaya and Troitskaya. These strawberry forms are characterized by a high frequency of testing of bacterial microbiota, which suppresses endophytic fungal pathogens. The wild strawberry F. virginiana Duch. ssp. platypetala is characterized by red stele root rot resistance (Rpf1 gene). Strawberry varieties Borovitskaya and Elianny are characterized by anthracnose resistance (Rca2gene).
