  • The average genetic gain in GY across cycles was estimated for each location and across both locations including all selection cycles (C0–C4), and including only the genomic selection cycles (C1–C4). Least significant differences (LSD) test at the 0.05 probability level including all selection cycles (C0–C4) and only the genomic selection cycles (C1–C4). The highest value is indicated in boldface.
