These overview data have been partially presented by Bianco et al.²² The number of genotyped seedlings has been updated after data curation in the current study during the construction of the iGLMap: 16 pairs of identical individuals were discovered across 6 families for which only 1 individual per pair was kept in the final data set; thus, a total of 16 identicals were removed. The involved families were 12_B (1 pair), DLO.12 (6 pairs), FuGa (1 pair), FuPi (1 pair), GaPi (3 pairs), I_M (1 pair), I_W (1 pair), JoPr (1 pair), and PiRea (1 pair). In addition, two individuals, 12_B058 and 12_J025 that showed a very high recombination rate (>5.0) in almost all linkage groups were considered out-crossers and excluded from the final data set. Most of these populations were part of the previous European project HiDRAS,⁴¹ and four of them derived from other previous studies as reported in the last column. Pedigrees of the X-numbered accessions are given in Bink et al.¹³
