a Manhattan plot on 21 wheat chromosomes for fruiting efficiency at harvest (FEh) in Balcarce 2013. Red line represents the GWAS threshold of P <0.05 = −log10 (P-value) = 1.3 and blue line represents the GWAS threshold of P <0.001 = −log10 (P-value) = 3. Red square highlights the Chr5A-B43-Hap1 associated with FEh in five of ten tested environments. b Haplotype block based on seven SNP markers located between 476.44 and 476.67Mb on chromosome 5A, named Chr5A-B43. Four different haplotype variants (Hap1–Hap4) are present at different frequencies in the analyzed population. Red rectangle highlights the Chr5A-B43-Hap1 associated with FEh. c Boxplots indicate the phenotype values corresponding to the four different haplotype groups in the three evaluated locations. Hap1 was associated significantly high FEh in all locations
