The Indonesian wide range of biogeophysical conditions lead to Genotype×Environment interaction (G×E). Multiple stability analysis methods can provide more comprehensive and reliable information about the G×E. The objective of this research was to determine the yield stability of seven promising maize (Zea mays L.) hybrids (SJI 1, SJI 2, SJI 3, SJI 4, SJI 5, SJI 6, SJI 7) and three control cultivars (Pioneer 36, Bisi 18 and Pertiwi 6) using Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, Shukla and GGE biplot analyses. The hybrids and cultivars were arranged in a randomized complete block design (RCBD) with three replicates in 10 locations in the dry season 2022. The results indicated that hybrid SJI 001 had the highest yield (12.57 t ha-1) and was stable according to the five stability analyses. On the other hand, hybrid SJI 002 (8.36 t ha-1 ) performed well in unfavourable environments, while hybrid SJI 006 (12.02 t ha-1) and ‘Pertiwi 6’ (11.48 t ha-1) performed well in favourable ones. In addition, GGE biplot analysis revealed that SJI 006 was well adapted to Prambon and ‘Pertiwi 6’ to Bajeng. © 2024, Instituto de Investigaciones Agropecuarias, INIA. All rights reserved.
