Abstract
The experiment has aimed to evaluate the yield stability of maize hybrids on paddy field in dry season. 5 elite maize hybrids compared to 5 commercial maize varieties in four locations during November 2021 - April 2022. The experimental design was RCBD with four replications. The results from combined analysis showed that the elite maize hybrids yielding an average between 1,035-1,269 kg.rai-1 and 1,152-1,401 kg.rai-1 for the commercial hybrid maize varieties. The stability analyzed Eberhart and Russell method good and stability varieties must have high yields. The b are not different from 1 and the S2d are not different from 0, CP303 Pac789 NS5 and elite maize hybrid NSX152067 respectively, yielding 10 - 22% higher yields than check varieties NS3 (1,152 kg.rai-1). The order of desirable genotype of NSX152067 was inferior to CP303, Pac789 and NS5 but superior to NS3 NS4 and all other elite maize hybrids. NSX152067 has yield stability and suitable for paddy field in dry season.
