Table IV.
Overview of peak LOD positions of QTLs (LOD >2.65) for various early vigor traits in the F4 RIL population of A. tauschii, derived from the cross between accession PI603228 and Ciae4
LK, Linkage group; TA + number, chromosome number in T. aestivum; positions in italic, positions of putative QTLs (1.5 < LOD < 2.65); ± sign in brackets, positive response/negative additive effect of the QTL; text in bold, the target traits of the path diagrams of Figure 1, A to C.
