Fig. 2. Biplot based on diallel data of eight landraces for stover yield. Codes for genotypes are: A, ARZM 17–034; B, ARZM 03–056; C, ARZM 01–150; D, ARZM 03–054; E, ARZM 16–062; F, ARZM 16–042; G, ARZM 19–006; H, ARZM 01–088. Genotypes are labeled with uppercase letters when viewed as entries and with lowercase letters when viewed as testers. ATC, average tester coordinate.
