The present study was conducted at Barani Agricultural Research Station, Fatehjang, during rabi 2011-12 to evaluate variability, heritability, genetic advance, character association and their causal effects on grain yield plant-1 in ten wheat genotypes viz. BARS-09, AARI-11, Punjab-11, Millat-11, Chakwal-50, Lasani-08, NARC-09, Seher-06, Auqab-2000 and 05FJS3074. All the genotypes demonstrated highly significant differences for all the traits. Grain yield plant-1 had positive and significant correlation at both genotypic and phenotypic levels with 1000-grain weight and harvest index, number of tillers plant-1 and spike length but non-significant with number of spikelets spike-1 and flag leaf area. 1000-grain weight showed maximum direct effect (0.7298) towards grain yield plant-1 followed by number of tillers plant-1 (0.6638), harvest index (0.4021) and spike length (0.2629) while lowest direct effect was contribute by flag leaf area (-0.1196). High heritability genetic advance was exhibited by number of tillers plant-1, harvest index and grain yield plant-1 that confirms their additive gene action. Characters like; 1000-grain weight, spike length, number of tillers plant-1 and harvest index should be considered in selection procedure towards improvement in grain yield plant-1 indirectly.
