Ten nonparametric approaches carried out form twenty wheat genotypes crop through thirty five Environments within the rain fed areas of Pakistan for the year of 2016-17, developing periods have been used to principal cause of analyzing GEI throughout thirty five Environments. We study a few nonparametric technique were used for the Genotype’s Stability based of mean yield (𝒀̅), The S(1) statistic is used to compute the mean absolute rank difference between genotypes in different circumstances. As previously stated, S(2) represents the variance across environments, S(3) represents indicates the sum of square deviations in yield units from the mean classification, while S(6) represents the sum of absolute departures in yield units from the mean classification, with S(3) representing the variance across environments and S(6) representing the variance across environments. Kang's rank sum method RS, Thennarasu’s four non-parametric approaches (N(1) ,N(2),N(3),N(4) . Spearman’s rank correlation. S(1) stable genotype is G11(NR-443 ) and G10 (AZRC20 ), unstable genotype is G3 (14C040) and G8 (AZRC11). S(2) stable genotype is G10 (AZRC20 ) and G20 (WBG-14), unstable genotype is G2 (1V-11) and G14 (NR-488). S(3) stable genotype is G10 (AZRC20 ) and G20 (WBG-14), unstable genotype is G2 (1V-11) and G12 (NR-448). S(6) stable genotype is G10 (AZRC20 ) and G20 (WBG-14),unstable genotype is G19 (SD-1013) and G12 (NR-448). N(1) stable genotype is G10 (AZRC20 ) and G20 (WBG14),unstable genotype is G2 (1V-11) and G14 (NR-488). N(2) stable genotype is G7 (KT-325) and G6 (KT335),unstable genotype is G2 (1V-11) and G8 (AZRC11). N(3) stable genotype is G7 (KT-325) and G19 (SD-1013),unstable genotype is G15 (NR-491) and G8 (AZRC11). N(4) stable genotype is G11 (NR-443) and G10 (AZRC20),unstable genotype is G3 (14C040) and G8 (AZRC11). RS stable genotype is G3 (14C040) and G4 (14C036), unstable genotype is G12 (NR-448) and G7 (KT-325).
