Genotypic values attained through selection cycles.

<p>Maximum of the true genotypic values among selected plants. (a) Solid lines show results of the discrete GS breeding. Dashed lines represent the maximum value of genotypic values in F₆ population derived from a single cross. Red and blue lines respectively represent the results of Koshihikari × Hatsushimo and the results of the best population in each simulation trial. (b) Red, green, and blue lines respectively present results of the discrete GS of Koshihikari × Hatsushimo population, one of the bulked GS, and one of the island-model GS.
