The landscapes of log-likelihood ratio (LR) values testing the existence of two interacting QTLs controlling the total number of roots per cutting over different linkage groups. A. one QTL from linkage group 2 interacting with the second QTL from linkage group 2. B. one QTL from linkage group 2 interacting with the second QTL from linkage group 4. C. one QTL from linkage group 2 interacting with the second QTL from linkage group 7. D. one QTL from linkage group 2 interacting with the second QTL from linkage group 12. E. one QTL from linkage group 2 interacting with the second QTL from linkage group 14. F. one QTL from linkage group 6 interacting with the second QTL from linkage group 12. In each case, the peak of the LR landscape (shown by an arrow) beyond the threshold surface (indicated in grey) shows the positions of two epistatic QTLs. The names and positions of markers at each group are indicated.
