Existence the high G × E interaction test may necessitate additional zones thereby increase the cost of production important commercial cultivars. Researchers introducing different metrics to determine the stability of the cultivars have used. In this research 15 maize hybrids were studied in form of randomized complete block design with 4 replicates across 6 environments including 3 agriculture research center (Karaj, Mashhad and Jiroft) in two years (1390-1391). For studying interaction effect and determining stable hybrids, stability analysis using various methods was performed. In this study, some stability parameters were studied and calculated such as variance of genotype across environment(Si2), coefficient of variability (cvi), Wricke’s Ecovalance (wi2),Shukla’s stability variance (ơi 2 ), variance (MS y/l / ) and coefficient (CV y/l / ) within locations of Lin and Bins, Kang’s Yield-stability (YS i) statistic. Based on most methods used in this research genotypes number (6, 14, 5 and 10) were introduced as stable genotypes.
