Dr David Chagné

PositionHonorary Senior Research Fellow
DepartmentDepartment of Biochemistry


My research focuses on the application of genetic mapping and genomics to elucidate the genetic control of important plant characters. I have a strong underpinning interest in the study of DNA variations in plant genomes. I have catalogued single nucleotide polymorphisms (SNPs) in the apple and pear genomes and led an international project that has sequenced the European pear genome. Using this information, I have identified markers linked to significant traits, including fruit antioxidant content, red flesh and peel, crispness and aroma. I designed a SNP assay that has been used to accurately predict fruit quality of young apple seedlings using genome-wide selection, years before they first set fruit.
