Putative QTLs for seed yield and BEC traits in the TNDH population under different B conditions.

Note:a, short names of the traits: BEC, boron efficiency coefficient; SY, seed yield; SW, seed weight; PH, plant height; SN, seed number; PN, pot number; BN, branch number.b, Nomenclature for QTL: an trait abbreviation following a boron-level designator (LB, low B level; NB, normal B level), a hyphen (-), chromosome (A1-A10 or C1-C9) on which the QTL located and the serial letter (a, b, c…) in the same linkage group.c, Additive effect. Positive additive effects are associated with increased effects from B-efficient parent allele, and negative additive effects are associated with increased effects from B-inefficient parent allele.d, Percentage of phenotypic variation explained (PVE) by each identified QTL.e, The 2-LOD confidence interval (CI) of QTL, given in cM.f, The peak position is denoted by the number in parentheses.
