Enhancing sweet cherry breeding in the UK: Insights from genotyping-by-sequencing and genome-wide association studies

Published 2024년 3월 5일

Tridge summary

A 2023 study in Horticulture Research used a collection of 116 sweet cherry accessions to examine 23 fruit quality traits. Using genotyping-by-sequencing for high-density SNP analysis and genome-wide association studies, the research identified 65 unique SNP-trait associations for eight traits. It also found several candidate genes related to phytohormone, calcium, and cell wall metabolisms. These findings improve our understanding of the genetic factors influencing sweet cherry fruit quality and aid in the development of marker-assisted selection strategies for breeding.

Sweet cherry (Prunus avium L.) is one of the most economically important perennial fruit species growing in temperate regions. However, partly due to climate change and biological pressures from pathogens, sweet cherry production in France has been declining since the 1980s.Meanwhile, traditional breeding is a long process because of the extended juvenile phase and complex polygenic traits. Advances in genetic research, including quantitative trait locus (QTL) mapping and genome-wide association studies (GWAS), have identified markers for key traits but are limited by the need for extensive genotyping. Genotyping-by-sequencing (GBS) emerges as a promising solution, offering a cost-effective method for high-density SNP analysis to enhance breeding strategies.In September 2023, Horticulture Research published research titled "Genome-wide association mapping in a sweet cherry germplasm collection (Prunus avium L.) reveals candidate genes for fruit quality traits."This study first ...
