Ten wheat (Triticum aestivumL.) genotypes were evaluated for genetic variability for yield and association between different plant characters at Mountain Agricultural Research Station (MARC) Chilas during 2014-15.Analysis of variance revealed highly significant variation among different wheat genotypes for all traits studied. Genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) ranged from days to 50 % maturity (GCV=1.83, PCV=2.33) to grain weight yield per plot (GCV=18.48, PCV=18.59).PCV value for higher than GCV for all traits and narrow difference were found between GCV and PCV for most of traits. High heritability coupled with high genetic advance was estimated for traits like yield per hectare, total grain yield per plot, straw weight per plot and harvest index indicated these traits are under additive gene control and simple selection is effective for improvement of these traits. Yield per hectare showed positive and highly significant correlation with grain yield per plot (r = 0.989**), 100 seeds weight (r = 0.489**) and harvest index (r = 0.648**).
