In this research, the objective was to investigate whether quantitative trait locus (QTL) mapping could identify genomic regions that afect nut and kernel traits in the almond varieties Nonpareil and Lauranne and to investigate whether these regions have efects in two other almond populations (Nonpareil×Constantí and Nonpareil×Tarraco). Linkage mapping and QTL analysis were carried out using single-nucleotide polymorphisms (SNPs) that had previously been discovered using a set of 180 Nonpareil×Lauranne F1 progeny. With the Nonpareil×Lauranne population, QTLs were detected in ten regions on the Nonpareil map and 16 regions on the Lauranne map. Each Nonpareil QTL region and most Lauranne QTL regions were also detected using the Constantí and/or Tarraco populations. Most QTLs had small efects, indicating that the traits investigated here may be more suitable for genomic selection than for marker-assisted selection. With anchoring of QTL regions to genome sequence assemblies for Nonpareil and Lauranne, some candidate genes were identifed that could be evaluated in future research.en© The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2023.Almond; Quantitative trait loci; Nut traits; Kernel traits; Shell traitsJournal article10.1007/s11295-023-01630-w2023-11-28676903Goonetilleke, S.N.
