  • Λ is the likelihood-ratio test statistic and ρ is the residual correlation. J-12, joint mapping for IB54 and IG1; S-1, separate mapping for IB54; S-2, separate mapping for IG1. The critical values of the test statistic (Piepho 2001) used to declare QTL were 20.57 for the J-12 analysis and 18.15 for each of the separate analyses (S-1 and S-2). Chr., chromosome.
