  • LOD, logarithm of the odds; GI, gall index; EGR eggs/g of root; SCMR, SPAD chlorophyll meter reading; SN, seed number; SW, seed weight; Pod_Constr, pod constriction; PL, peg length; MSH, main stem height; LBL, lateral branch length; NLB, number of lateral branches; LBL, lateral branch length; ADW, aerial dry weight; RDW, root dry weight; RRA weight ratio root/aerial part; TB, total biomass; PV, pollen viability.

  • a Linkage group.

  • b Map position in Kosambi cM.

  • c Maximum LOD score.

  • d Positive values indicate that higher-value alleles come from A. duranensis K7988, and negative values indicate that higher-value alleles come from A. stenosperma V10309.

  • e Proportion of the total phenotypic variance explained by the QTL.
