  1. Genetic change in last 9 years (ΔG) and genetic level in the last year (G) within scheme measured in genetic SD units of the trait (production or adaptation), and rate of inbreeding per generation (ΔF) in percentages with standard error (SE) over five replicates. The selection index weighted adaptation and production equally in A1P1, by 2:1 ratio in A2P1, respectively, and by 1:2 ratio in A1P2, respectively
  2. aThe A, P and AP schemes used only adaptation line (AL), production line (PL), or combined AL and PL synthetic line individuals, respectively. The AiP scheme used introgression from AL to PL, and the PiA scheme used introgression from PL to AL. In the rAiP scheme, there was no selection in the AL donor line used in introgression
