Genetic mapping and identification of a QTL determining tolerance to freezing stress in Fragaria vesca L.

ABSTRACT: Extreme cold and frost cause significant stress to plants which can potentially be lethal. Low temperature freezing stress can cause significant and irreversible damage to plant cells and can induce physiological and metabolic changes that impact on growth and development. Low temperatures cause physiological responses including winter dormancy and autumn cold hardening in strawberry (Fragaria) species, and some diploid F. vesca accessions have been shown to have adapted to low-temperature stresses. To study the genetics of freezing tolerance, a F. vesca mapping population of 143 seedlings segregating for differential responses to freezing stress was raised. The progeny was mapped using 'Genotyping-by-Sequencing' and a linkage map of 2,918 markers at 851 loci was resolved. The mapping popu
