Fine mapping of the QTL at the end of Pv03. a The allele frequency difference between fast- and slow-imbibing pools at the QTL region. Each dot represents the TARS-HT1 allele frequency in the fast-imbibing (red) and slow-imbibing (blue) pools. b-c represent the detected QTL region using ΔSNP-index (b) and G′ (c) methods, respectively. d The haplotype map of 30 individuals that were whole-genome sequenced to narrow down the position of the QTL. The individuals were separated based on their water uptake phenotype. A 118 kbp region was detected (surrounded by red lines) that possessed PR9920–171 alleles (light blue) in slow imbibing genotypes. The same region had TARS-HT1 alleles (dark blue) for the fast imbibing genotypes. Three individuals were detected that were heterozygotes (dark gray) in the 118 kbp region and expressed the slow-imbibing phenotype. The red lines highlight the fine mapped region and its corresponding positions in the initial BSA
