"A Novel Introgression Line Collection To Unravel The Genetics Of Climacteric Ripening And Fruit Quality In Melon".

We developed a novel introgression line collection in melon using two commercial European varieties with diferent ripening behavior, the climacteric cantalupensis ‘Védrantais’ as recurrent parent and the non‑climacteric inodorus ‘Piel de Sapo’ as donor parent. The collection contains 34 introgression lines, covering 99% of the donor genome. The mean introgression size is 18.16 Mb and ~ 3 lines were obtained per chromosome, on average. The high segregation of these lines for multiple fruit quality traits allowed us to identify 27 QTLs that modifed sugar content, altered fruit morphology or were involved in climacteric ripening. In addition, we confrmed the genomic location of fve major genes previously described, which control mainly fruit appearance, such as mottled rind and external color. Most of the QTLs had been reported before in other populations sharing parental lines, while three QTLs (EAROQP11.3, ECDQP11.2 and FIRQP4.1) were newly detected in our work. These introgression lines would be useful to perform additional genetic studies, as fne mapping and gene pyramiding, especially for important complex traits such as fruit weight and climacteric ripening. eng Attribution 4.0 International A novel introgression line collection to unravel the genetics of climacteric ripening and fruit quality in melon info:eu-repo/semantics/article
