Evaluation of stability in maize hybrids using univariate parametric methods

Abstract Genotype × environment interaction is one of the complex issues breeding programs to produce high-yielding and compatible cultivars. Interaction genotype make more accurate selection, performance stability hybrids need be considered simultaneously. This study aimed investigate stable genotypes with yield using 12 maize in different climatic conditions Iran. The experimental design used was a randomized complete blocks three replications two cropping years Karaj, Birjand, Shiraz, Arak stations. simple analysis variance performed on grain indicated that all studied each year station were significantly yield. Also, combined results showed significant effect environment, effects genotype, t different. Comparing Duncan's mean data obtained from research, KSC705 an average 7.21 KSC704 7.04 identified as high In order identify cultivars, six parameters used. KSC260 KSC707 had Based environmental variance, also based KSC705, coefficient variation, methods interaction. As well Eberhart Russell regression KSC400 SC647 genotypes. they most detection method, KSC707, KSC703
