Abstract	A randomized complete block design with three replications was used in Sakrand and Tando Jam, Sindh, Pakistan, to assess the simple correlation, coefficient of determination and regression coefficient of ten commercial wheat genotypes (Mehran-89, Moomal-2002, Anmol-91, Pavon, Maxi-Pak, Abadgar-93, TJ-83, Yecora, Z.A-77 and T.D-1). The characteristics studied were plant height (cm), tillers per plant, spike length (cm), spikelets per spike, grains per spike, seed index (g) and grain yield per plant (g). A highly significant positive correlation was observed between tillers per plant and grain yield per plant (r = 0.57**), and the highest positive regression value (byx=2.01) was recorded between spike length and grain yield per plant in Tando Jam. In the Sakrand environment, the highest positive correlation coefficients were found between tillers per plant and grain yield per plant (r=0.78 **), tillers per plant and seed index (r=0.77 **), spike length and spikelets per spike (r=0.81 **) and spike length and grains per spike (r=0.70 **); the highest positive regression coefficient value (byx=3.67) was recorded between seed index and grain yield per plant.
