Twenty four wheat genotypes including a check variety(Margalla-99) were planted in a Randomized Complete Block designwith three replications during 2001-02 at National AgriculturalResearch Center, Islamabad. Data were recorded and analyzed ondays to heading, days to maturity, plant height, spike length,number of spikelets per spike, number of grains per spike, grainweight per spike, 1000-grain weight and yield per plot. Thegenotypes were highly significant for all the traits except for yieldper plot where a significant difference was observed among thegenotypes. Maximum heritability was observed for days to heading(97.80 %) and days to maturity (87.60%), while a minimum value of24.27% was observed for yield per plot. Value of genetic advanceranged from a minimum of 0.06 for grain weight per spike to amaximum of 9.79 for yield per plot. The calculated correlationcoefficients indicated that number of spikelets per spike, days tomaturity and plant height were significantly positive correlated withgrain yield per plot, while a non significant correlation was observedbetween grain yield per plot and number of grains per plot, days toheading, grain weight per spike, 1000-grain weight and spike length.Genotype V1 and V15 performed better for most of the traits and canbe considered for release as varieties after further evaluation.
