Chile is a leader exporting fresh fruit however peach and nectarine arrive to final destination in quite poor conditions due to chilling injury. Therefore, if we can count on varieties that could maintain high quality after prolonged storage, the possibility of reaching distant markets with the Chilean fruit would increase significantly. As a way for enhancing peach breeding, in this project we propose that genomic re-sequencing and detailed phenotyping of individuals in peach would allow the identification of polymorphisms associated with fruit quality. The data obtained will be validated in commercial varieties. In this way, we foresee to generate tools that support our breeding program.
Identify and validate polymorphisms (SNPs and indels) associated to traits related to fruit quality in peach looking to optimize the production of new varieties.
- Phenotyping fruit quality traits in individuals from a segregating population and commercial varieties of Prunuspersica
- Analyze the metabolome of fruits from individuals from a segregating population that show ith contrasting phenotypes
- Re-sequencing the genome of individuals from a segregating population and identifying polymorphisms associated with fruit quality traits
- Validating the selected polymorphisms in segregating individuals from the program and commercial varieties.
