Six parametric methods carried out form twenty genotypes yield of wheat throughout sixteen Environments within the rain fed areas of Pakistan for the year of 2016-17, developing seasons have been used to principal cause of analyzing GEI throughout 16 Environments. We study a few parametric method were used for the Genotype’s Stability based of mean yield (𝒀̅), Geometric adaptability index (GAI), Environmental variance (Si2 ), Wricke’s Ecovalence (Wi2 ), Shukla variance (σi2 ) and Co-efficient of variation (CV). The parametric measures result obtained by using wricke’secovelance and shukla’s results are same of stable genotype is G10 (AZRC-20), G5 (QS-3) and G17 (NW-520-1), unstable genotype is G2 (1V-11) and G16 (NW-1-8183-8). Environmental variance and Co-efficient of variation (CV) results are same stable genotype is G2 (1V-11) and G1 (1V-1), unstable genotype is G14 (NR-488) and G11 (NR-443). Geometric adaptability index (GAI) results stable genotype is G8 (AZRC-11) and G4 (14C036), unstable genotype is G7 (KT-325) and G19 (SD-1013). Genotype’s Stability based of mean yield (𝒀̅) results stable genotype is G11 (NR-443) and 16 (NW-1-8183-8), unstable genotype is G19 (SD-1013) andG7 (KT-325).
